Product Description:

The 779565-216 hour meter is produced by Danaher as a member of the Timers and Controllers series. It is a compact indicator intended to accumulate and display operating hours on pumps, conveyors, and other machinery so that preventive maintenance can be scheduled on a fixed runtime basis. Within an automation cabinet, the meter functions as a passive device that receives a DC supply, increments its internal counter whenever power is present, and presents clear elapsed-time data to operators. This operating method allows equipment use to be tracked without a separate sensor or external counting mechanism.

Runtime measurement is delivered over a capacity of 9999.9 hr, allowing the device to cover multi-year service intervals before rolling over. Each increment is registered in steps of 0.1 hr, so shifts as short as six minutes are captured without ambiguity. Electrical compatibility is limited to DC sources, simplifying wiring beside solid-state relays and battery backups. The bezel requires a panel cutout that is 0.95 in high by 1.45 in wide, providing a snug fit that resists movement caused by vibration. The meter can be positioned near related controls where its display remains visible during routine equipment checks.

Mechanical retention is aided by two mounting holes, each measuring 0.150 in in diameter, for straightforward front-panel fastening. The instrument has a rectangular case profile that fits standard operator-interface plates, and it weighs only 3 oz, so it imposes minimal load on thin sheet-metal doors. Panel mounting keeps the face flush with other indicators, while spade terminals support efficient harness assembly. The hour total automatically returns to zero when the maximum count is reached. The non-resettable design protects recorded operating time against accidental clearing during normal use. Its compact housing also leaves surrounding panel space available for switches, status lights, and other control devices.
