Phoenix Contact 2903370 RIF-0-RPT-24DC/21 Relay Module, 1 Changeover Contact, 6.2 mm, 24 V DC

Space is often at a premium in control cabinets, yet reliable signal switching remains critical. The Phoenix Contact 2903370 RIF-0-RPT-24DC/21 relay module solves this by packing a robust 1 changeover contact into a slim 6.2 mm housing. This industrial-grade module is engineered for demanding automation environments where every millimeter counts and dependable performance is non-negotiable.

Who is it for

This relay module is ideal for control panel builders, automation engineers, and maintenance technicians who need to switch AC or DC loads up to 250 V and 6 A. It is particularly well-suited for PLC output interfacing, signal isolation, and general switching tasks in industrial machinery, building automation, and process control systems.
