Accessory - KH KHA6-SH-Ex1
switch amplifier for limit switches with inductive contacts, in safety circuit – intrinsically safe
This switch amplifier is suitable for intrinsically safe applications. The device transmits binary signals of SN / S1N proximity sensors from potentially explosive areas to safe areas. To ensure safe operation, the device has an additional protective circuit.
The proximity sensor or the switch controls a safety output with three normally open contacts (one in series with both output relays for the safety function), a standard output with one normally open contact and an error message output with one normally open contact. Line breaks and line short circuits of the inputs are constantly monitored. In the event of a fault, the fault output is activated while outputs I and II drop out.
