Product Description:
Danaher’s 779536-201 is a timer and controller device with a non-resettable hour meter. This ensures runtime data remain intact without the risk of accidental erasure. Its display supports up to 99 999.9 hours, making it ideal for tracking prolonged equipment operation in continuous-use systems. With screw-terminal connectors, this commercial unit secures wiring effectively, resisting vibration-related loosening in rugged environments. An automatic zero-point recycle restarts counting after reaching full capacity to enable seamless operation through repeated maintenance cycles.
The meter delivers 0.02 percent display accuracy. It allows reliable time tracking over long durations while minimizing cumulative timing errors in high-precision workflows. A shock-resistant, lightweight enclosure cushions internal mechanisms which shield them from mechanical impact in active field conditions. As an electromechanical hour meter, it combines durable physical components with simple operation, eliminating issues like electronic drift. Further, the sealed design resists dirt and moisture, maintaining performance integrity in demanding industrial environments. Measuring 0.95 in × 1.45 in, the cutout fits standard rectangular panels for quick integration into existing setups. The rectangular panel-mount format holds the meter firmly in place, even under persistent vibration.
Rated for 120 VAC input, the unit connects directly to standard facility voltage, thus avoiding the need for external converters. With a 0.1-hour resolution, it provides detailed time increments to support precise scheduling for maintenance and inspections. Permissible temperature range between -40°F to +185°F (–40 °C to +85 °C) allows dependable use across extreme climates without thermal-related failures. Its six-digit wheel and dial display offers a clear and user-friendly interface. At just 0.03A current draw on 120 VAC, it places minimal demand on power systems, supporting compact and power-efficient panel configurations.
