440R-N23129 Applications

This single-function safety relay monitors emergency-stop buttons, gate interlocks and other dual-channel safety devices, energising three normally-open safety outputs only when the input circuit is intact and a monitored manual reset is performed. The extra normally-closed auxiliary contact reports status to a controller. Fixed screw terminals suit permanent panel installations where a wired device is preferred over a pluggable one. It is applied on machinery guarding, conveyor and press safety circuits requiring a compact, reliable stop function that meets recognised safety categories.
