Moore Industries SRM Safety Relay Module

Click2Contact

The SRM Safety Relay Module from Moore Industries is a versatile relay repeater module that has been certified by exida for single use in Safety Instrumented Systems up to SIL2.

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. Unlike many other interposing relays, the SRM is a force guided relay, avoiding the possibility of having contacts become stuck in both Normally Open (NO) and Normally Closed (NC) positions at the same time and avoids potential problems caused by issues such as welded contacts.
