The Panasonic AFP7PP04L is a 4-axis motion control module for the FP7 series, carrying one solid-state output for pulse trains or direction signals. It clips onto the DIN rail alongside other FP7 slices and connects via the rectangular I/O header. Rated for 0°C to 55°C ambient, this is the kind of part you keep on the van – it fixes the motion axis where it sits without swapping the whole rack.

Need only 2 axes? The AFP7PP02T shares the same form factor and output but controls two axes instead of four. Saves a few dollars and doesn't waste a slot.
