NPN configuration for digital inputs (DIGITAL IN)
Internal and external +24 V power supply connections for NPN configuration are shown in
the figure below.
Connection for obtaining 0…10 V from analog output 2 (ANALOG IN/OUT)
To obtain 0…10 V from analog output AO2, connect a 500 ohm resistor (or two 1 kohm
resistors in parallel) between analog output AO2 and analog common ground AGND.
Examples are shown in the figure below.
