Digital I/O units serve as the PLC’s interface to achieve fast, reliable sequence control. A full range of units, from high-speed DC inputs to relay outputs, let you adapt CJ1 to your needs.

CJ1 units are available with various I/O densities and connection technologies. Up to 16 I/O points can be wired to units with detachable M3 screw terminals or screwless clamp terminals. High-density 32- and 64- point I/O units are equipped with standard 40-pin ‘flatcable’-connectors. Prefabricated cables and wiring terminals are available for easy interfacing to high-density I/O units.
