I. Basic Information
Model: 9662-6 (Full common model: 9662-610)
Original factory material code: 3000520-390
Brand: Triconex (a subsidiary of Schneider, Invensys)
System: Tricon 3000 Series TMR Tri-Redundant SIS Safety Instrumentation System
Product Type: Digital Output FTA Field Terminal Assembly
Mandatory main control I/O card: Compatible with Tricon 3510, 3511 series digital output modules (DO card), connected to the DO card in the rack and the on-site load circuit through a dedicated flat cable
Core Functions
As a wiring transfer terminal board for connecting the system DO card with on-site solenoid valves, relays, indicator lights, and circuit breaker trip circuits, it centrally distributes multiple switch quantity output circuits
Built-in circuit fuses and status indicator lights. A single circuit short circuit only melts the fuse of this circuit, will not cause a complete card failure, facilitating fault location
Strong and weak electrical isolation design, suppressing on-site surges and reverse electromotive force interference, protecting the TMR control card on the rack side from being broken by high voltage
Supports SIL3 safety level application, with loop break, load fault diagnosis feedback, and can monitor the status of each output circuit in the upper TriStation software
Key Electrical Parameters
Working Voltage: DC24V / AC120V universal compatibility
Maximum single circuit load current: 5A, each circuit is configured with an independent delay fuse
Insulation withstand voltage: Strong and weak electrical circuits isolated 500VDC
Operating environment: -20℃～+70℃, no condensation, installed in the cabinet on DIN rails
Protection level: IP20
Safety Certification: SIL3, CE explosion-proof area compliance certification
Hardware Interface Configuration
Back end: High-density dedicated wiring interface, connecting the DO control card in the rack
Front end: Green European-style spring terminals, multiple DO output wiring positions, each circuit with a fault indicator + fuse seat
Integrated circuit fault detection circuit, can upload open circuit, short circuit, overload alarm signals to the system
Typical Application Scenarios
SIS emergency shutdown system (ESD) in petroleum, chemical, and coal chemical industries
FSSS furnace safety monitoring, ETS trip protection system for power plant unit boilers and steam turbines
Safety interlock control circuits for long-distance oil pipelines, storage tank areas, emergency cut-off valve control circuits
Safety interlock protection control cabinets for key equipment in metallurgy and pharmaceutical industries
