These self-configuring I/O modules are available with four, eight and 16 digital signals that can be used bidirectionally as inputs or outputs. This allows many different applications to be implemented with the same module. The variant with 16 I/O is a suitable alternative to comparable Ethernet or IO-Link-based I/O solutions, and it includes channel-specific diagnostics that provide a detailed overview, even if many inputs and outputs are present. Sensors and actuators can be connected in any combination, with a possibility of two signals per M12 port. An optional assignment of a fixed configuration of the inputs and outputs is possible via company software.
