BIS-412 electronic bi-stable pulse relay is designed for operation in a group configuration.
Power supply 24 V AC. Maximum load 16 A (160A/20ms). On rail TH-35.
A single relay enables the activation and deactivation of the receiver controlled after each current pulse triggered by pushing a local control momentary push-button (bell-push). The group configuration enables the deactivation or activation of all receivers connected to individual relays by means of the central control push-buttons.

Functioning:
Local control
The receiver is activated after a current pulse that is triggered by pushing one optional momentary push-button
belonging to the local control group. The contact of the relay is switched to the 7-10 position. After a next current pulse, the receiver will be deactivated (the contact of the relay returns to the 7-12 position).
Central control
DEACTIVATE ALL - after a current pulse triggered by pushing the momentary push-button
, all receivers will be deactivated (regardless of their status, i.e. deactivation or activation) that are controlled separately by individual relays. The contact in each relay will be switched to the 7-12 position.
