Safety relays for machine safety applications

Idec HR1S safety relays are designed for machine safety applications and have instantaneous and time delay safety outputs, company said.


UL listed, CSA certified and CE marked, as well as being EN ISO 13849-1 Performance level e (PLe), safety category 4, and EN 62061 Safety Integrity Level 3 (SIL3) compliant, Idec HR1S safety relays are reportedly designed for machine safety applications. 

HR1S safety relays are reportedly predictable and controllable with several variations available including models with instantaneous (STOP 0) safety outputs or with time delay (STOP 1) safety outputs for various machine safety design requirements. Internal safety relays or other operations can be monitored with LED indicator and various auxiliary outputs.

Optional removable terminals reportedly make these safety relays easier to wire, decreasing downtime and the chance of wiring errors when replacing the unit; simply unplug the terminal and plug it into a new relay.
