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.
Electrical Specifications
Use Parameter P03 (See
Setup Screen 3 (Analog Input Type Select), page 45
)
to select the input signal type.

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).
Electrical Specifications
Use Parameter P04 (See
) to select the output
signal type.
Voltage output mode, P04 = 0
