Product Brief Description
The GE 369B1874G0023 is a Digital Output (DO) Terminal Board that offers a unique combination of functionality. It features 16 relay output channels, specifically designed with 8 AC relay outputs and 8 DC relay outputs. This hybrid configuration allows a single board to interface with and control a diverse range of field devices that operate on both alternating current (AC) and direct current (DC) power supplies. Like other boards in its series, it provides essential electrical isolation to protect the control system from high-voltage and noise from connected equipment.
Detailed Product Description
This terminal board serves as a crucial link between a central control system (such as the GE Mark VIe or EX2100e) and external field equipment. It receives digital signals from the control system’s I/O pack and activates the appropriate relay contacts. The key feature is its ability to handle different power types: the 8 AC relays can switch AC circuits for devices like motors or large lighting systems, while the 8 DC relays can switch DC circuits for devices such as solenoids or safety alarms. This versatility simplifies system design and wiring in applications where both AC and DC control is required.
Key Features and Specifications

Functional Role in a System
In a complex industrial environment, the 369B1874G0023 can be a highly efficient component. For example, in a factory automation system, the DC relays could be used to control the operation of DC-powered pneumatic valves, while the AC relays could control the motors of conveyors or other AC-powered machinery. This integrated approach allows a single I/O module to manage both types of loads without the need for separate, dedicated terminal boards, streamlining the overall system architecture.
Common Applications
This specific board is well-suited for systems that require a combination of AC and DC control signals, including:
- Factory Automation: Controlling a mix of AC motors and DC sensors or actuators on a production line.
- Building Automation: Managing both AC lighting circuits and DC-powered security systems or access controls.
- Power & Energy: Used in power plant control systems to switch both AC circuit breakers and DC safety equipment.
- Marine & Offshore: Ideal for vessels or platforms where a variety of AC and DC equipment must be controlled from a central point.
