3 CONNECTIONS
3.1 DIGITAL INPUTS
The 10 insulated digital inputs must be excited by an external source of 24 Vdc. The
inputs are bidirectional, which means the input common can be connected to either
the GND or the VDC of the supply.
The DIs 9 and 10 are faster and can read a signal of up to 100 kHz, and they can also
operate as encoder input. The other DIs can count up to 4 kHz.
