NABTESCO ML-800-V TELEGRAPH LOGGER
NABTESCO ML-800-V is a marine telegraph logger designed to work with Nabtesco M-800 series bridge maneuvering and engine telegraph systems for commercial vessels. This telegraph logger continuously records bridge telegraph orders, engine room reply signals, main engine RPM, date and time stamp on recording paper. The telegraph logger captures every change of maneuver command including ahead, astern, stop and dead slow, fulfilling SOLAS mandatory voyage recording requirements. The telegraph logger integrates local display, test function and paper feed control for on-site inspection and log verification. The telegraph logger serves as essential navigation spare unit for wheelhouse console maintenance and marine telegraph system retrofit.

This ML-800-V unit adopts panel mount design with 24VDC 3.0A marine power supply. ML-800-V connects to the telegraph system via dedicated signal interface to receive order and feedback data. ML-800-V supports built-in self-test function and status LED indicators for quick fault diagnosis. ML-800-V is type approved by major marine classification societies, widely installed on bulk carriers, tankers and container ships equipped with Nabtesco remote control systems.

As mandatory voyage recording hardware, this NABTESCO logger maintains reliable paper print recording under wheelhouse vibration, temperature variation and salt-laden air environment. NABTESCO M-800 series marine spare parts include telegraph transmitters, receivers, ML-800-V loggers and recording paper for bridge maneuvering system overhaul. NABTESCO telegraph loggers are trusted replacement units for legacy marine engine order recording systems.
