What is COM?
“Common” is an electronics term for an electrical
connection to a common voltage. Sometimes “com-
mon” means the same thing as “ground”, but not al-
ways. In the case of the BLU Servo, 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 +
Note: If current is flowing into or out of an input, the
logic state of that input is low or closed. If no current
is flowing, or the input is not connected, the logic
state is high or open.
User Out 24V supply
The BLUAC5 has a 24 Volt 100 mA isolated output
that can be used for powering Digital Inputs or out-
puts. This convenient power supply can be used in
place of an external supply.
The diagrams on the following pages show how
to connect the inputs to various commonly used
devices.
