6
Temp °C
Celsius, high resolution. Analog input for temperature devices such as thermocouples, RTD, and
thermistors. In high resolution mode, temperature = (Modbus register value) ÷ 20.
LCD: 0000.0C
7
Temp °F
Fahrenheit, high resolution. Analog input for temperature devices such as thermocouples, RTD,
and thermistors. In high resolution mode, temperature = (Modbus register value) ÷ 20.
LCD: 0000.0F
8
Temp °C (Low
Res)
Celsuis, low resolution. To measure a greater temperature range, use the low resolution unit. In
low resolution mode, temperature = (Modbus register value) ÷ 2.
LCD: 0000.0C
9
Temp °F (Low
Res)
Fahrenheit, low resolution. To measure a greater temperature range, use the low resolution
unit. In low resolution mode, temperature = (Modbus register value) ÷ 2.
LCD: 0000.0F

Asynchronous
Counter, 32-
bit
The 32-bit counter value records counts up to 4.29 billion.
LCD: 0000 0000
11
Asynchronous
Counter, 16-
bit
The 16-bit counter value records counts up to 65535.

0
Raw
Displays the raw A/D conversion data with data ranges from 0 to 65535. This units type is
typically used only for factory calibration.
LCD: Raw A/D hex value
1
4 to 20 mA
Analog unit. Modbus register contents are scaled such that 0 represents 4 mA and 65535
represents 20 mA.
LCD: 4.00mA–20.00mA
2
0 to 20 mA
Default analog input unit. Modbus register contents are scaled such that 0 represents 0 mA and
65535 represents 20 mA.
LCD: 0.00mA–20.00mA
3
Discrete (ON/
OFF)
Default discrete unit.
LCD: ON/OFF
4
0 to 10V
(Volts)
Analog unit using 0 to 10V instead of current. Modbus register contents are scaled such that 0
represents 0V and 65535 represents 10V.
LCD: 0.00V–10.00V
