Micro PLCs with an RS-232C Interface
The CPM2A is equipped with an RS-232C interface so a PT can be connected to easily perform tasks such as monitoring a machine's operating rate or making temperature settings. The PLCs are equipped with functions, such as simple positioning (by the pulse I/O function), that allow advanced functionality and high value to be added to compact equipment. Maintenance has been made easier with features such as removable terminal blocks. CPM1A Expansion I/O Modules and Special I/O Modules, such as Analog I/O Modules, can be used.
