UM-RM104-01 relay module is suitable for Mitsubishi, Fanuc and other numerical control system relay board, using 1C contact, the control signal can be used 0V effective (common positive pole connection) or 24V effective (common negative pole connection) for control, suitable for NPN type or PNP type controller, because it contains rectifier bridge, no need to jump line to achieve two kinds of switching.
This manual describes the UM-RM104-01 relay module, which is compatible with Mitsubishi, Fanuc and other CNC systems, as well as generic FLC and PC‑BASE controllers. It outlines the module’s internal relay circuits, input voltage requirements, and environmental limits.
The document includes wiring diagrams for both common‑negative (PNP) and common‑positive (NPN) signal configurations, physical dimensions for PCB and mounting, and precautionary guidelines for safe installation and operation. This manual is written in Chinese.
