Product Brief Description

The GE 369B1874G0022 is a Digital Output (DO) Terminal Board designed for industrial control applications. It specifically features 16 DC relay output channels, making it ideal for connecting control systems to devices that operate on a DC power supply. A key function of this board is to provide electrical isolation and reliable signal conversion, which is crucial for protecting the control system from potential electrical interference and faults from field devices.

Detailed Product Description

This terminal board acts as the interface between an industrial controller (such as a GE Mark VIe or EX2100e I/O pack) and up to 16 external DC-powered devices. The board receives low-power digital signals from the control system and uses these signals to switch the contacts of its internal relays. This allows a low-voltage control signal to activate a higher-voltage or higher-current DC circuit, such as a solenoid or a motor starter. The design of the board ensures high reliability and safety by using relays to physically isolate the control circuit from the power circuit.

Key Features and Specifications

Functional Role in a System

In an industrial setting, the 369B1874G0022 is mounted on a DIN-rail or chassis and connects to both the control system and the field devices. When the control system’s I/O pack sends a digital signal for a specific channel, the corresponding relay on the board is energized. The relay’s contacts then close, completing the DC circuit for the connected device. This design prevents a fault in the field device from affecting the sensitive control electronics of the main system.

Common Applications

This specific terminal board is used in a variety of applications where DC-powered devices need to be controlled:

  • DC Motor Control: Switching DC motor starters and contactors.
  • Solenoid Actuators: Controlling DC solenoids for pneumatic or hydraulic valves.
  • Safety & Signaling: Activating DC-powered alarms, indicator lights, and other signaling equipment.
  • Industrial Robotics: Providing control signals for robot end-effectors and other DC components.
