GE 369B1874G0019 Output Terminal Board for Generator Control Modules

Description

The GE 369B1874G0019 Digital Output Terminal Board is a robust and versatile module used in turbine control, excitation, and protection systems. It is commonly deployed within GE’s OC4000E and OC6000E distributed control platforms, where it serves as a key interface for managing digital output signals. This board features 16 relay-based outputs, allowing it to switch both AC and DC loads with high reliability. Engineers use it to control solenoids, contactors, alarms, and other field devices that require discrete signal activation. Moreover, the board is built for demanding industrial environments, offering stable performance in desulfurization, denitrification, and other emissions control systems. Its compact design and rack-mountable form factor make it easy to integrate into existing control cabinets. In addition to its switching capabilities, the board supports diagnostic monitoring and fault isolation, helping operators maintain system uptime and safety.
