Neptronic CMMB102
The CMMB102 expands your BMS system over the BACnet or Modbus network when your application requires additional inputs 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 activity during operation.
Power: 24Vac or 24Vdc
