ELMON relay 31-31
Safety Relay

3. General

The ELMON relay 31 switching unit, designed with one channel, is used for evaluati ng safety contact mats and for
safeguarding locati ons where there is a risk of crushing and cutti ng through the use of safety contact edges
and safety bumpers (sensors).
The ELMON relay 31 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 combinati on with the test signal, the
switching unit sati sfi es safety category 2 acc. to EN ISO 13849-1:2015 "Safety-related parts of control systems" .
Monitoring of the standby current is made possible by an integrated terminati ng resistor in the sensor. If
the specifi ed standby current is fl owing, the output relay is acti vated 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 operati ng voltage are indicated by LEDs.

4. Proper use

The ELMON relay 31 switching unit can only fulfi l its safety-related task if used properly.
Proper use of the switching unit is the use as protecti on in combinati on with safety contact mats, safety
bumpers and safety contact edges .
Any uses above and beyond these uses consti tute improper use. The manufacturer assumes no liability for
damages arising from improper use .
The device may only be used in special applicati ons with the manufacturer's express consent.
