TRICONEX 3000470-510 + 9760-210 Complete Set of Terminal I/O Base Plate

TRICONEX 3000470-510 + 9760-210 Complete Set of Terminal I/O Base Plate

I. Overview of Basic Products
Brand: TRICONEX (a subsidiary of Schneider)
Parent System: Tricon Triple Redundancy TMR Safety Instrumentation System (SIS/ESD Emergency Shutdown System)
The two are used together as a complete set: one analog terminal board + one digital input/output terminal base board, assembled in pairs below the I/O module, serving as the connection base for on-site cables and the main control I/O card for wiring.
3000470-510: Analog Signal Terminal Board
9760-210: Digital Input/Output Switch Input Terminal Base Board

Detailed Parameters and Functions by Model
1. TRICONEX 3000470-510 Analog Terminal Board
Main Function
Collect on-site pressure, temperature, and flow transmitters with 0-5V / 0-10V standard analog voltage signals, perform signal conditioning, electrical isolation, circuit break detection, and convert them to upper-level AI analog input cards; suitable for SIL3 safety level conditions
Supported Signals: 0-5VDC, 0-10VDC single-ended analog voltage
Built-in channel fault diagnosis: Real-time reporting of break, short circuit, and voltage over-limit to the system
Electrical Isolation: Optical isolation between channels, resisting power grid surges and industrial electromagnetic interference
Structure: Screw terminal block, convenient for on-site cable crimping and wiring
Compatible with upper-level: Tricon full series of analog input redundant card components
Protection: PCB three-proof coating, suitable for humid and corrosive environments in chemical plants and power plants
2. TRICONEX 9760-210 Digital Input Terminal Plate
Main Function
Connect switch quantity DI signals such as circuit breaker position, limit switch, fault relay contacts, local start/stop buttons, etc., complete digital signal filtering and anti-shake processing, and transmit them to the triple redundant digital input card; participate in unit interlock, emergency shutdown logic judgment
Compatible Signals: 24VDC passive dry contact switch signals
TMR three-way synchronous acquisition, triple-two voting, single-point line fault will not cause signal misjudgment
Panel LED indicator lights: Each channel’s on/off status is intuitively displayed, facilitating inspection
Support for hot-swappable modules: The terminal plate can be replaced independently without stopping the cabinet, without interrupting the safety protection system operation

Common Hardware Characteristics of the Entire System
Safety Level: Certified by IEC61508 SIL3, standard safety components for ESD systems in petrochemical and thermal power gas turbine plants
Power Supply: Unified 24VDC power supply from the Tricon system backplane, no need for external power supply
Operating Environment
Operating Temperature: 0℃ ~ +65℃ (constant temperature in the control room)
Storage: -40℃ ~ +85℃
Corrosion grade G3, fourth-level EMC anti-interference, suitable for harsh conditions in refineries and offshore platforms
Installation Method: Rack backplate snap-fit installation, card stack structure
Overall Advantages
Triple redundant architecture for fault tolerance, loop self-checking, online maintainability, is the core wiring component for scenarios where process equipment cannot be shut down
