Analog Outputs:
With DLUX303 controllers, there is an analog output signal for temperature, humidity,
and CO2 which represents the actual chamber values. This allows the chamber to be
connected to an in-house data acquisition or alarm system.
The analog signal outputs are selectable as either voltage DC or milliamp. In both
cases, the output is scalable from 0.0 to 20.0. Common settings are 0-1V, 0-5V, 1-5V,
0-10V, 0-20mA, and 4-20mA. The factory default settings are 0-5V.
For each selected output range, a temperature, humidity, and CO2 value must
correspond to the high and low range. This range should be large enough to
encompass the entire chamber possible values and small enough to provide adequate
resolution. The analog outputs can be calibrated by placing an offset into the controller.
This offset affects only the analog outputs and not the controller displayed value. To
change the controller displayed value, see the calibration section in the manual.
To change the factory defaults of the controllers, the controllers must be unlocked.
Refer to Section 14, Unlocking the Controllers.
