Reliable Three-Changeover Relay Connections for Industrial Control
The Finder 94.03SPA relay socket provides a dependable connection between compatible plug-in relays and industrial electrical wiring. Designed for the Finder 55.33 relay, its 11-pin arrangement accommodates three changeover contact circuits and the relay coil connections. This makes it particularly useful where a single relay must control multiple electrical signals or switching functions.
When a compatible Finder 55.33 three-pole changeover relay is installed, each contact set provides a common, normally open and normally closed connection. These contacts can be used for control circuit interlocking, equipment status signalling, auxiliary switching and other applications requiring multiple relay outputs. The actual permissible switching load must be determined from the installed relay's electrical ratings and the characteristics of the connected load.
The socket's box-clamp screw terminals provide secure conductor termination, while its 35 mm DIN rail and panel mounting options give installers flexibility when designing electrical control cabinets. The SPA designation identifies the version supplied with a plastic retaining and release clip, allowing the relay to be secured firmly during operation and removed conveniently during maintenance.
For installations containing several relay sockets, the compatible Finder 094.06 6-way jumper link can simplify common electrical connections where the wiring arrangement permits. The optional identification tag also helps technicians label relay circuits clearly, supporting efficient commissioning, fault finding and future maintenance.
