Product Overview
The SUPCON TUA711-AI016 is a 16-channel analog input transfer terminal board designed exclusively for the SUPCON ECS-700 Distributed Control System. This terminal assembly acts as an intermediate wiring interface between AI series I/O modules and field transmitters such as pressure, flow and temperature sensors. It separates dense field cabling from the main DCS rack, simplifying cabinet layout and reducing wiring congestion within central control rooms. Process automation engineers, panel builders and maintenance technicians benefit from single-side wire entry layout and standardized terminal marking, accelerating cabinet assembly and fault troubleshooting. Compatible with non-redundant MB745-S11 and redundant MB746-S11 I/O bases, this terminal board supports hot swapping of matched analog input modules without system interruption. It complies with industrial EMC specifications to maintain stable analog signal quality in electrically noisy process environments.
Application Scenarios
- Chemical Plant Continuous Production Control: Connects hundreds of 4–20mA field transmitters inside main control cabinets. Modular terminal arrangement streamlines cable routing for distillation columns, reactors and heat exchange units.
- Water & Wastewater Treatment DCS Systems: Receives measurement signals from level, flow and water quality transmitters. Organized terminal layout speeds up routine inspection and sensor calibration work.
- Power Plant Auxiliary Equipment Monitoring: Deployed in boiler and flue gas treatment control cabinets. Supports redundant I/O configurations to enhance reliability for safety-critical measurement loops.
- ECS-700 DCS Expansion & Retrofit Projects: Used as standard spare hardware for system upgrades. Matches existing wiring schemes to minimise rewiring and commissioning labour during maintenance overhauls.
