- Connects the cabinet to a channel of the PROCONTROL remote bus
Their core function is to act as an intelligent bridge between field devices and the system bus, flexibly receiving analog signals (such as pressure and temperature) and binary switching signals. This series of modules features extremely high channel density and self-diagnostic capabilities. Each channel can typically be independently configured with filtering, calibration, and limit alarm functions, ensuring accurate and real-time acquisition of field data, providing a solid foundation for decision-making throughout the control system.
It incorporates comprehensive monitoring mechanisms that can detect transmitter power short circuits, line breaks, and internal hardware faults in real time, issuing immediate alarms via front panel indicator lights or the system bus. The module supports hot-swapping technology, allowing maintenance and replacement without interrupting system operation. Furthermore, its robust electrical design enables stable operation in harsh power plant environments with strong electromagnetic interference and extreme temperatures, making it a key component for ensuring the safe operation of energy infrastructure.
The GJR2397800R0100 81AR01A-E ABB Relay Output Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Its operating principle is based on distributed processing and standard bus communication: The module first receives raw electrical signals from field sensors through a monitored input interface and performs analog-to-digital conversion (ADC) or jitter suppression using an onboard microprocessor. The processed data undergoes engineering quantity conversion and verification according to preset logic, and is then encapsulated into standard telegrams with parity bits. Finally, this data is uploaded to the system bus via the PROCONTROL station bus interface for use by the controller or host; simultaneously, the module continuously executes a cyclic self-test program to ensure the integrity and authenticity of each transmitted signal.
Protection System Triggering: This is its most critical application. It is used to drive the trigger actuators of protection devices, such as turbine trip solenoid valves or boiler main fuel trip (MFT) relays. It is typically used in conjunction with the 83SR04 protection module.
Safety Interlock Management: This module features a unique 9th main relay that can simultaneously connect or disconnect all 8 functional units. This is used in safety “permission” circuits, where a single monitoring signal must be present before any individual output can be energized.
Emergency Stop (E-Stop) Circuit: Used to drive high-integrity safety relays to cut off power to industrial machinery or robotic arms in emergency situations.
High-Voltage Switchgear Control: Used in power generation and distribution, providing the dry contact signals required to control large circuit breakers and disconnectors.
