Bistable relay BIS-412 BIS-412

The BIS-412 electronic bistable impulse relay is designed for group operation. A single relay allows  for switching on and off the controlled receiver after each current impulse caused by pressing the momentary (bell) button of the local control. The group system allows you to turn off or turn on all receivers connected to individual relays with the central control buttons.
 Operation:

ON  ALL - after  current pulse caused by pressing the momentary button    all receivers will be switched on (regardless of their status - off or on) individually controlled by individual relays. The contact in each relay will be switched to position 7-10. BIS-411 230V can work with illuminated switches.
