The Omron CPM2A-20CDRD CPU unit is designed for efficient control tasks and offers a compact solution with 20 I/O points. This model requires a power supply voltage of 24 VDC and operates effectively within 20.4 to 26.4 VDC. It consumes a maximum of 20 watts, ensuring low energy consumption in various applications.
An inrush current of up to 20 A is supported, and the unit's output capacity is strengthened by an external power supply delivering 24 VDC at 300 mA. Insulation performance is notable, with a minimum resistance of 20 MΩ when tested at 500 VDC. The unit demonstrates strong dielectric strength, sustaining up to 2,300 VAC for one minute between AC terminals and ground for safety against electrical surges.
This CPU unit is designed to handle extreme environmental conditions, proven by its resilience against shock and vibration. It can endure operational vibrations ranging from 10 to 150 Hz with an acceleration of 9.8 m/s², and withstand shocks of up to 147 m/s² in each axis. The temperature range for operation spans from 0°C to 55°C, while it can be stored safely between -20°C and 75°C. It operates efficiently in relative humidity conditions of 10% to 90%, provided that it remains non-condensing.
Memory capabilities include 4,096 words for program memory and 2,048 words for user data storage. The instruction set is extensive, comprising 14 basic and 105 specialized instructions with 185 variations. Execution times are rapid, with the LD instruction executing at 0.64 µs and the MOV instruction at 7.8 µs, ensuring quick processing. It also includes built-in communication ports with RS-232C compatibility, supporting host link and various protocols for effective communication.
