Hi guys,
I am new on this forum so dont be too harsh on me. I am currently working on a little project an i need some help. I wanna thank everyone in advance for any input, advice or guidence. My question is:
I have ten DC circuits coming into a combiner box. Each with its +ve and -ve lead wires. The current in these circuits is typically 4-6 Amps and the voltage is typically 600 V DC or less. My challenge is to monitor each of the currents in the +ve leads with the least cost. The way i am monitoring right now is.. I have a DC current transducer around each circuit; however, it will be really expensive if i wanna monitor 12 or 24 circuits at the same time. Can you think of a clever way where we can accomplish the function of monitoring intermittently each incoming circuit with a limited number of transducers? Is there a circuit switching mechanism that I can buy or design to reduce the number of trunsducers? If I will be able to monitor every incoming circuit just once a minute that is adequate. Even once every five minutes is adequate. I already looked into multiplexers with some kind of timing mechanism but couldnt find any....
Sorry for such a long question. I honestly will appreciate any help/advice you guys can give me. Thanks
