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.
