Moore Industries SRM

The SRM Safety Relay Module is part of the Moore Industries FS FUNCTIONAL SAFETY SERIES. It is exida certified for single use in a Safety Instrumented System up to SIL 2. The SRM is a relay repeater model that accepts a single contact closure input from a logic solver trip output, such as the Moore SPA2 or STA, and provides three contacts per alarm input, allowing you to add alarm contacts for your safety processes without special installation or configuration.


The SRM is built using a safety-rated relay with forcibly-guided contacts. This is unlike traditional multi-output off-the-shelf interposing relays. This design is commonly used in control and safety systems where the logic of an application needs to detect the state of the output contacts. This is achieved by monitoring the state of the monitor contact that is also mechanically linked to the same armature as the output contacts.


A Force Guided Relay avoids the possibility of having contacts stuck in the Normally Open (NO) and Normally Closed (NC) states at the same time. Also known as a Positively Guided Relay, the Force Guided Relay assures users that mechanical
problems such as welded contacts won’t be missed.


The SRM is housed in a DIN case that can be mounted on 35mm Top-Hat DIN-rail. The aluminium housing is more rugged and durable than safety relays housed in a plastic case.
