PLC for small-machine control with relay outputs
The Panasonic AFP0RC10MRS is a compact FP0R-series PLC with 6 digital inputs and 4 relay outputs, running on 24VDC with RS-485 communications built in. The relay outputs handle inductive loads like small contactors or solenoid valves without external snubbers on each channel — useful for panel builders who want to keep the BOM tight. Memory is 12K words, expandable up to 3 additional modules via the backplane bus.
What the I/O mix means for your panel
Six digital inputs (sink/source configurable) and four relay outputs give you enough I/O for a small machine station: start/stop, two limit switches, an encoder gate, and four discrete loads. The relay outputs are rated for 2 A per point (resistive), so they can drive contactor coils or pilot lights directly. No transistor output protection needed — relays isolate the load from the CPU.
Communications and expandability
RS-485 port supports Modbus RTU or proprietary Panasonic protocol for linking to an HMI or SCADA. The CPU can drive up to three expansion modules — mixed I/O, analog, or temperature — without a separate power supply module for the bus. This keeps the DIN-rail footprint small for retrofit panels where space is tight.
