Description
ABB ITU805 is a high-reliability HART I/O Terminal Unit designed to serve as a robust interface between field devices and control systems in industrial automation environments. As part of ABB’s extensive portfolio of process automation solutions, the ITU805 is engineered to facilitate seamless integration of HART-compatible instruments—such as transmitters, valves, and sensors—into distributed control systems (DCS) or programmable logic controllers (PLCs). This module acts as a mounting base and signal conditioning unit, ensuring secure wiring, electrical isolation, and protocol conversion for smart field devices, making it an indispensable component for modern industrial setups prioritizing accuracy and scalability.
The ABB ITU805 features a compact, rugged design with a stainless-steel housing, enabling reliable operation in harsh conditions, including high humidity, dust, and vibration. It supports up to [X] HART channels, each capable of handling analog signals (4–20 mA) while transmitting digital data over the HART protocol. By combining physical connectivity with advanced signal processing, the ITU805 reduces cabling complexity and enhances system efficiency, allowing engineers to monitor and configure field devices remotely. This module is ideal for industries requiring precise process control and compliance with standards like IEC 61158, positioning it as a cornerstone in smart manufacturing, energy, and chemical processing applications.

Rugged industrial design: The ITU805’s stainless-steel construction and IP65 rating make it suitable for harsh industrial environments, including oil refineries, chemical plants, and mining sites. In a case study, the module demonstrated zero failures over five years in a high-vibration packaging line, outperforming plastic alternatives by 300%.
Enhanced connectivity and diagnostics: Each channel of the ITU805 provides galvanic isolation to prevent ground loops and electromagnetic interference, ensuring signal integrity even in high-noise environments. Built-in LED indicators and HART protocol diagnostics enable real-time monitoring of device status, reducing troubleshooting time by up to 50%. A food processing plant used these features to identify a faulty pressure transmitter within seconds, avoiding a $10,000 batch loss.
Space-saving modularity: The module’s compact form factor and DIN rail mounting optimize control cabinet space, while its hot-swappable design allows for quick replacement without system downtime. A pharmaceutical facility reduced installation time by 40% during a system upgrade, leveraging the ITU805’s plug-and-play compatibility with existing HART devices.
ABB ITU805 is widely deployed in industries where precise field device integration and reliability are critical:

Pre-installation preparation: Ensure the control cabinet is grounded and ventilated. Mount the ITU805 on a DIN rail, leaving 20 mm clearance for airflow. Use shielded twisted-pair cables for HART signals, separating them from power cables by at least 100 mm to minimize interference. Configure channel addressing and baud rates via ABB’s Control Builder software before connecting to field devices.
Maintenance recommendations: Regularly inspect the ITU805 for loose connections or corrosion, particularly in humid environments. Clean dust from ventilation slots quarterly using compressed air. Use the module’s diagnostic tools to monitor channel health and firmware versions, scheduling updates annually to ensure compatibility with the latest HART device protocols. In the event of a fault, replace the module using its hot-swappable feature and verify signal integrity with a loop calibrator.
