Description

ABB DSDX451

Technical Specifications:

  • Input Types: Voltage and Current (e.g., 4-20 mA, 0-10 V).
  • Resolution: High-resolution analog-to-digital conversion.
  • Isolation: Channel-to-channel and channel-to-ground galvanic isolation.

Functional Features:

  • Universal Input Configuration: Software-selectable input ranges for flexible application.
  • Noise Rejection: Advanced filtering to eliminate industrial electromagnetic interference.
  • Sensor Power: Provides isolated loop power for 2-wire transmitters.

Application Scenarios:

  • Precision measurement of temperature, pressure, flow, and level.
  • Closed-loop PID control in chemical and pharmaceutical processes.

Performance Parameters:

  • Accuracy: Excellent linearity and minimal temperature drift.
  • Update Rate: Fast scanning for dynamic process control.

Material Composition & Structural Features:

  • Housing: Rugged industrial enclosure.
  • Terminals: Secure connections with clear polarity markings.

Working Principle:
Conditions raw analog signals through amplification and filtering, converts them to digital values using a high-resolution ADC, and transmits the data to the controller.

Installation Requirements:

  • Use twisted-pair shielded cables for analog signal wiring.
  • Ground the cable shield at the module end only to prevent ground loops.

Usage Precautions:

  • Verify the input range configuration matches the connected transmitter.
  • Avoid routing analog cables parallel to high-voltage power lines.
