Why Choose the Finder 93.66.0.240 MasterPLUS Relay Socket?
The Finder 93.66.0.240 is a compact MasterPLUS push-in terminal relay socket designed for compatible Finder 34 Series electromechanical and solid-state relays. Part of the Finder 93 Series and the MasterINTERFACE system, it provides a convenient interface between plug-in relays and industrial control panel wiring.
Designed for 24–240 V AC/DC control supply applications, the Finder 93.66.0.240 incorporates an integrated LED indicator and EMC suppression circuit. Its screwless push-in terminals simplify conductor installation, while the integrated plastic retaining and extraction clip helps secure the relay and facilitates removal during maintenance.
With a space-saving 6.2 mm housing width, standard 35 mm DIN rail mounting and compatibility with selected Finder 34.51 and 34.81 relays, the socket is particularly suitable for densely populated automation cabinets. Connections for a 16-way jumper link, an optional fuse module and compatible identification accessories provide additional flexibility for professional electrical panel assembly.

Ultra-Slim Relay Interface with Push-In Wiring and Wide-Range AC/DC Control
The Finder 93.66.0.240 provides a compact connection interface between compatible Finder 34 Series plug-in relays and the external control circuit. Its integrated input circuitry supports the specified 24–240 V AC/DC control supply range when paired with an approved relay, while the built-in LED provides visual input status indication.
The integrated EMC suppression circuit helps reduce electrical interference associated with relay control operation. Its screwless push-in terminals allow conductors to be connected efficiently, making the socket suitable for repetitive wiring tasks in industrial electrical panels.
At just 6.2 mm wide, the MasterPLUS socket is especially useful where several relay interfaces must be installed side by side. Compatible 16-way jumper links can simplify common-potential distribution, while the optional Finder 093.63 fuse module provides an additional configuration option for suitable output circuits.
The socket does not independently switch the connected load. The installed electromechanical or solid-state relay determines the output switching characteristics and permissible load. The complete relay interface must be selected and operated within the manufacturer's specified electrical limits.
