Product Overview
The SUPCON TUA711-GS00 is a universal remote transfer terminal board developed for the SUPCON ECS-700 Distributed Control System. This terminal unit creates physical separation between I/O module racks and field wiring cabinets, enabling flexible layout design for large-scale control rooms. It pairs with MB745-S11 non-redundant bases or MB746-S11 redundant bases to connect single or dual hot-backup I/O modules, transmitting analog and digital signals between field instruments and DCS hardware. It resolves wiring congestion issues within main control cabinets and simplifies cable routing for long-distance field connections. DCS system engineers, panel builders and plant maintenance teams benefit from single-side wire entry layout and standardized terminal marking, accelerating cabinet assembly and fault troubleshooting. The terminal board supports hot swapping of matched I/O modules and complies with industrial EMC standards for stable signal transfer in electrically noisy process environments.
Application Scenarios
- Chemical Plant Centralized DCS Cabinet Layout: Separates main control racks and field terminal cabinets to reduce wiring clutter. Remote terminal arrangement facilitates orderly cable management for hundreds of transmitters, control valves and switch sensors.
- Power Plant Auxiliary Control Systems: Deployed in boiler and flue gas treatment DCS cabinets. Supports redundant I/O module configuration to enhance system reliability for safety-related process loops.
- Oil & Gas Processing Unit Automation: Organizes field instrument wiring for distillation and separation processes. Clear terminal labeling shortens diagnostic work during routine inspection and maintenance.
- ECS-700 System Expansion & Retrofit Projects: Used as spare hardware for upgrading existing DCS installations. Compatible with mainstream ECS-700 I/O modules to avoid modification of control logic and field cabling.
