Product Brief Description

The GE 369B1873G0021 Digital Input Terminal Board is a high-density terminal board designed for the GE Mark VIe control system. Its main purpose is to provide a termination point for 32 channels of discrete (on/off) digital input signals. This board acts as a crucial interface, connecting field devices like switches, contacts, and sensors to the system’s Digital Input (IDIS) I/O pack. It is designed to work efficiently in simplex, dual, or triple modular redundant (TMR) systems, ensuring high reliability for monitoring critical signals.

Detailed Product Description

The 369B1873G0021 is a vital component for systems requiring a large number of digital inputs. It receives signals from field devices, and its terminal blocks provide a secure, organized point for wiring. The board is compatible with a specific I/O pack (often the IDIS pack), which processes the incoming digital signals and communicates them to the main controller. The board’s design is robust and often includes features for noise suppression and signal conditioning, ensuring the integrity of the digital signals in an industrial environment. The high channel count (32) makes it suitable for applications where panel space is at a premium.

Functional Role in a System

In a Mark VIe system, the 369B1873G0021 is the first point of contact for discrete signals from the field. Field wiring is connected to the board’s screw terminals. The board routes these signals to the corresponding I/O pack. The I/O pack digitizes the signals and sends the data to the system controller, which uses this information to monitor the state of various equipment, such as valve positions or motor status. In a TMR system, the board can be configured to fan a single signal to multiple I/O packs for redundancy.

Common Applications

This terminal board is used in any application where a large number of discrete signals need to be monitored by a control system. It is commonly found in:

  • Power Plant Control: Monitoring the status of circuit breakers, limit switches, and alarm contacts.
  • Process Automation: Reading the on/off status of pumps, fans, and safety interlocks.
  • Manufacturing: Monitoring the state of conveyor belts, production line sensors, and emergency stop buttons.
