Basic Information

Original American-made 3500 system-specific TMR triple-redundant communication module, full-height size, metal reinforced housing, supports hot-swappable operation while powered on; complies with API 670 standard, specifically designed for high-reliability critical equipment, must be installed in slot 1 of the 3500 rack (adjacent to the power supply), one per frame is required.

Function and Positioning

As the core gateway of the 3500 monitoring frame and the upper System 1 software, it is responsible for high-speed collection and transmission of steady-state + transient data (waveforms); integrates 3500/20 RIM functions and communication processing capabilities, supports TMR triple-redundant voting, ensures data integrity and system fault tolerance, supports rotating machinery fault diagnosis, trend analysis, and protection interlock.

Core Performance Parameters

Interfaces: TDI standard interface, compatible with RS232 / Ethernet

Data: Supports parallel transmission of transient waveforms (vibration / displacement / rotational speed) + steady-state parameters

Redundancy: TMR triple-redundant configuration, a single card failure does not affect system operation Power supply: 24V DC

Power consumption: ≤ 20W

Operating temperature: -20℃ to +60℃

Slot: Fixed Slot 1 (Power Side)

Compatible accessories

3500/05 frame, 3500/15 redundant power supply, RS232 / Ethernet communication cables, System 1 software license, rack mounting backplane. Applicable scenarios

The TMR architecture TSI system for key rotating machinery such as thermal power / nuclear power turbines, gas turbines, large compressors, and generators is the core card for data communication and safety protection of the entire unit.
