ELMON board 31-30
Safety Relais

3. General

The ELMON board 31-30 switching unit, designed with one channel, is used for evaluating safety contact
mats and for safeguarding locations where there is a risk of crushing and cutting through the use of safety
contact edges and safety bumpers (sensors).
The ELMON board 31-30 switching unit is intended for use on plants/machines that make a test signal
available through a primary controller prior to each dangerous movement. In combination with the test
signal, the switching unit satisfies safety category 2 acc. to EN ISO 13849-1:2008 "Safety-related parts of
control systems" .
Monitoring of the standby current is made possible by an integrated terminating resistor in the sensor. If
the specified standby current is flowing, the output relay is activated and the switching contact is closed. If
the sensor is actuated or the sensor circuit is interrupted, the relay switching contact opens. The monito-
ring state of the sensor and the applied operating voltage are indicated by LEDs.

4. Proper use

The ELMON board 31-30 switching unit can only fulfil its safety-related task if used properly.
Proper use of the switching unit is the use as protection in combination with safety contact mats, safety
bumpers and safety contact edges .
Any uses above and beyond these uses constitute improper use. The manufacturer assumes no liability for
damages arising from improper use .
The device may only be used in special applications with the manufacturer's express consent.
