Product Details

Danaher Motion M.1300.4981 is an original relay output module and 8-channel relay rack card, a dedicated relay output PCB designed for legacy Danaher Motion MMC multi-axis motion control racks. This plug‑in board integrates eight independent relay output points, including four Form A normally open contacts and four Form C changeover contacts. It receives control commands from the rack master controller and switches external loads such as solenoid valves, alarm lamps, auxiliary contactors and field actuators according to motion interlock logic. As a discontinued original spare part, this relay output module is widely used for the maintenance and retrofit of ageing CNC machine tools and automated production lines. Direct drop‑in replacement can restore all relay switching functions without rewriting the original machine control program, greatly reducing equipment downtime and avoiding costly system upgrades. Built with reliable relay elements, surge suppression circuits and low‑contact‑resistance design, the M.1300.4981 delivers stable switching performance under frequent cyclic operation, even in industrial control cabinets with electromagnetic interference. It serves as a dependable spare relay output card for MMC motion racks.
