ABB AI830 3BSE008518R1 S800 I/O 8-Channel RTD Input Module

Product Overview

The ABB AI830 (3BSE008518R1) serves as a high-precision analog input interface specifically engineered for industrial temperature monitoring. This module interfaces directly with Resistive Temperature Detectors (RTDs) to provide accurate thermal data to the controller. By performing linearization and temperature conversion internally, the AI830 offloads processing tasks from the CPU and ensures highly reliable readings. We provide this module as 100% brand new, original factory equipment, ensuring maximum stability for your S800 I/O architecture.

Engineering Advantages

• Internal Signal Linearization: The module converts raw resistance values into standardized temperature units (Celsius or Fahrenheit) internally. This eliminates the need for complex scaling blocks in your control software and reduces overall system latency.

• Superior Lead-Wire Compensation: The 3-wire connection configuration actively compensates for cable resistance. This feature allows for long cable runs between the sensor and the I/O cabinet without degrading the accuracy of the 14-bit resolution.

• Advanced Fault Detection: The AI830 continuously monitors every channel for hardware anomalies. It detects open circuits, short circuits, and grounded sensors immediately, triggering system alarms to prevent incorrect process actions based on faulty data.

• Industrial Hardening: The robust mechanical design handles the vibrations and thermal fluctuations common in motor control centers and process plants. Its groupwise isolation protects sensitive internal electronics from field-side electrical surges.

FAQs

• Which RTD types does the AI830 support?

  The module supports Pt100 (IEC 751), Ni100, Ni120, and Cu10 sensors. You configure the specific sensor type per channel within the hardware configuration of your engineering tool.

• Does this module require external calibration?

  No. The AI830 features factory calibration. The internal digital processing maintains high accuracy over the lifetime of the module, provided you operate it within specified environmental limits.

• What is the benefit of 3-wire over 2-wire connections?

  The 3-wire setup allows the module to measure and subtract lead-wire resistance. This ensures that the reported temperature reflects the sensor's actual environment rather than the resistance of the interconnecting cable.

• Is this a refurbished or used unit?

  Absolutely not. We guarantee this AI830 3BSE008518R1 is 100% Brand New and arrives in original ABB packaging. We do not stock surplus or repaired components.
