CMMB102 Dual Mini I/O Module
The CMMB102 expands your BMS system over the BACnet or Modbus network when your application requires additional inputs and outputs on a physical controller. It provides simple expansion of a new or existing controller and reduces unnecessary costs of additional components. On-board LEDs help track and diagnose any input and output activity during operation.
