Interface relays, coupling relays and relay sockets for DIN rail: reliable signal transmission for PLC systems, control cabinets and industrial automation — built for long-term availability.
Including plug-in relays, plug-in and screw sockets, and matching accessories — engineered for long-term stability in control cabinets and control systems.
Every relay and relay socket series for factory automation is developed to CE and UL requirements, making them suitable for worldwide use in control cabinets and automation systems.
Start by comparing the task in the control circuit, the space available and the contacts you need. The series overview narrows down suitable relay platforms; for the specific version, the coil voltage, the load and the matching relay socket are decisive.
ZJ10F is the standard platform for PLC interfaces and general control signals. ZJ14F offers compact versions with 1 or 2 changeover contacts. ZJ41F combines 1 changeover contact with ultra-thin DIN rail sockets for space-saving PLC I/O circuits.
ZJ18F comes in versions with 2, 3 or 4 changeover contacts and socket options with plug-in or screw terminals. Check which contacts must switch together and which connection technology suits the control cabinet.
ZJ115F is intended for control circuits with higher switching currents; ZJ157F also addresses motor loads and interlocking tasks. The series name alone does not determine suitability: the type of load, operating current and switching frequency must match the specific version.
41F and 49F are relay socket series. Match relay, socket and accessories as a combination: contact arrangement, pin assignment, mounting and LED, protection and test options must fit together. Check the compatibility of the specific articles, not just the series names.
