Product Overview
The ABB 1MRK000614-ABr04 Binary Output Module is a digital output component used in industrial protection, electrical control, and automation systems. Its main purpose is to transfer switching commands from the control system to external electrical circuits and connected field devices.
A binary output generally works with two defined states, making this type of module suitable for equipment that needs a clear on/off command rather than a continuously adjustable signal. In an industrial system, the output can be used for relay operation, alarm indication, interlocking functions, switching commands, and other discrete control tasks.
The 1MRK000614-ABr04 is normally installed as part of a larger ABB protection or control system. The main processor or application logic determines when an output should change state, while the binary output module provides the physical interface between the internal control logic and external wiring.
This arrangement keeps the control logic and field connections organized. It also makes it easier to connect protection equipment with breakers, relays, alarm circuits, and other electrical devices.
With dimensions of 225 × 25 × 187 mm and a weight of 0.5 kg, the ABB 1MRK000614-ABr04 has a compact form factor for industrial control and protection equipment.

Product Features
The ABB 1MRK000614-ABr04 provides a dedicated interface between a control system and external devices that respond to discrete electrical commands.
Key features include:
- Binary output signal capability
- Suitable for industrial protection and control applications
- Supports discrete switching commands
- Provides an interface between internal control logic and external circuits
- Suitable for relay, alarm, and interlocking functions
- Compact industrial module construction
- Suitable for integration into ABB control architectures
- Designed for field-level output applications
The module is useful when a protection or automation system needs to issue a straightforward switching command without using an analog output signal.
Working Principle
The 1MRK000614-ABr04 works on the output side of the control system. It receives an output command generated by the application logic and transfers the corresponding binary state to the connected external circuit.
For example, a protection system may determine that a breaker command is required. The control logic generates the corresponding output, and the binary output module transfers that command through the appropriate field connection.
The basic operating sequence includes:
- Receiving an output command from the control system
- Processing the required binary state
- Changing the corresponding output condition
- Sending the signal to the external circuit
- Allowing the connected device to perform its assigned function
- Maintaining the output state until another command is received
The module therefore acts as the link between software-based control decisions and physical electrical equipment.
Role in Industrial Control Systems
The 1MRK000614-ABr04 handles discrete output functions within an industrial protection or automation system.
| Function | Description |
| Binary Signal Output | Sends discrete signals to external circuits |
| Device Control | Provides commands for connected equipment |
| Alarm Signaling | Supports external alarm indication |
| Interlocking | Transfers discrete interlock commands |
| Protection Interface | Provides output signals for protection functions |
| Field Integration | Connects internal control logic with external equipment |
It does not normally perform the main protection algorithm or application logic. Those functions are handled by the associated control or protection equipment.
Industrial Applications
Binary output modules are commonly used in systems where a controller needs to send clear switching commands to external electrical equipment.
| Industry | Typical Applications |
| Power Generation | Generator control and protection |
| Power Distribution | Switchgear control |
| Electrical Substations | Breaker and protection control |
| Manufacturing | Machine switching functions |
| Energy Systems | Electrical protection and automation |
| Infrastructure | Electrical monitoring and control |
| Industrial Facilities | Alarm and interlocking circuits |
| Process Automation | Discrete equipment commands |
In power and protection applications, binary outputs are particularly useful for functions that require a defined switching state, such as alarms, trips, interlocks, and equipment control commands.
Installation and System Integration
The installation of the ABB 1MRK000614-ABr04 should be coordinated with the configuration of the host protection or automation system.
Recommended installation steps include:
- Verify the complete module part number.
- Confirm compatibility with the target ABB system.
- Install the module in the designated equipment position.
- Check connector and terminal identification.
- Confirm the requirements of the connected field circuit.
- Complete the wiring according to the system design.
- Verify output states during commissioning.
- Test the connected equipment before normal operation.
The output wiring should be checked carefully before energizing the system. An incorrect connection can cause an external relay, contactor, alarm, or switching device to respond unexpectedly.
Compatible System Components
The binary output module can form part of a larger protection and control architecture together with several other components.
| Compatible Component | Function |
| Protection Controller | Executes protection and control logic |
| Processing Module | Handles application functions |
| Binary Input Module | Receives discrete field signals |
| Relay | Transfers or isolates output commands |
| Circuit Breaker | Performs electrical switching |
| Contactor | Controls electrical loads |
| Alarm Device | Provides visual or audible indication |
| Control Power Supply | Supplies associated control circuits |
The actual configuration depends on the host ABB system and the specific protection or automation application.
Recommended Alternative Models
| Model | Type | Key Feature | Application |
| ABB 1MRK000614-ABr04 | Binary Output Module | Digital output interface | Protection and control systems |
| ABB Binary Output Modules | Digital Output Module | Discrete switching signals | Industrial automation |
| ABB Binary Input Modules | Digital Input Module | Field signal acquisition | Protection and monitoring |
| ABB I/O Modules | I/O Module | Field signal interface | Automation systems |
| ABB Protection I/O Modules | Protection I/O Module | Protection signal handling | Substation applications |
When selecting a replacement or alternative, the complete part number should be checked together with the host system, output configuration, electrical requirements, connector arrangement, and wiring. Similar dimensions alone do not confirm functional compatibility.
