CDH8 Connect Digital Series


The CDH8U5 is an intelligent LCM providing connections for multiple luminaires*, up to 5 presence detectors and SELV inputs. The product simplifies installation whilst providing an intelligent lighting control system. Provision is made for 4 volt-free power outputs rated for 415V isolation.

Additionally, the unit features a switched output for Maintained Live to allow initiation of Emergency Lighting Test. The CDH8U5 has the ability to operate from dual supplies with the capability to modify its operating behaviour when failure is detected on one of the supplies.
