Moore Industries SRM/CC/3RO/24DC [DIN] | SRM Safety Relay Module | SIL 2/3 Capable, Contact Closure Input, 3 Force-Guided Relay Outputs
The Moore Industries SRM is a SIL 2/3 capable relay repeater from the FS Functional Safety Series, certified by exida to IEC 61508. It accepts a single contact closure from a logic solver trip output such as the STA or SPA2 and provides three force-guided relay contacts, so alarm contacts can be added to safety processes without special configuration. It is powered from 24 Vdc and mounts on a DIN rail.
Key features
- exida certified to IEC 61508 for single use in a SIS up to SIL 2 and redundant use up to SIL 3
- Safety-rated force-guided relay with a mechanically linked monitor contact
- Three fuse-protected relay outputs per contact closure input
- Front panel LEDs show power, input and output status
- Input snubbing diode in the contact closure circuit
- 1500 Vrms isolation between power and input, each output and case
- DIN-rail mounting on 35 mm (EN50022) Top Hat rails
