ESM Safety relays

PDF

EUCHNER ESM Safety Relays are designed to evaluate connected safety components and reliably turn off hazardous machine functions in the event of an unsafe condition. It will also ensure that the machine cannot be restarted until the unsafe condition is corrected and the module reset. This can be used to protect people, machinery and manufacturing processes. Up to safety category 4 (in accordance with EN954-1) and stop category 0 or 1 (in accordance with EN60204-1) can be achieved with the proper installation. Standard or time-delay expander modules as well as 2-hand control modules are available.
