Appendix 7 / Analog Inputs and Outputs
This appendix describes how to configure the MICRO 4000 NET controller’s analog inputs and
outputs.
The MICRO 4000 NET controller has two analog inputs and two analog outputs:
Terminal
Terminal
Description
Number
Name
J8-1 +5V REF +5 volt reference output. Connect to end terminal of potentiometer.
J8-2 ANALOG IN+
Analog input, non-inverting. Connect to potentiometer wiper, or
output terminal of sensor or other device.
J8-3 ANALOG IN- Analog input, inverting. Typically not used – connect to SIG GND.
Analog
Input 1
J8-4 SIG GND
Ground reference. Connect to end terminal of potentiometer, or
ground terminal of sensor or other device.
J5-8 +5V REF Connect to end terminal of potentiometer.
J5-9 ANALOG IN
Analog input, non-inverting. Connect to potentiometer wiper, or
output terminal of sensor or other device.
Analog
Input 2
J5-10 SIG GND
Ground reference. Connect to end terminal of potentiometer, or
ground terminal of sensor or other device.
J8-6 ANALOG OUT Analog output. Connect to input terminal of other device.
Analog
Output 1
J8-7 ANALOG REF Ground reference. Connect to ground terminal of other device.
J6-7 ANALOG OUT Analog output. Connect to input terminal of other device.
Analog
Output 2
J6-8 ANALOG REF Ground reference. Connect to ground terminal of other device.
Eleven parameters control the scaling and destination of the input signals and two parameters
select the source of the output signals. Refer to page 17 for more information about setting
controller parameters. The general procedure for configuring the analog I/O is as follows:
1. Set the Analog Input Range (parameter 41 or 42).
2. Calculate and set the Analog Input Scale Factor (parameters 43 and 44, or 45 and 46).
3. Set the Input Type (parameter 12 or 13).
4. Set the Input Polarity (parameter 3 or 4).
5. Set the Analog Offset (parameter 40).
6. Set the Analog Output (parameter 38 or 39).
There are several examples on the following pages that show how to calculate the Analog Input
Scale Factor.
