Description
The modules provide two independently controlled Form C contacts while utilizing only one address point at the Signaling Line Circuit (SLC). The two Form C contacts can be used for a variety of Normally Open and Normally Closed applications such as fan, elevator and door control, or auxiliary notification.
As the modules use mechanically latching relays, a separate 24 VDC power supply is not required.
They fit into a standard 4‐inch square or double‐gang electrical back box.
