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.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
