DA254: Access control Tri-relay module

Designed for extending critical control circuit loops for access control and fire systems, the Tri-relay unit is ideal for when installing new equipment or extending systems.

In the event of a loss of power within a circuit connected to Coil terminals, such as the triggering of an alarm or fire system, the three control relays will change-over.

The DA254 is available as a 12V DC or 24V DC device, with three SPCO relays with N/O and N/C contacts rated to 24V 5A DC, please refer to ordering information for available models.
