Carte d'assemblage sur rail DIN GE IS230TAISH2C Mark VIe TMR

Description

The TMR DIN rail assembly board functions as a high-reliability hardware interface designed for the General Electric Mark VIe control platform. The IS230TAISH2C facilitates critical signal routing and field wiring integration, enabling structured connection pathways for sensors and actuators in mission-critical applications. By supporting Triple Modular Redundancy (TMR) architectures, this board provides cross-channel signal availability and hardware fault tolerance across dual or triple controller infrastructures linked via the high-speed IONet communication protocol. This continuous synchronization and majority voting capability ensure absolute data integrity for continuous process operations in demanding heavy industries like thermal power stations, petrochemical plants, and oil refining infrastructure.

Features

• Equipped with an onboard heavy-duty terminal block providing up to forty-eight (48) individual field wiring terminals.
• Supports scalable redundant system architectures, interfacing seamlessly with simplex, dual, or fanned TMR controller layouts.
• Native alignment with high-speed IONet communication channels to handle precise controller state synchronization and voting tracking.
• Designed for standard 35 mm DIN-rail mounting configurations to optimize high-density cabinet layouts and installation workflows.
• Certified under strict industrial safety listings for dependable deployment in hazardous and non-hazardous operating zones.

Applications

• Steam and Gas Turbine Protection Systems
• Triple Modular Redundant (TMR) Control Architectures
• Emergency Interlocking and Safety Shutdown Panels
• Power Generation Plant Automation Infrastructure
• Hazardous Area Field Instrument Distribution Links

Installation Guidelines

• DIN Rail Mounting: Mount the assembly board horizontally or vertically on a standard 35 mm symmetric DIN rail. Ensure the locking tabs are completely engaged with the rail structure to resist cabinet vibrations.
• Field Conductor Wiring: Strip field device and sensor signaling cables to the standard specified insulation length. Secure individual leads into the 48-point terminal block using calibrated screwdrivers to maintain accurate electrical contact tension.
• Shielding and Data Integrity: Route incoming low-voltage sensor lines through dedicated grounded wire trays. Connect cable drain wires directly to the designated cabinet enclosure earth bar to suppress industrial electromagnetic interference (EMI).

Compliance and Certifications

• UL E207685 Certification (Non-Hazardous Environments)
• Class I, Division 2, Groups A, B, C, D
• Class I, Zone 2, Group IIC
