The control inputs (GPI Xa/b) are completely independent and electrically
isolated. They may be used either with the internal +5 V DC supply voltage,
or with external voltages of 5...24 V DC, regardless of the polarity.

The control outputs (GPO Xa/b) are completely independent and electri-
cally isolated relay contacts, closed if active. They may be used either with
the internal +5 V DC supply voltage (VCC) and the internal ground, or with
external voltages within the limits given in the table below. So when using
an external supply, it is irrelevant wheter the load is connected between + or
GND and one of the relay contacts, regardless of the polarity of the external
supply voltage.

The +5 V DC supply voltage and the ground (GND) terminals, together with
the relay contacts, may be used to generate an output signal. Using an external
supply together with the relay contacts is possible as well.
The total current supplied by all VCC (+5 V DC) pins of the GPI / GPO con-
!
nectors must not exceed 400 mA.
