• Rear integrated backplane connector and locking mechanism

  Working Principle:

  Field 24 VDC discrete signals enter the module through terminals, pass surge protection and debounce circuits, and are converted into standard digital signals. All channel data are packaged and uploaded to DCS controller through backplane bus, realizing centralized acquisition of massive switch signals.

  Advantages & Highlights:

• Ultra-high channel density greatly saves cabinet space
• Group isolation design balances performance and cost
• Excellent filtering performance adapting to complex field interference
• Software configurable debounce time for different field switch types

  Applicable Industries: Large thermal power units, large chemical complex, metallurgical integrated plant, large-scale water treatment plant

  Model Series: Emerson Ovation High-density I/O Module Series

  Installation Requirements:

• Install on standard Ovation DCS rack vertically
• Reserve heat dissipation space above and below module
• Adopt classified wiring for multi-channel signal lines
• Shielded cable for long-distance signal transmission

  Usage Notes:

• Strictly follow 24 VDC rated input voltage
• Classify wiring to avoid signal crosstalk
• Adjust debounce parameters according to field switch characteristics
• Prevent dust accumulation on high-density terminals
