Would you fuse every module in a Point IO system or by groups?
I have 3 Point IO racks and about 30 modules total of assorted IO (DI, DO, AI, AO). Independent fusing would be huge.
Normally I have 1 fuse for inputs and 1 for outputs. I know this makes it a little hard to locate a fault, you usually have to disconnect wires at the terminal strip to find (I use an separate common power wire to each module from the terminal strip).
How would you fuse?
Actually, how do most of you fuse any of your PLC IO modules?
