440R-M23151 Applications

The 440R-M23151 monitors emergency stop and guard interlock circuits that require an extended output delay of up to 30 seconds, typically to let large rotating masses or hydraulic systems run down safely before a secondary supply is switched off. Its three delayed N.O. safety outputs coordinate the delayed stop function with the primary stop. Configure the inputs for single- or dual-channel operation and use monitored reset for higher safety categories. The 45 mm wide housing mounts on standard DIN rail. Confirm the 1.5 to 30 second delay setting against the machine run-down time before use.
