Product Brief Description
The GE 369B1873G5003 BDI50 DI Terminal Module is a high-voltage digital input base designed for the GE Mark VIe control system. Unlike the BDI10 and BDI11, this module is specifically engineered to handle 16 digital input channels with a higher operating voltage of 125VDC. It serves as the primary termination point for wiring from field devices, connecting them securely to the system’s I/O modules.
Detailed Product Description
The 369B1873G5003, or BDI50, is a specialized module for applications that require a higher DC voltage level. Its design allows it to interface directly with field devices that output a 125VDC signal, eliminating the need for external voltage converters and simplifying the overall system architecture. With 16 channels, it provides a balanced solution for managing a moderate number of high-voltage digital inputs efficiently within the Mark VIe system, ensuring signal integrity and reliable data transfer to the controller.

Functional Role in a System
The 369B1873G5003 plays a critical role in systems where field devices operate on a higher voltage supply. It acts as a robust and reliable buffer, receiving the 125VDC signals from devices such as large breakers or high-voltage relays and safely converting them into signals that the Mark VIe I/O module can process. This ensures that the control system can accurately monitor the status of these high-voltage devices without any risk of damage.
Common Applications
This BDI50 module is essential for industrial control systems in environments where 125VDC is a standard operating voltage. Common applications include:
- Substation and Power Generation: Monitoring the status of large circuit breakers, disconnect switches, and protection relays that operate on 125VDC control power.
- Heavy Industrial Equipment: Interfacing with motors, pumps, and other heavy machinery where 125VDC is used for control circuits.
- High-Voltage Safety Systems: Handling inputs from emergency stop buttons and safety interlocks in a 125VDC environment.
