Product Description:
The HP57A6 reset timer uses a motor-driven dial to control time-based switching with manual reset and no digital components. Danaher has engineered this model to support consistent functioning across a wide range of industrial automation timing tasks.
The HP57A6 reset timer is a panel-mounted unit from the HP5 CYCL-FLEX series. It offers knob-adjustable time settings within a 0 to 150-minute range which helps in allowing manual control of timed operations through a front-facing rotary dial. It operates on a 120 VAC power supply at a frequency of 60 Hz which ensures its execution for the desired working. It just weighs approximately 0.42 kilograms and is easily used without requiring any extra space and maintenance in industries. The timer is commonly used in control systems requiring precise on-delay timing where a manual reset is also necessary. The core working principle of this unit is based on a synchronous motor and cam mechanism which advances the timer according to the position of the dial. Once the preset time elapses the internal contacts change state to signal the end of the timing cycle. Resetting the unit can be achieved manually by returning the system to its initial state and readying it for the next cycle.
The HP57A6 timer face includes an easy-to-read scale marked in 10-minute increments with intermediate markings for finer adjustment. The control knob provides a solid grip and smooth rotation which is highly suitable for industrial environments. A front cover latch holds the mechanism securely while the enclosed manual and included mounting hardware support straightforward installation. It contains a black color rating material that aids in providing insulation and protection against various harms.
Frequently Asked Questions about HP57A6:
Q: What is the timing range supported by the HP57A6 timer?
