Connecting Communications & Analog Outputs
This unit comes standard with features such as RS485 communications and analog
outputs. A set of terminals are provided to connect to RS485 communications and
analog outputs.
Analog Outputs
Analog outputs are either milliamps (0-20mA, 4-20mA) or voltage (0-5V, 1-5V, 0-10V,
0-20V) signal output that represents each of the displayed temperature (and humidity)
values. These options can be used for connection to in-house data acquisition,
recorder, or alarm system.
Factory default settings are as follows:
Parameter Analog Output Corresponding Value
Temperature 0 – 5 V -50 – 100 °C
Humidity 0 – 5 V 0 – 100 %rh
Connect shielded wires to the appropriate signal terminals: I(+) for current (mA) or V(+)
for voltage (DC). For both current and voltage outputs, COM(-) is common terminal.
The controller itself must be programmed for the voltage or current signal and
corresponding scale (see Operations Section)
