Process safety relays
The PSR-FSP2/2×1 and PSR–FSP/2×1 process safety relays are safe interposing relays specifically designed to operate with fail-safe controls in process applications. The PSR–FSP/2×1 can be used in applications up to a Safety Integrity Level (SIL) 3, and the PSR-FSP2/2×1 can be used for up to a SIL 2 requirement, according to IEC 61508. These process safety relays are compatible with “test pulses” and inrush constraints that occur on safe PLC/DCS outputs. The relays measure just 17.5 mm wide.
