"It has a large choice of number of contacts for high rated current use with space-saving design which allows for a flexible and easy installation on DIN rail." "It helps to reduce the size of enclosures and increase machine reliability, you can mount nearly everywhere." "It is compatible with plug in control relay." "It enables easy installation and connect to relay from its socket." "Workability for hard-wired logic automated systems to complement the functions of industrial programmable logic controllers (PLCs)." 0 0 0 0 0 0 0 0 0

Features

Precision-engineered for the Schneider Electric Zelio RSB series, this 2-pole interface socket provides a perfect mechanical and electrical match for 12A and 16A sub-miniature relays. Using a dedicated, manufacturer-approved base ensures optimal pin alignment and contact pressure, preventing the high-resistance connections and intermittent signal loss common with generic third-party mounting.
Featuring a "separate" contact arrangement, this socket isolates the input (coil) terminals from the output (contact) terminals on opposite sides of the block. This logical, intuitive layout allows for cleaner wire routing and significantly reduces the risk of cross-wiring errors during high-density panel builds, making it an ideal choice for complex automation and PLC interface applications.
Designed for maximum flexibility, the RSZE1S48M snaps instantly onto standard 35mm DIN rails for rapid industrial deployment or can be panel-mounted via integrated screw holes. This dual-mounting capability allows technicians to standardize on a single socket model for both modern rail-based control centers and legacy machine retrofits, streamlining inventory and reducing installation labor
Rated with IP20 ingress protection, this socket features recessed screw-clamp terminals that prevent accidental finger contact with live electrical circuits. This safety-first design ensures your control panels remain compliant with OSHA and IEC 60529 standards, protecting maintenance personnel from shock hazards while maintaining a compact, professional-grade footprint.
