Allen-Bradley 1771-IAD Key Features
Enhanced Anti-Interference Design: The Allen-Bradley 1771-IAD utilizes an isolation transformer and digital filtering technology to maintain signal stability even in high-electromagnetic interference environments, such as arc furnace plants.
Channel-Level Fault Diagnostics: Each input channel features an independent status LED, allowing maintenance personnel to quickly locate Allen-Bradley 1771-IAD module faults such as disconnection or over-range.
Hot-Swap Redundancy Support: Combined with the 1771-A1B/A2B chassis, the Allen-Bradley 1771-IAD can be replaced online without interrupting production, a highly valued feature in refinery DCS systems.
Allen-Bradley 1771-IAD Application examples
North American oil pipeline pressure monitoring: Chevron has deployed over 800 Allen-Bradley 1771-IAD sensors on its Alaska pipeline, leveraging their -40°C low-temperature tolerance (with the addition of a thermostat) for 25 years of continuous operation.
German automotive stamping line: Volkswagen's Wolfsburg plant uses Allen-Bradley 1771-IAD sensors to collect hydraulic oil level signals on its 2,000-ton presses, meeting servo control requirements with an accuracy of ±0.5%.
