Comelit 1256 Simplebus 10 A COM/NO/NC Network Relay

Bring controlled switching into a Simplebus intercom or physical-security system without changing the contact logic required by the connected circuit. The relay presents COM, normally open, and normally closed connections, allowing an installer to choose a contact state that matches an auxiliary device or control input. With support for loads up to 10 A at 12-24 V, it addresses switching duties that need more than a signal-only connection. Comelit 1256 connects that relay function to the Simplebus network, making it appropriate where a network command must operate a door release, gate controller, light, annunciator, or another compatible auxiliary circuit. The contact configuration is especially useful when the target equipment expects either a normally open trigger or a normally closed condition. Select the circuit voltage and load so they remain within the stated relay limits. The unit's defining characteristics are its Simplebus network integration and its COM/NO/NC relay interface, rather than a fixed-purpose output dedicated to one device. That makes the component suited to installations that need one controllable relay point while retaining the connected equipment's preferred contact behavior. It belongs at the interface between a Simplebus control event and the external circuit being switched.
