Product Brief Description
The GE 369B1874G5005 is a Digital Output Base (BDO23) module that serves as an Extension Relay Board. It is specifically designed to provide 8 channels of relay output for controlling devices that operate on 220V DC power. The module is a part of the Nexus Controls system, designed to extend the capabilities of a primary controller.
Detailed Product Description
This module, identified as a BDO23, is a specialized component used in industrial automation and control systems. It acts as a slave module to a main controller, providing additional high-voltage DC output channels. Unlike the previous BDO12 and BDO20 modules, this specific part number is configured for a higher voltage of 220VDC. This makes it suitable for heavy-duty industrial applications where higher DC voltages are present. The relays on the board provide essential electrical isolation, protecting the sensitive logic of the main controller from the high-voltage circuits it controls.
Key Features and Specifications
- Part Number: 369B1874G5005
- Module Type: Digital Output Base (BDO23)
- Channels: 8 relay outputs
- Load Type: Specifically for 220V DC loads
- Function: Extends the I/O count of a main control module
- Benefits: High-voltage DC capability, electrical isolation, system scalability, and robust control for demanding applications.
Functional Role in a System
Within a control system, the BDO23 module receives a low-voltage control signal from the main controller. It then uses this signal to energize its internal relays, which switch the high-voltage 220VDC power to connected field devices. This separation of control and power circuits is a standard safety and design practice in industrial settings, allowing a single controller to manage a wide range of powerful equipment.
Common Applications
The ability to handle 220VDC makes this module suitable for more powerful DC applications, such as:
- High-Power Industrial Machinery: Controlling large DC solenoids, brakes, and actuators.
- Utility & Power Systems: Actuating DC-powered breakers and other equipment in a power substation or plant.
- Heavy-Duty Robotics: Managing high-voltage DC motors and servo systems.
- Emergency Systems: Controlling backup power systems and DC-powered emergency lighting.
