1.2 Expansion Modules
CTH200 CPU offers local I/Os, you can also use expansion modules for more additional I/Os and
communication functions. The various expansion modules include digital I/O modules, analog
I/O modules, temperature collection modules and DP communication modules etc. These
modules consist of different I/O number, used for configuring various scale of I/Os with high cost
performance. All modules are installed with standard DIN35 rail.
