The CPM1A series micro controllers solve both basic and semi-complex applications. The brick style models include AC inputs/relay outputs, DC inputs/transistor or relay outputs to meet your design requirements. The base I/O for the CPUs ranges from 10, 20, 30, and 40 I/O points with maximum expansion to 100 I/O. Specialized expansion modules include mixed analog I/O, temperature sensor inputs and serial communications.
The CPM1A is a micro programmable controller offered in AC and DC input versions. It supports 10‑40 I/O points natively and can be expanded to up to 100 points with dedicated expansion modules. The controller includes relay and transistor output options, analog and temperature sensor modules, and built‑in communication ports.
This handbook covers general specifications, I/O allocation, analog and temperature sensor modules, communication adapters, the full instruction set, programming guidelines, and data‑exchange connections. It also lists part numbers for peripherals, programming consoles, and software tools such as CX‑Programmer.
