Digital inputs
If the digital inputs are not supplied with the internal supply voltage of X6-2, Pin 1 (P24OUT), this
supply voltage can optionally be replaced with an external power source (+24 VDC, 1 A
maximum).
The reference ground (GND) of the external power supply source must be connected with X6-2,
Pin 12. X6-2, Pin 1 (P24OUT) remains open.
Specification of the supply voltages (+24 VDC)
The external supply voltages for the ADI4 module, the digital outputs, and optionally the digital
inputs must comply with the specifications provided in the "Encoder supply voltages" table.

External supply voltage
The external supply voltages must each be generated as functional extra-low voltage with safe
electrical isolation (DIN EN 60204-1, PELV).
