Push-In Relay Connections for Three-Pole Industrial Control Applications
The Finder 94.P3SMA provides the electrical and mechanical connection interface between a compatible Finder 55.33 plug-in relay and the external control circuit. Its 11-pin arrangement accommodates the relay coil and three changeover contact circuits, allowing the installed relay to control multiple auxiliary switching functions.
The screwless push-in terminals simplify conductor installation, while the socket's removable relay interface supports maintenance without disturbing the fixed wiring. The included 094.71 metal retaining clip helps keep the installed relay securely positioned during normal operation.
For applications requiring additional functionality, compatible Finder 99.02 indication and EMC suppression modules and 86.30 timer modules can be selected separately. Compatible jumper links also support efficient distribution of common electrical potentials across adjacent relay sockets.
The socket itself does not independently perform electrical switching or timing functions. These functions depend on the compatible relay and any additional module installed. The electrical ratings of the complete assembly must be respected, including the limitations of the relay contacts and connected load.
