Product Description:
The HP57A622 is a robust timer from Danaher that offers water resistant construction, a wide 0–150-minute adjustable range and a large, clearly marked dial for precise control, ideal for an automation field that requires reliable, visible and flexible time management.
The HP57A622 timer is capable of returning to its original state in just 0.5 seconds after it reaches its maximum setting and completes its cycle and ensures minimal downtime between cycles. This module can manage electrical loads up to 10 amps operating at 120 volts alternating current without inductive or capacitive components such as heaters or incandescent lights and it is built to run on power systems delivering 60 hertz, which is the standard electric grid frequency in regions like North America. In this timer, it is possible to set the desired time manually by rotating a control knob which enables precise configuration based on task requirements or system timing and it remains fully operational within 0 to 140 degrees Fahrenheit. Its physical mass is just under 3 pounds, which provides a stable form factor without being excessively heavy and contributes to secure mounting and resistance to minor external forces.
This HP57A622 timer takes roughly 28 thousandths of a second to activate once power is supplied and it takes about 17 milliseconds to release when power is removed which helps reduce lag and ensure near instantaneous switching for time sensitive operations. It matches the standard outlet voltage in many industrial settings as it is designed to run on a 120 volts supply and it is highly stable under 2.5G vibrations from 10 to 900 Hz in all directions which means it remains unaffected by mechanical tremors or vibrations at intensities up to 2.5 times gravity.
Frequently Asked Questions about HP57A622:
Q: Can the HP57A622 timer be used in environments with frequent vibration?
A: Yes, it is engineered to remain stable under vibrations up to 2.5G across all axes. This makes it suitable for machinery, transport systems, or vibrating enclosures.
Q: How does the quick reset capability affect automation workflows?
A: Its 0.5-second reset time minimizes cycle delays, which is critical for high-speed or repeat-cycle automation systems. This enables tighter control over process timing and throughput.
Q: Is manual time adjustment precise enough for industrial tasks?
A: The large, marked dial allows fine-tuning by hand, offering clear visual feedback. This is ideal for applications where frequent or incremental adjustments are required.
Q: Does the HP57A622 timer support inductive or motor loads?
A: No, it is rated for resistive loads only, such as heating elements or lamps. Using it with inductive loads may cause premature failure or inaccurate timing.
Q: What kind of timing flexibility does this device offer?
A: It allows timing from a few seconds up to 150 minutes, adjustable via the dial. This range supports short-cycle testing or longer hold delays in process control.
