CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The module accepts a nominal input voltage of 24 V DC with a tolerance of ±10%, as per IEC 61131-2. This means the acceptable range is approximately 21.6 V to 26.4 V DC. Operating outside this range may cause false readings.
The module provides 8 to 32 channels, depending on the specific model. Each channel can connect one field device, such as a switch or sensor. The exact number of channels should be confirmed with the manufacturer for the specific variant.
The isolation voltage ranges from 500 to 1500 V AC, as per IEC 61131-2. This isolation helps ensure safety and protects the PLC backplane from voltage transients. Verify the exact rating for your model.
Yes, the input delay is configurable from 0.1 ms to 10 ms. A shorter delay is suitable for high-speed signals, while a longer delay can filter out noise. The specific setting depends on the application requirements.
