DDC Network Expansion Controller
BICC-FF00K
BICC‑FF00K is a dedicated DDC network expansion controller for building automation systems. It works as a slave module and connects to the system by communicating with the DDC network IP main controller via the left LAN port. Equipped with dual LAN ports, its right port can further cascade other expansion devices. It supports external IO expansion modules and special function modules to expand system points and functions. Normally up to 4 IO modules can be extended, and the actual number of mountable modules is limited by the output power capacity of the unit. It can be applied to building automation and industrial control scenarios, compatible with various controlled equipment such as sump pits, supply and exhaust fans, fresh air units, air handling units, water pumps, central air conditioning, elevators, fire protection systems and lighting.
- The left LAN port communicates with the DDC main controller to connect to the DDC network;
- Dual LAN port cascading design: the right port can connect to other downstream expansion modules to support chain expansion;
- Compatible with external IO expansion modules and special function modules for control point and function expansion, with a maximum of 4 IO modules supported under normal conditions;
- The maximum number of external expansion modules is determined by the output power capacity of the expansion controller;
- Suitable for building automation and industrial control scenarios, compatible with various field devices such as fans, air conditioners, water pumps, lighting and fire protection systems;
- Acts as a communication relay to forward and exchange data between the main module and downstream expansion devices.
