I am trying to setup an RTU with solar power and am trying to keep the power consumption low. This will have 3 pieces of equipment that I am trying to match voltages on.
1. The radio can be either 12vdc or 24vdc,
2. The data logger is 12vdc only,
3. And last is the plc which has to be an automation direct slave with a 4-channel 4-20ma input card.
I cannot seem to get a 12vdc powered analog card for the plc and was hoping somebody could help me with this.
I have thought about setting up everything 24vdc and using a 24vdc to 12vdc converter for the radio but thought that this would draw more power. Is this true and does this sound like a good solution?
