Information about the product

The XPSUAK safety relays / safety switchgear protect the operator and the machine by immediately stopping the hazardous movement after receiving a stop command from the operator or by detecting a fault in the safety circuit itself. The XPSUAK can monitor the following protective devices:

Emergency stop circuits according to ISO 13850 standards

Switches activated by protective devices according to ISO 14119 standards:

Mechanical safety switches (position switches, emergency pull-wire switches, etc)

Magnetic switches with antivalent or 2 NC contacts

Proximity switches with antivalent contacts

Pair of sensors

1 PNP + 1 NPN sensor

RFID safety switches

Type 4 light curtains according to IEC 61496-1, which have semiconductor safety outputs with test function

4-wire safety mats or safety edges in accordance with ISO 13856

The required safety function (1 of 10) can be selected and the start function (automatic, manual, monitored, startup test) can be configured via the selector switches on the front. The diagnostic output transmits extensive status information for simplified maintenance and service via a coded telegram to the standard input of a PLC, which processes it further by means of a function block for common control systems. To monitor a higher number of antivalent contacts with this safety monitoring module, the antivalent contacts can be connected in series with a normally closed contact (NC) and in parallel with a normally open contact (NO). Six front LEDs provide information on the status of the monitoring circuit.
