A set of relay contacts is provided at the rear of the incubator that allows the incubator to output analog signals representing the temperature, CO2/ O2 content and relative humidity, depending on the options available inyour incubator. This allows the chamber to be connected to an in-house data acquisition or alarm system. This option can also be field-installed.

The analog signal outputs can be set to operate in either voltage DC (0-5 Vdc) or current (4-20 mA) mode. The factory default setting is voltage. Switch on the board to toggle between the modes.
