Connecting Analog Outputs
With the analog output feature, the controls are equipped with analog outputs. A set of
terminals are provided on the back of the unit to connect to analog outputs.
Analog outputs provide either a milliamps (4-20mA) or voltage (0-5V) signal output to
represent each of the displayed temperature humidity and H2O2 values. These options
can be used for connection to in-house data acquisition, recorder, or alarm system. The
temperature parameter (only) is adjustable in its scaling and is accessable at the Analog
Output screen.
Parameter Voltage Current Corresponding Value
Temperature 0 – 5 V 4-20 mA 0 – 100 °C (adjustable*)
Humidity 0 – 5 V 4-20 mA 0 – 100 %RH
H2O2 0 – 5 V 4-20 mA 0 – 1000 ppm
*Default range is 0 to +100C. Temperature scale low range is adjustable from -50 to 0C.
Temperature scale high range is adjustable from 1 to 100C.
