Moore Industries has released the SRM Safety Relay Module, a versatile relay repeater module that has been certified by exida for single use in Safety Instrumented Systems up to SIL 2. The SRM is part of the Moore Industries’ FS FUNCTIONAL SAFETY SERIES and accepts single contact closure inputs from logic solver trip outputs including Moore Industries’ STA Safety Trip Alarm and the SPA2 Programmable Limit Alarm Trip. With three contacts per alarm input, the SRM allows for the addition of alarm contacts to safety processes without special installation or configuration. The SRM has been developed following the IEC 61508 standard and offers a high level of availability for safety-critical applications and for use as a component part of Safety Instrumented Systems (SIS). While most safety relays are in a plastic case, the SRM in housed in a durable and rugged “universal” aluminum DIN case that can be mounted on either a 32mm G-type or 35mm Top-Hat DIN-rail.
