XPSAC3721P - 

XPS AC, Single Channel
The XPSAC safety relays are used for monitoring Emergency stop circuits conforming to standards EN/ISO 13850 and EN/IEC 60204-1 and also meet the requirements for the electrical monitoring of switches in protection devices conforming to standard EN 1088/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. To aid diagnostics, the modules have LEDs which provide information on the monitoring circuit status.
