BIS-411B

Bistable relay

Electronic bistable pulse relay BIS-411B allows switching on or off 

the lighting or other device from several different points by paral-

lel connected, momentary (bell) control switches.

A push button on the housing enables direct control of the cir-

cuit without the need to trigger external buttons.

The receiver is switched on after a current pulse caused by pres-

sing any momentary (bell) button connected to the relay. After 

the next pulse, the receiver will be switched off. The relay does 

not have a "memory" of the contact position, which means in 

the event of a power failure and its  subsequent return, the relay 

contact will be set to "off". This prevents the controlled receivers 

from being switched on automatically without supervision after 

a prolonged power failure. The button on the housing performs 

exactly the same function as the external button connected to 

the terminals of the device.
