The Modbus 4-channel DI/DO module has four independently configurable inputs/outputs. The inputs can be used either as a binary, frequency or counter input with three selectable input levels. The open collector outputs are usable as binary, frequency, pulse or PWM outputs. Various time functions can be used to influence the switching behaviour. All parameters can be set via the Modbus RTU interface. A subset of the settings is available via DIP switches.

The 5-way isolation ensures reliable decoupling of the inputs/outputs from the processing circuit and the power supply. Power supply and Modbus RTU must be connected via the In-Rail-Bus connection (see accessories).
