Product Description:

The global leading manufacturer Danaher is the maker of the 779555-216 module which represents the famous Timers and Controllers range. As a rugged, panel‑mounted hour meter and totalizer, this device features a non‑resettable mechanism which prevents accidental counter resets during operation. Input voltage ranges from 10 to 32 VDC which supports integration into diverse DC systems. A panel cutout of 2.00 inch diameter allows consistent and standardized installation across control boards.

This industrial unit is tamper‑proof that helps basically get recorded hours secured against unauthorized adjustments. Moreover, the controller mainly displays capacity reaches up to 99999.9 hours in order to monitor long operational cycles without display overflow. The inclusion of spade terminals serves as connections which simplify wiring and maintenance. Resolution of 0.1 hour offers precise time tracking and enables fine-grained usage analysis. Working temperature ranges from -40° to +185°F (–40° to +85°C) and it ensures functionality in extreme industrial conditions. Sealing safeguards against dirt and moisture to maintain internal component reliability. Also, a round case form delivers a compact physical presence for a fit tight panel spaces.

Additional data sourced from the product manual includes an accuracy rating of 0.02 percent which guarantees precise time measurement across the full scale. Automatic recycle at zero upon hitting maximum readout resets without manual intervention, thus supports continuous operation. Approximate weight of 0.2 lbs. ensures minimal load on installation panels which eases structural demands. Shock resistance classification meets 50 g impulse performance to withstand heavy vibration environments. Timer’s mounting style remains a panel-mount round case and that offers uniformity across mounting locations.
