Finder offers ultra-slim relay interface modules for industrial applications
Finder
39 Series Master Interface
Finder has introduced the 39 Series Master Interface range of ultra-slim relay interface modules, which incorporate a replaceable fuse for output circuit protection, as well as busbars and terminals that simplify input and output wiring.
These interface modules offer integral coil protection circuitry across the gamut; a secure retention and ejection clip; and terminal screws suitable for blade and crosshead screwdrivers.
Enclosed in a compact 6.22mm package, the module comes in five different types, designed to meet the specific requirements for basic, enhanced, input, output and timer interface functions.
Accessories for the 39 Series relay interface modules include red, blue and black 16-way jumper links, as well as dual-purpose separators (1.8mm or 6.2mm) for the visual or protective separation of groups of interfaces operating from different supply voltages.
Module types
Master Basic
- Available with electromechanical or solid-state relays for general interfacing applications
- Features common link supply terminal positions
- Allows use of a 16-way jumper link
Master Plus
- Offers option for a quick connection replaceable output fuse
- Offers option for a special leakage current suppression
- These help mitigate detrimental effects caused by residual current in the input circuit
Master Input and Master Output
- Incorporate additional busbar jumper links and terminals needed for the full connection of two- or three-wire input devices and output devices
- Finder claims this helps reduce component cost, time and panel space
Master Timer
- DIP-switch selection of four time scales and eight functions
- Features timer delay adjustment, achieved via a rotary knob on the top surface
