800H-UR55 ALLEN-BRADLEY Potentiometer Vac

Review ALLEN-BRADLEY Potentiometer Watt Max 300 Vac Series

The Allen-Bradley Model 800H-UR55 Potentiometer is a versatile and reliable electrical component designed for use in various industrial automation applications. This potentiometer, which is suited for voltage measurements up to 300 Volts Alternating Current (VAC), offers a number of features that make it an excellent choice for various control systems.

The 800H-UR55 Potentiometer boasts a rugged construction, specifically designed to withstand harsh environments often encountered in industrial settings. The potentiometer's housing is made of either phenolic resin or polycarbonate, depending on the specific version, and comes with sealing gaskets to ensure the protection of internal components against dust, water, and other contaminants. This ensures reliable operation in temperature ranges of -20 to 70 Celsius.

The 800H-UR55 Potentiometer features a 5-wire, 10-turn design, which offers increased accuracy and improved temperature compensation as compared to more traditional 3-wire designs. The linear taper of the potentiometer ensures consistent resistance changes within the total travel range, enabling precise voltage measurements.

The precise and linear output of the Allen-Bradley 800H-UR55 Potentiometer makes it an ideal component for various control systems, such as voltage regulation, lamp dimming, and process control. Its low electrical resistance (

Additionally, the 800H-UR55 Potentiometer comes with easy-to-read calibration marks on its rotary shaft, offering convenient and accurate field calibration. Over-travel protection ensures that the potentiometer meets safety standards, preventing accidental contact with the wiper when the shaft is rotated beyond the usable range.

The Allen-Bradley 800H-UR55 Potentiometer's high-quality construction, superior performance specifications, and easy field calibration make it a reliable and indispensable component for various industrial automation applications, particularly those requiring accurate voltage measurements up to 300 VAC.

The Allen-Bradley 800H-UR55 potentiometer is a 300VAC variable resistor commonly used in industrial automation applications. Like any other product, it has its advantages and disadvantages. Below are some pros and cons:

1. Industrial Grade: Allen-Bradley is a trusted name in the automation industry, known for producing high-quality components. The 800H-UR55 potentiometer is designed to operate in harsh environments, ensuring reliability and durability.

2. Wide Range: The potentiometer offers a wide resistance range from 1.25 ohms up to 400,000 ohms, allowing flexibility in various automation applications.

3. Integral Heater: This feature enables the potentiometer to maintain a stable and accurate resistance value in cold temperatures by heating the wiper element.

4. Multiple Terminal Configurations: The Allen-Bradley 800H-UR55 potentiometer offers different terminal configurations such as compatible terminal blocks and quick-connect terminals, enhancing ease of use and installation.

1. Cost: Being an industrial-grade component from a reputable manufacturer, this potentiometer comes with a higher price tag compared to generic alternatives.

2. Requires Hand Tuning: Unlike digital potentiometers or other devices with programmable resistance values, the Allen-Bradley 800H-UR55 requires manual adjustments, requiring more time for calibration and set-up.

3. Limited Current Handling Capability: With a maximum continuous current rating of 100mA, the Allen-Bradley 800H-UR55 potentiometer may not be suitable for heavy current applications, leading to potential damage.

The Allen-Bradley 800H-UR55 potentiometer is an ideal choice for those seeking a high-quality, rugged solution for their industrial automation requirements, where precise manual adjustments and a wide resistance range are essential. However, it may not be the most cost-effective or suitable option for low-current or high-current applications. Ultimately, the decision to purchase the Allen-Bradley 800H-UR55 comes down to your specific application requirements and budget. For high-volume, cost-sensitive applications, one may consider alternative, lower-cost options from other reputable manufacturers, or potentially explore digitally controlled resistance components.
