Okay, everyone, I know this is going to sound like an extremely noobish question. I've spend about a half an hour searching for the answer on the boards already. Anyway...
I am working on designing a machine to dispense pallets. I am using 24V DC control and had been using a 5 Amp power supply. My boss wants to lower hardware costs and has asked me if we can downsize this power supply so now I am actually trying to calculate the load on the power supply.
This machine is controlled by a MicroLogix 1200 (1762-L40BWA), 24 DC inputs, 16 relay outputs. I've already added up my outputs (pilot lights, relays, motor starters) but what I am curious about is if I only need to add the power used by my input devices (photo eyes, proximity sensors) or if I need to also add power used by the input points themselves?
Any help is greatly appreciated.
