I/O Module Table
 Currently there are three types of modules;
The E Series Modules which use common environmental probes.
The G Series Modules which are general purpose modules.
And the C Series Modules which are custom designed for particular applications.

More modules are being added to the list. In addition, specialized modules can be built and interfaced with the controllers as needed.

(* any analog input can be used for the light sensors)  


1. All digital inputs are opto-isolated (5-24V AC or DC).
2. All digital outputs are opto-isolated 100 mA relay drivers.
3. Analog input ranges are determined by resistor values, which are set at the factory. Any analog input can be used as an input for iNetGrow Solar Probes.
4. The TCT module uses K-type thermocouples.
