Structural Features: The unit features a compact 35mm width design. The front panel includes a detachable terminal block for field wiring and settings for range selection.

Working Principle: The unit receives digital data from the CPU via the backplane. This data is converted into precise analog signals (voltage or current) by high-speed DACs. The analog signals are then output to control external devices.

Installation Requirements:

  • Mount on CS1 series CPU rack or expansion rack.
  • Connect field wiring to the detachable terminal block.
  • Use shielded cables for analog signals to reduce noise.
  • Separate analog signal cables from power lines.

Usage Notes:

  • Verify the output signal range matches the connected device.
  • Ensure the load resistance is within the permissible range.
  • Do not short-circuit current outputs.
