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.
It acts as the central processor, receiving signals from humidity sensors, executing programmed control logic, and sending commands to actuators like humidifiers or dampers to maintain desired humidity levels.
Supply voltage is 24 V DC ±10% per IEC 61131-2, power consumption 10-20 W, digital I/O 8-16 inputs and 6-12 outputs, analog I/O 4-8 inputs and 2-4 outputs. These are reference ranges; confirm with the manufacturer.
Operating temperature -20 to 60 °C, storage -40 to 85 °C, relative humidity 5-95% non-condensing, and ingress protection IP20 to IP65. Verify for the specific model.
