Key Features
- Supports configurable Modbus register mapping, flexible selection of monitoring parameters uploaded to upper control systems
- Simultaneous operation of Ethernet and serial channels; data can be sent to two independent control systems at the same time
- Built-in communication self-diagnosis, detects cable disconnection, node offline and communication overtime
- Electrical isolation on communication ports, enhances anti-interference capability in turbine vibration cabinet environments
- Compatible with all standard 3500 series monitoring modules (vibration, speed, temperature, relay modules)
- Strict full part number verification required; different hardware revisions cannot be directly interchanged without configuration download
- Essential spare communication hardware for power plant steam/gas turbine monitoring & protection racks
