Finder has launched its new 39 Series MasterINTERFACE range of relay interface modules that feature a replaceable fuse for output circuit protection, plus busbars and terminals that help to simplify input and output wiring. The 39 Series offers integral coil protection circuitry as well as a secure retention and ejection clip, and terminal screws suitable for blade and crosshead screwdrivers.

Available with electromechanical or solid state relays for general interfacing applications, the MasterBASIC features common link supply terminal positions, allowing the use of a 16-way jumper link. The MasterPLUS module adds the option of a quick connection replaceable output fuse and special leakage current suppression versions to mitigate any detrimental effects caused by residual current in the input circuit. Both the MasterINPUT and MasterOUTPUT incorporate additional busbar jumper links and terminals necessary for the full connection of 2- or 3-wire input devices and output devices respectively, thus reducing component cost, time and panel space. The MasterTIMER is a multi-function and multi-range device with DIP-switch selection of four time scales and eight functions.

The MasterADAPTER permits the easy connection of A1/A2 terminals of up to eight MasterINTERFACE modules to PLC outputs via a 14-way ribbon cable, plus simple 2-wire power supply connection, providing wiring savings.
