Npn Configuration For Digital Inputs (X2 & X3); Connection For Obtaining 0 - ABB ACQ580-34 Hardware Manual

WARNING!
Do not connect the +24 V AC cable to the control board ground when the control
board is powered using an external 24 V AC supply.
￭ NPN configuration for digital inputs (X2 & X3)
Internal and external +24 V power supply connections for NPN configuration are shown in

WARNING!
Do not connect the +24 V AC cable to the control board ground when the control
board is powered using an external 24 V AC supply.
￭ Connection for obtaining 0...10 V from analog output 2 (AO2)
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.
