SPA2IS facingright ppQ: I need a relay with a SIL 2 rating. Does your SPA2 have a SIL 2 rating?

A: The SPA2 is a SIL 2 capable alarm trip with four process relays that can be used in SIL 2 loops.  The SPA2 has an FMEDA (Failure Modes, Effects and Diagnostics Analysis) report that can be used by a safety practitioner to ensure its applicability in the SIF (Safety Instrumented Function).
