Safety relay monitors safety of circuits, helps OEMs

Eaton's ESR5 safety relay expands the diversified industrial manufacturer's safety solutions for North American customers. The relay is engineered for OEMs to monitor safety circuits and enhance equipment safety by monitoring the signals from safety devices and switching off quickly in an emergency.


The Eaton is expanding its safety solutions for North American customers with the introduction of the ESR5 safety relay, which is designed to safely monitor safety circuits.Eaton ESR5 safety relay expands diversified industrial manufacturer Eaton Corporation's safety solutions for North American customers. The ESR5 is engineered to monitor safety circuits and will be a key enhancement to the safety of equipment. Already available in Europe, the device is designed specifically for original equipment manufacturers (OEMs).

Richard Harwell, advanced solutions manager at Eaton. “The ESR5 safety relay is engineered to offer a high degree of reliability and safety for plant machinery." He noted that “Eaton provides customers with a range of safety solutions aimed at prevention, protection and preparation.”

The relay monitors the signals from safety devices and switches off quickly in an emergency. With redundant features, it is engineered for the construction of safety applications. The ESR5 is compatible with many safety devices, including emergency stops, rope pulls, two-hand control stations and others. In the event of a fault or activation of the safety device, the enable paths are switched off. The ESR5 detects faults that occur in the control circuit, including ground fault, cross connection fault or wire breakage. It is available in single- and dual-channel versions.

Rated for global applications, the ESR5 safety relay is designed in accordance with European standard (EN) 954-1, International Organization for Standardization (ISO) 13849-1, InternationalElectrotechnical Commission (IEC) 62061 and 61508. The ESR5 also meets Underwriters Laboratories (UL) 508, Canadian Standards Association (CSA) and Conformité Européenne (CE) standards and certifications. It is rated by TÜVRheinland for use in safety applications.

Eaton is celebrating its 100th anniversary in 2011.

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.
