Hello everybody, I'd like to use a Pi as a PLC. I find a lot of developer boards, but didn't find a lot of industrial I/O besides the well known expensive solutions from the big names. The modules should be mounted to DIN rail und wired through RS485 (preferably MODBUS, because it is an open protocol). I'm looking for something like 16 inputs and 16 outputs (relays, 2A inductive load). About 8 to 10 of the inputs should be analog for measuring temperatures with NTC thermistors. Any other bus is acceptable, the distance from the Pi is
