Hazardous Areas

Intrinsically Safe Relay

Product Overview

The Two-Channel Switch-Operated Relay (ISMTL5526) enables two separate intrinsically-safe (IS) circuits in a hazardous area to be contact controlled by one or two on / off control signals in a safe area.

The output-relay contacts are certified as non-energy-storing apparatus, and can be connected to any IS circuit provided that separate IS circuits are such that they would remain safe if connected together.
