The C20-CPU44-E, part of Omron's CVM1 series, is an advanced programmable logic controller (PLC) intended for automation systems. It features 16 input points and 14 output points, although the relay outputs are limited to 12 channels divided as 8/3/1 points per common terminal.

This device accommodates a maximum of 1194 addresses for both RAM and EPROM if expanded. However, in a non-expandable configuration, it supports 512 addresses in RAM alongside 1194 in EPROM. The processing speed is set at a typical rate of 10 microseconds for each address, ensuring efficient operations. Each instruction is structured with a length of 6 bytes.

Programming is executed through ladder logic, a method commonly preferred for its ease of use in control system design. The primary components include an MPU, CMOS, and LS-TTL, addressing the requirements of various control tasks.

Power requirements for this module range from 100V to 120V AC. A tolerable operating voltage of 24V DC, with a tolerance of +10% and -15%, guarantees stability. It consumes about 7mA under typical input conditions of 24V DC, with an input resistance measured at 3kΩ. The system employs a programmed storage approach for its control methods, making it suitable for a wide range of industrial applications.
