KPM KB2 with +24 VDC + power supply

Relays are of dry contact types. In normal operation the “Break Out On” relay is open and it closes

during a break. In case the power is lost or turned off the “Break Out On” relay remains open

(disabled). “Break Out Off” works in the opposite way. There is 2 parallel Break Relays, Break Out

1 and Break out 2 which are working simultaneously.

”Alarm Out Off” is normally closed. It opens in case the built-in self-diagnostics detects a failure.

If power is lost or turned off the “Alarm Out Off” is OPEN. “Alarm Out On” works in the opposite

way. There is 2 parallel Alarm Relays, Alarm Out 1 and Alarm out 2 which are working

simultaneously.

Fiber optic cable is connected to the optics block. It does not matter which one of the two cables

is connected to the receiver inlet (Rx). In a normal application another cable is connected to the

RGB light source. IR light source is used in special cases such as heavy steam environment or in

an application where exceptionally strong light is needed.
