3.4 RAD-DI4-IFS - digital extension module with four
inputs
The digital RAD-DI4-IFS I/O extension module can process up to four input signals. The
digital inputs process voltages between 0 V ... 50 V AC/DC at the low-voltage input and
voltages between 0 V ... 250 V AC/DC at the high-voltage input. All inputs are electrically
isolated from one another, from the supply voltage, and from the electronics.

WARNING: Risk of electric shock
Use the same phase for digital inputs and digital outputs. The isolating voltage between
the individual channels must not exceed 300 V.
