Product Overview
The Schneider BMXEHC0200H High-Speed Counter Module is a specialized industrial automation module designed for applications that require the acquisition and processing of high-frequency pulse signals. In PLC-based control systems, conventional digital inputs may not always be suitable for rapidly changing signals generated by encoders, proximity sensors, photoelectric sensors, flowmeters, and other pulse-producing field devices.
A dedicated high-speed counter module provides a specialized interface for capturing fast pulse transitions and making the resulting counting information available to the PLC application. This allows the control system to monitor production quantities, machine movement, rotational activity, material travel, or other process variables associated with pulse signals.
The BMXEHC0200H can therefore be integrated into automation systems where accurate high-speed event counting is required. Depending on the application, the module can form part of a machine-control architecture involving sensors, encoders, PLC CPUs, HMIs, communication modules, and industrial actuators.
The supplied physical dimensions of the Schneider BMXEHC0200H are 32 × 103.7 × 86 mm, with a weight of 0.112 kg. Its compact size is suitable for modular PLC installations where cabinet space, wiring organization, and service accessibility must be considered.
Exact electrical input characteristics, counting frequency, channel configuration, counting modes, supported signal types, encoder compatibility, diagnostic functions, and configuration parameters should be confirmed against the applicable Schneider Electric documentation before engineering and commissioning.

What Is the Schneider BMXEHC0200H?
The Schneider BMXEHC0200H is a High-Speed Counter Module intended for integration into a compatible PLC automation system.
The primary purpose of a high-speed counter is to process pulse signals that may change too quickly for conventional cyclic PLC input processing to handle efficiently.
Industrial equipment frequently produces pulse signals as a result of physical movement.
For example:
- An encoder produces pulses as a shaft rotates.
- A proximity sensor produces pulses when products pass a detection point.
- A measuring wheel can generate pulses corresponding to material movement.
- A pulse-output flowmeter can generate pulses related to fluid flow.
- A speed sensor can generate pulses proportional to rotational activity.
The BMXEHC0200H provides the high-speed counting interface required to integrate such signals into a PLC control architecture.
A simplified signal path is:
Machine Movement → Pulse Sensor / Encoder → BMXEHC0200H → PLC CPU → Control Program → Machine Response
The PLC can then use the counter information for monitoring, calculations, sequencing, or control decisions.
High-Speed Counter Working Principle
Pulse Generation
The process begins with a field device that generates electrical pulses.
The pulse frequency may represent:
- Mechanical speed
- Rotational movement
- Product quantity
- Linear travel
- Material length
- Process flow
The exact relationship depends on the sensor and application.
High-Speed Signal Acquisition
The BMXEHC0200H receives the pulse signal through its field interface.
Because the module is designed specifically for high-speed counting applications, it provides an appropriate architecture for processing rapidly changing input signals.
Counter Processing
The module processes incoming pulse events and maintains the relevant counting information according to the configured operating mode.
The resulting value can then be incorporated into the PLC control application.
PLC Data Processing
The PLC program can use the counter information to calculate or monitor an engineering parameter.
For example:
Pulse Count → Scaling Calculation → Engineering Value → Control Decision
The resulting engineering value might represent:
- Number of products
- Machine position
- Shaft rotation
- Material length
- Machine speed
- Process quantity
The exact calculation depends on the application.
Why High-Speed Counting Is Important
A normal PLC scan continuously executes the control program and updates standard input information. However, high-frequency pulse signals may change multiple times during a single scan.
If a pulse signal changes too quickly, conventional input processing may not reliably capture every transition.
A dedicated high-speed counter architecture is therefore useful when the application depends on fast pulse acquisition.
High-speed counting can support:
- Accurate event detection
- Product counting
- Position monitoring
- Speed measurement
- Encoder feedback
- Material-length calculation
- Production monitoring
- Machine synchronization
The actual operating performance depends on the module configuration, field device, wiring, and system architecture.
Role in Industrial Control Systems
The BMXEHC0200H can operate as an interface between high-speed field devices and a PLC control system.
A representative architecture is:
Pulse Sensor → BMXEHC0200H → PLC CPU → Application Logic → Output Devices
The module handles the high-speed signal acquisition while the PLC performs the broader control and process-management functions.
The counter information may be used for:
- Machine sequencing
- Position-related calculations
- Production counting
- Speed monitoring
- Material tracking
- Synchronization
- Alarm generation
- Process monitoring
For example, in an automated packaging line, a sensor may generate a pulse whenever a package passes a specific location. The high-speed counter can acquire the pulse events, while the PLC uses the accumulated count to coordinate packaging operations.
Industrial Applications
Packaging Equipment
Packaging machines often depend on high-speed counting for:
- Product detection
- Product quantity counting
- Conveyor synchronization
- Cutting position
- Label positioning
- Registration control
A high-speed counter can provide the PLC with fast event information required by the machine sequence.
Conveyor Systems
Conveyors can use pulse signals to monitor movement and coordinate equipment.
Applications may include:
- Product counting
- Conveyor speed monitoring
- Material tracking
- Sorting
- Transfer synchronization
Encoder-Based Position Monitoring
Encoders provide pulse signals associated with mechanical movement.
The BMXEHC0200H can be used as part of a feedback architecture for monitoring compatible encoder signals.
Possible applications include:
- Rotary shafts
- Conveyor movement
- Linear positioning
- Material feed systems
- Machine axes
The exact position calculation depends on the encoder resolution and application configuration.
Material Measurement
A measuring wheel or other pulse-producing mechanism can provide information related to material travel.
The PLC can convert pulse counts into a corresponding length or distance value.
This approach can be used in applications involving:
- Cable
- Film
- Sheet material
- Wire
- Textile
- Continuous production materials
Flow Measurement
Certain industrial flowmeters provide pulse outputs.
When compatible with the high-speed counter interface, these signals can be acquired and processed by the PLC for process monitoring or quantity calculations.
Machine Synchronization
Fast pulse information can help coordinate multiple machine operations.
For example, the PLC can use a pulse count as a reference for activating a downstream actuator at a defined machine position.
Encoder and Sensor Integration
The BMXEHC0200H may be integrated with compatible pulse-producing field devices.
Potential devices include:
- Incremental encoders
- Proximity sensors
- Photoelectric sensors
- Tachometers
- Pulse-output flowmeters

The electrical characteristics of the sensor must be compatible with the intended module interface.
Before installation, engineers should verify:
- Signal type
- Signal voltage
- Pulse frequency
- Sensor power requirements
- Wiring arrangement
- Shielding
- Grounding
- Encoder characteristics
Exact compatibility should be confirmed using the applicable product documentation.
Counting Modes and Application Configuration
A high-speed counter application normally requires the control engineer to define how incoming pulses should be interpreted.
Depending on the system configuration, engineering considerations may include:
- Counting direction
- Counter reset
- Preset value
- Start condition
- Stop condition
- Pulse source
- Scaling
- Overflow handling
- Position reference
- Synchronization conditions
The available functions and configuration options should not be assumed solely from the general product category. They should be confirmed against the specific BMXEHC0200H hardware and software environment.
PLC System Integration
The BMXEHC0200H can form part of a modular PLC architecture containing:
- PLC CPU
- High-speed counter module
- Digital input modules
- Digital output modules
- Analog modules
- Communication modules
- HMI
- SCADA
- Sensors
- Encoders
- Actuators
A typical operating sequence is:
- A field sensor generates a pulse.
- The BMXEHC0200H detects the high-speed signal.
- The module processes the pulse.
- Counter information becomes available to the PLC application.
- The PLC program evaluates the information.
- The controller performs the required calculation.
- The PLC activates the appropriate outputs.
