Modicon M340
A compact modular PLC that has become the workhorse of water and infrastructure installations across the region. The rack takes power supply, CPU and a mix of digital, analog and communication modules, so a station cabinet can be built exactly to the I/O count without oversizing. Programming is shared with the M580 in Control Expert, which makes a later migration to an ePAC straightforward.
