Applicable Industries

Installation Requirements

1. Secure module to standard 35 mm DIN rail inside IP54 industrial control cabinet
2. Separate Profibus shielded bus cable from high-power AC motor drive wiring with 10 cm clearance
3. Set station address dial switch before powering on the module to avoid bus address conflict
4. Connect module power ground terminal to cabinet protective earth copper bar

Operation Precautions

1. Do not connect AC voltage signals to 24 VDC digital input channels, permanent channel chip damage occurs
2. Adjust input debounce filter time according to field switch mechanical bounce characteristics
3. Avoid installing module adjacent to high heat generating servo drive power modules
4. Power off module before modifying station address dial switch setting
5. Keep cabinet internal ambient humidity below 90% RH non-condensing continuously
