Product Overview
The GE IC695ALG626CA PACSystems RX3i Analog Input Module is an analog signal acquisition module used in GE PACSystems RX3i PLC systems. It provides the connection between industrial field instruments and the PLC control program by collecting continuous measurement signals from external devices.
Unlike discrete input modules that only identify switching conditions, the IC695ALG626CA processes variable analog signals generated by sensors and transmitters. It allows the RX3i controller to monitor real-time process values and use this information for control logic, alarm handling, data processing, and automation sequences.
The module is typically integrated into systems that require accurate process monitoring, including manufacturing equipment, process automation systems, and industrial machinery. It works together with RX3i CPUs, communication modules, output modules, and field instruments to build a complete automation control architecture.

Working Principle
The IC695ALG626CA operates by receiving analog signals from field devices and converting them into digital values that can be processed by the PACSystems RX3i CPU.
A simplified signal path is:
Process Sensor → Analog Input Module → Signal Conversion → RX3i CPU → Control Program
During operation, industrial transmitters and sensors generate electrical signals representing physical conditions such as temperature, pressure, flow, or level. The analog input module receives these signals and converts them into usable data values for the PLC system.
The RX3i CPU then processes the acquired information according to the application program, enabling functions such as monitoring, regulation, alarms, and automated control.
The module acts as the measurement interface between field equipment and the PLC software layer.
Role in PACSystems RX3i Control Architecture
The IC695ALG626CA operates within the signal acquisition layer of the GE PACSystems RX3i automation structure.
A typical system layout can be represented as:
Field Instruments → Analog Input Module → RX3i CPU → Output Modules → Industrial Equipment
| System Layer | Typical Function |
|---|---|
| Sensors / Transmitters | Provide analog process measurements |
| Analog Input Module | Converts signals into PLC data |
| RX3i CPU | Executes control logic |
| Output Modules | Drive actuators and equipment |
| Communication Modules | Exchange automation data |

Technical FAQs
What type of process information can the IC695ALG626CA collect?
The module is used for acquiring continuous analog measurements from industrial sensors and transmitters, allowing the PLC system to monitor changing process conditions.
How does an analog input module differ from a discrete input module in an RX3i system?
An analog input module processes variable measurement signals, while a discrete input module only detects binary states such as ON/OFF conditions.
What should be considered when connecting field transmitters to this module?
Signal type compatibility, wiring method, grounding conditions, PLC configuration, and transmitter settings should be verified before commissioning.
Why might an RX3i system show incorrect analog values after module replacement?
Incorrect configuration parameters, wiring errors, unsuitable signal settings, or problems with the connected field device can cause abnormal measurement readings.
