Analog Inputs; Analog Outputs - Graco ProBell Electrostatic Controller Instructions And Parts

Analog Inputs

The analog inputs are used to set certain parameters
remotely by a PLC. The inputs can be configured
to be either voltage or current inputs. This setting
applies to all inputs simultaneously.

Analog Outputs

The analog outputs are used to communicate
actual values to other devices, such as a PLC. The
outputs can be configured to be either voltage or
current outputs. This setting applies to all outputs
simultaneously. The analog outputs require an
external 24 VDC voltage to be connected to Output
External Power (discrete I/O interface, pin 16).
