Product details

RoHS compliance is confirmed effective 26 September 2024. REACH Article 33 information is available per the current candidate list.

At 6.2 mm wide, this coupling relay fits tightly on a DIN rail — you can pack multiple units in a small enclosure footprint. The screw terminals accept standard control wiring; strip length and torque follow Siemens standard practice for the SIRIUS terminal block family. The 24 V AC/DC coil means it works on either supply type, simplifying panel design where both AC and DC control voltages may be present. The single change-over contact handles signal-level switching or light pilot duty up to the 6 A thermal current limit.
