The Safety Relay Module (SRM) is said to be a versatile relay repeater module that has been certified by Exida for single use in safety-instrumented systems (SIS) up to SIL 2. The SRM is part of the company’s FS Functional Safety Series and accepts single-contact closure inputs from logic-solver trip outputs, including the 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. — Moore Industries International, Inc., North Hills, Calif.
