PACIO MODULES
108 Parker Automation Controller Installation Guide
NOTE: The PACIO-442-02 made minor changes in approximately January 2017. The modules can be
interchangeable without changing the device description file in the control program of the
EtherCAT Master.
Terminals
Power Supply to Module I/Os
L+ 24 VDC
L- 0 V
Status LEDs
The LED labeled "EtherCAT Run" indicates the state of the EtherCAT ASIC. The LED labeled "IO" indicates
the state of the Module inputs and outputs. The LED labeled "Power" indicates the state of the
I/O power supply.

Measuring range ± 20 mA
Measuring Range
In order to use the current outputs, the
"Chann 1_Unipolar" variable of the
corresponding outputs must be set to True. See
Analog Voltage Values
Short Circuit is detected
Short circuit is not detected, but outputs are
protected against a short circuit
Data-type of the outputs: INT
Data-type of the outputs UINT.
In the development environment, a data type
conversion from INT to UINT is required.
