class DInput2Relay1Temp2Module : public Module 

This class represents the Digital Inputs, Power Relay and Temperature Module connected via eMOD bus to controller module. Firstly, this module has 2 independent digital inputs and the status of each one can be obtained separately. If a polling is to be performed more than once per second, it's recommended to handle function call. Secondly, it has 1 power relay that can be activated or deactivated. If a polling is to be performed more than once per second, it's recommended to handle function call. Lastly, it has 2 temperature sensors and the temperature of each one can be obtained separately.
