  Working Principle:

  The DCS controller sends digital control values to the module through the backplane bus. The internal DAC circuit converts digital signals into standard analog current signals. After amplification and isolation, signals are output to field regulating valves, frequency converters and other execution units to realize automatic process regulation.

  Advantages & Highlights:

• Ultra-high output precision ensuring accurate process control
• Complete overcurrent and short-circuit protection to protect field devices
• Low temperature drift, stable performance under wide temperature variation
• Compact structure, high integration saving cabinet space

  Applicable Industries: Power plant, chemical processing, oil & gas, pharmaceutical industry, papermaking, light industry automation
