IN/OUT2 Connector (-SE and -QE only)
The BLUAC5-SE and the BLUAC5-QE have a second DB-25
I/O connector labeled IN/OUT 2. This provides:
8 optically isolated digital inputs IN1 - IN8
4 optically isolated digital outputs OUT1 - OUT4
one 0 - 5 volt analog input, 10 bit ADC resolution
Single Ended Inputs
IN1 - IN6 are single ended, 12 - 24V inputs. They can, as a
group, be configured to accept current sourcing (PNP) signals
by tying one of the COM terminals to the return of the I/O
power supply. If the COM terminals are connected to the + I/O power supply then the inputs
1 - 6 will accept sinking (NPN) signals. 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 me-
chanical 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 Applied Motion.
Differential Inputs
IN7 and IN8 are differential, 12 - 24V inputs. They
can individually be configured to accept current
sourcing (PNP) or current sinking (NPN) signals.
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
.
The diagrams on the following pages show how
to connect the inputs to various commonly used
devices.
