System compatibility121-108-306 belongs to MODICON 121 series motion interface module. Compatible with MODICON 984 series CPU,MM series motion processor and MODICON servo drive/motor set. It can be installed in local rack or remote RIO rack. Suitable for machine tool,packaging machinery,textile equipment,automated assembly line multi-axis motion control renovation and replacement as industrial spare part.

Function121-108-306 servo motion control interface module. It transmits command signals from motion processor to servo drive,receives differential encoder feedback signals from servo motor,realizes signal conversion and signal isolation. It monitors encoder signal integrity,detect cable break and signal loss fault. Built-in hardware self-diagnosis for channel status monitoring. Widely used for servo closed-loop motion signal transmission, serving as reliable motion interface spare part.

InstallationCut off rack power and servo power before installation. Insert 121-108-306 module into MODICON backplane slot and lock the card. Check gold finger contact condition. Connect servo command cable and encoder feedback cable to module terminal block. Configure channel parameters,verify signal transmission and complete motion function test before formal operation.
