For emergency stop and switch monitoring. 24V ac/dc. Safety modules XPSAXE are used for monitoring Emergency Stop circuits conforming to standards EN/ISO 13850 and EN/IEC 60204-1. They meet the safety requirements for the electrical monitoring of switches in protection devices conforming to standard EN/ISO 14119. They provide protection for both the machine operator and the machine by immediately stopping the dangerous movement on receipt of a stop instruction from the operator, or on detection of an anomaly in the safety circuit itself.These XPSAXE modules incorporate 3 N/O safety outputs and a relay output for signalling to the PLC and have 2 LEDs to provide information on the monitoring circuit status.
