Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is essential for the following industrial systems and equipment:
| pressure: | N/A (electronic component) |
| other spec: | Humidity: 5% to 95% non-condensing, Vibration: 5-500 Hz at 2G, Shock: 30G for 11ms |
| temperature: | 0°C to 60°C (operating), -40°C to 85°C (storage) |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.

Manufacturer profiles associated with Central Processing Unit (CPU).
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The CPU is the core component that reads input signals, executes the control program, and generates output signals to control industrial equipment. It manages the scan cycle, communication, and diagnostics.
Typical clock speeds range from 1.0 to 2.5 GHz, and core counts from 2 to 8 cores. These values affect processing throughput and parallel task execution, but must be confirmed for the specific model.
Program scan time, typically 0.01–0.1 ms/KB, determines how quickly the CPU can process the control logic. Faster scan times enable more responsive real-time control of industrial processes.
Common protocols include Ethernet/IP, Profinet, and Modbus TCP. These enable integration with HMIs, other PLCs, and SCADA systems. Verify protocol support for the specific CPU model.
