So I'm installing 4 pumps (in a rather large system) and each will have an HOA switch as well as remote start/stop. I'm torn as to whether I should or shouldn't eat up 4 PLC inputs per station. 1 for Manual, 1 for Auto, 1 for start PB and one for stop PB. I know I can get away without using so many I/O, but what is best practice/Industry standards. Any help?
