Description
BCDO0020HB is a modular I/O expansion module designed for use in boiler rooms and heating/cooling plants as part of a scalable control system. The module features 20 relay outputs, each rated for up to 5 A (resistive load), making it ideal for controlling pumps, valves, fans, and other switching devices. Communication with the interface module is handled via a high-speed HB bus, which also supplies power to the I/O module, reducing wiring complexity and installation time. Integration with Building Management Systems (BMS) is achieved through the interface module via Modbus TCP, while local configuration is supported through RS485 Modbus RTU. BCDO0020HB is optimized for reliable field performance and consistent operation in demanding environments. Its modular design allows for flexible control strategies and easy expansion of I/O capacity without major changes to system architecture. The unit is suitable for both new installations and retrofit projects requiring robust and distributed output control.
