  • High‑precision calibration and enhanced EMC design meet the stringent accuracy and reliability requirements of complex process control.

Application Scenarios

Widely used in industrial automation projects based on AutoMax and DCS 5000 systems, covering steel, chemical, power generation, papermaking, water treatment, and other industries. It is especially suitable for process control loops that require high‑precision isolated analog output to drive regulating equipment, such as precision flow control, pressure regulation, and temperature control scenarios with high electrical noise or wide temperature fluctuations.

Operation and Maintenance Instructions

  • Before installation or removal, disconnect the system power to avoid electric shock or module damage.

  • Insert the module into the designated slot of the AutoMax rack, ensuring reliable connection with the backplane.

  • Connect field cables to the corresponding terminals in strict accordance with the wiring diagram, and check the polarity to avoid wrong connection.

  • The operating environment should be kept clean, dry, and well‑ventilated, avoiding dust, moisture, and corrosive substances.

  • Regularly check whether the terminal connections are loose and whether the status LEDs are normal.

  • Do not disassemble or modify the module without authorization;internal components are not user‑serviceable.

  • In case of a fault, replace it with the same model in time to ensure uninterrupted system operation.
