  • Fast update rate allows quick response to changing control demands in high-speed applications.
  • Outputs are isolated from the backplane to protect against transients and ground loops.
  • Non-volatile memory retains configuration and calibration data without battery backup.
  • Software configuration simplifies setup and changes, reducing hardware handling.

Application Scenarios:

  • Process control systems for modulating control valves and variable-speed drives.
  • Manufacturing and packaging machinery requiring precise analog control.
  • Test and measurement equipment providing stimulus signals.
  • Energy management systems controlling setpoints and actuators.

Performance Parameters:

  • Output accuracy is maintained within tight tolerances for precise control.
  • Low drift and high stability across operating temperature range.
  • Compliant voltage/current outputs suitable for standard industrial loads.

Material and Structural Characteristics:

  • Industrial-grade PCB and components designed for longevity in harsh environments.
  • Robust front connector with screw terminals for secure field wiring.
  • Standard Series 90-70 single-slot module footprint.

Working Principle: The module receives digital values from the PLC CPU via the backplane bus. Each channel has a digital-to-analog converter (DAC) that transforms the digital data into a proportional analog voltage or current signal. The outputs are isolated to protect internal circuitry and improve noise immunity. Installation Requirements:

  • Install into any available slot in a Series 90-70 rack (IC697CHSxxx).
  • Use a compatible 40-pin removable terminal block for field wiring.
  • Ensure proper grounding of the rack and the field device shields to reduce noise.

Usage Notes:

  • Configure output ranges and modes using the programming software before operation.
  • Use shielded twisted-pair cables for analog signals to maintain signal integrity.
  • Verify load impedance compatibility with the selected output ranges to avoid errors.
  • Periodically check calibration if extreme precision is required.
