Product Description:

The HP55A601 Timer of Danaher is a high quality unit which is dependable and robust in time delay operations and the type of the function in this HP5 CYCL-FLEX SERIES is a Reset Timer that is very reliable in restart in each successive cycle. It operates at the frequency of 60 Hz capable of supporting standard power systems without the need for frequency conversion and its timing mode is Off Delay/Standard that provides control after the removal of input power supply.

The HP55A601 timer features 16 standard time ranges that offer flexibility across a wide span from 5 seconds to 60 hours which makes it adaptable to diverse timing requirements in various automated processes. It is rated at a voltage of 120 volts AC that can be used with typical electric systems and in addition to this, it possesses knob adjustable time ranges that enable the user to alter timing adjustments without using tools that save time setting it up. It has a reverse clutch mechanism and it gives mechanical integrity where it is necessary to reset operations and it will assure reliable disengagement, re-engagement operations which are very important where they are repetitive in control sequences. Its weight is 1.13 kgs which helps in easy mounting on control panels or assemblies and it is designed to be integrated into a system where timing repeatability and an accuracy is required that includes applications in industrial automation.

This HP55A601 timer design supports consistent output timing that is essential for process stability and synchronization and it delivers controlled delay functionality that supports time sensitive sequences. It facilitates functions that require controlled delay and reset periods and it is suited to system expectations that focus on timing integrity and low-drift.
