In my earlier post I stated that the incoming battery 12VDC power to our machine was experiencing voltage drop when a large DC motor was started. After more testing we have found the the voltage drops to 8.1 volts. This voltage drop resets the plc. To solve the problem I am trying to source a wide range dc/dc converter with regulated 12VDC output. The only thing I can find in the documentation is to supply a 2 amp power supply. Can anyone advise what the power requirements are if I were to supply regulated power to only the PLC incoming power, the inputs, and the analog supply (for one analog input) on the T100MD16-16+? I have to believe that the PLC power consumption is only a few watts and the inputs woulds be 5-7mA each. The outputs will be fed from the incoming unregulated supply.
Anyone have any idea what size the dc/dc converter should be?
