    Suppose i use a load which requires only 4mA for a digital on/off, should i require an analog output module of 4 to 20mA for PLC, or can i directly connect it to the PLC digital output module with 2A output.

    Use the digital output. Pay attention to the voltage you supply to your load. Is the digital 2A output a dry contact or is the PLC supplying the output current?
