I am looking for a plc card with measuring range: 0 to 10V(DC). But the card should have a voltage protection of minimum 600 Volts(DC) at inputs.
There are cards that offer 200V isolation with the backplane bus. This means that if 200+ DC volts are applied, the CPU does not fry up - but the input card does!
I wonder if it is even possible to get 600V DC protection like this. Can anyone suggest any external devices(transducers/over voltage protection circuits) that I can use with PLC modules. The points to bear in mind are...
1. The process needs highly accurate readings(upto 2 decimal places).
2. Currents up to 13 K amps are flowing in the process (but I am only measuring voltages)
3. I need this info for a Caustic Soda Plant using Membrane technology. Any links or advice related to this industry would be extemely helpful.
Thanks!
