3. General information and functional description
The compact and easy-to-install safety relay is designed for outdoor use and can be operated with 230 V
mains voltage or 24 V AC/DC.
The switching unit, designed with two channels, is used for evaluating safety contact mats and for safegu
-
arding locations where there is a risk of crushing and cutting through the use of safety contact edges and
safety bumpers .
The switching unit complies with EN ISO 13849-1:2015, Cat. 3. To meet Cat. 3 requirements, the switching
unit has a redundant structure with two, two-way polling, forcibly actuated safety relays per channel.
Two separate sensor circuits can be connected to the switching unit, whereby each acts on one switching
output .
The monitoring state of the sensor and the applied operating voltage are indicated by LEDs.
If an error is present, all the safety outputs are not active.
4. Proper use
The switching unit can only fulfil its safety-related task if used properly.
The switching unit is intended to be used as protection in combination with safety contact mats, safety bumpers
and safety contact edges with 8.2 kΩ resistor for standby-current monitoring.
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.
