Product details

It's designed to isolate control signals from power circuits in a control panel — typical for PLC output buffering or interposing between a safety relay and a contactor.

The 24 V DC coil is the standard control voltage for most PLC and safety-relay outputs. The single change-over contact (SPDT) handles one signal path — enough for a feedback loop or a pilot load, but not for switching multiple loads independently. The narrow 17.5 mm housing fits standard DIN-rail terminal blocks, so it won't eat up rail space in a dense panel.

Compliance and classification

RoHS compliant since 26 September 2024, REACH candidate-list information is available.
