1 company lists this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
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 processor speed is typically in the range of 100–400 MHz, depending on the model. Higher speeds are suitable for complex control algorithms. Always confirm the exact speed for your specific module with the manufacturer.
The module supports RS-232 and RS-485 serial communication interfaces, per TIA/EIA-232/485 standards. These are used for PLC networking and communication with other devices. Verify the exact interface configuration with the supplier.
The module operates in temperatures from -40 to 85 °C (per IEC 60068-2-1/2) and humidity from 5% to 95% RH non-condensing (per IEC 60068-2-78). Ingress protection ranges from IP20 to IP65 (per IEC 60529), depending on the enclosure. Confirm these ratings for your specific model.
The module supports 16–128 digital I/O points and 4–32 analog I/O channels. The exact number depends on the configuration and expansion modules. Check the technical datasheet for your specific CPU module.
