ABB Safety Relays | ABB Jokab Safety Relay

<:contentReference[oaicite:0]{index=0} safety relays are control devices used to monitor safety functions and ensure machinery stops safely during hazardous conditions. They process input signals from emergency stops, safety door switches, light curtains, or two-hand controls, evaluating status using redundant logic to switch safety-rated outputs that remove power from actuators when unsafe states are detected. Selection is based on safety function type, required performance level or safety integrity level, input device compatibility, number of safety channels, output contact configuration, response time, supply voltage, diagnostics capability, mounting method, and compliance with functional safety standards. ABB safety relays are safety-rated electromechanical or electronic control modules, DIN-rail mounted in structure, classified by SIL and PL capability, interfacing through redundant safety inputs and force-guided output contacts to integrate with standardized industrial machine safety architectures.
