OFF point
In the example shown graphically, the input is considered on at 15 mA.
To consider the input off at 13 mA, set the hysteresis to 2 mA. The input
will be considered off when the value is 2 mA less than the threshold.
Input Type. Program the universal inputs to accept input types NPN, PNP, 10k thermistor, 0 to 10 V, 0 to 20 mA, or
potentiometer. The default setting is 8: NPN raw fast. To set the input type, write the following values to the Input Type
Modbus registers.
0 = NPN
1 = PNP
2 = 0 to 20 mA
3 = 0 to 10 V dc
4 = 10k Thermistor
5 = Potentiometer Sense (DXM150 only)
6 = Not used
7 = Bridge
8 = NPN Raw Fast (default)
Temperature °C/°F.
Set to 1 to represent temperature units in degrees Fahrenheit, and set to 0 (default) to represent
temperature units in degrees Celsius.

Analog Output Parameter Modbus Registers
Modbus Register Analog Output Description
4008 Analog Output 1 0 to 20 mA or 0 to 10 V dc output (I/O board jumper selectable)
Accuracy: 0.1% of full scale +0.01% per °C
Resolution: 12-bit
After changing the jumper position, write the appropriate value to the Modbus
registers to define your analog output to match the setting selected by the jumper.
2 = 0 to 20 mA output (default)
3 = 0 to 10 V output
4028 Analog Output 2
6
Setting Enable Full Scale to 1 sets the ranges to a linear scale of 0 to 65535.
