Connecting Inputs and Outputs to IN/OUT2
The IN/OUT2 connector is present as standard on the Si version of the drive. It is also standard on the QE
version. Q versions can have the IN/OUT 2 connector board added at a later date , converting the drive to a
QE version.

Digital Inputs
Single Ended Inputs
The STAC6 includes single ended, optically isolated input circuits that can be used with sourcing or sink-
ing signals, 12 to 24 volts. The IN/OUT 2 connector has 8 of these inputs (IN1 - IN6). These inputs allow
connection to PLCs, sensors, relays and mechanical switches. Because the input circuits are isolated, they
require a source of power. If you are connecting to a PLC, you should be able to get power from the PLC
power supply. If you are using relays or mechanical switches, you will need a 12-24 V power supply. This
also applies if you are connecting the inputs to the programmable outputs of another Si product from Ap-
plied Motion.
What is COM?
“Common” is an electronics term for an electrical connection to a common voltage. Sometimes “common”
means the same thing as “ground”, but not always. In the case of the STAC6, if you are using sourcing
(PNP) input signals, then you will want to connect COM to ground (power supply -). If you are using sinking
(NPN) signals, then COM must connect to power supply +.
