FAQ What is the coil voltage for the relays on this module?The relays on this UMK-8 RELS/KSR-G24/21/PLC module have a nominal input voltage of 24V DC, as indicated by the “G24” in the part number and the specifications of the installed Schrack RP310024 relays. Are the individual relays on this board replaceable?Yes, the eight Schrack relays are plug-in types. They can be individually removed from their sockets on the PCB and replaced if one fails, without needing to replace the entire module. The compatible relay type is Schrack (TE) RP310024 or an equivalent with the same pinout and coil voltage. How is this module typically connected to a PLC?This module is designed as a PLC interface. It can be connected via a flat-ribbon cable to a corresponding PLC output card using the multi-pin connector in the center. Alternatively, individual channels can be wired directly to the screw terminals corresponding to each relay’s coil. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
