Luxtron m924 Utility
OEM Board for Fiber Optic Transformer Winding Hot Spot and Temperature Monitoring
Advanced Energy's Luxtron m924 utility module is a cost-effective OEM board that provides temperature monitoring with RS485 Modbus and RS232 ASCII digital communication.
- Four channels, expandable up to 64
- Direct, accurate, and real-time transformer winding hot spot and temperature monitoring
- Backward compatible with Luxtron DipTip and quality probes for utility applications
- Technical Specs
- Service & Support
The Luxtron® m924 utility module is one board that contains four fiber optic temperature sensing channels, RS232 ASCII and RS485 Modbus digital outputs, and 5 to 24 VDC power input connection. The m924 board conditions the measurement signal from Fluoroptic® probes and reports to the OEM control system. The custom non-metallic probe sensors are safe in harsh environments and connect to the m924 board via robust fiber optics.
The m924 is a guaranteed backward compatible module when using Luxtron Fiber Optic DipTip and quality probes, extension cables, and tank wall plates.
