Design considerations

The CO2101 is a low cost way to input CO2 information into a PLC, process control meter, distributed control system (DCS), SCADA, or other industrial control system. The CO2101 can be wall mounted and connected via instrumentation cable to almost any control or monitoring system that takes analog signals. 

Because the CO2101 has a plastic housing,  care should be taken to insure that the operating environment does not get so hot that the housing will soften. This may happen at temperatures around 180 to 190 degrees F.

The CO2101 should not be used as the sole sensing element in critical equipment or safety applications.
