171-1-120VAC
The Model 171 current monitor offers reliable performance for industrial current sensing applications. Designed for precise monitoring within the 0.1 to 1A range, this device ensures operational integrity. Its 120VAC operation and 50/60Hz frequency compatibility make it suitable for standard industrial power systems. Users can configure trip delays from 0.1 to 10 seconds and restart delays from 0.1 to 300 seconds, allowing for tailored system responses. The unit features automatic reset functionality and SPDT 10A output contacts, providing robust control. With a repeat accuracy of +/- 0.5% of the set point, the Model 171 maintains consistent performance in diverse environments. Its durable NORYL cover and 6/6 Nylon base contribute to its longevity, supporting 10 million mechanical operations. This monitor provides essential protection and control for critical equipment.
The Model 171 is an AC current monitor for detecting undercurrent
conditions. The monitor contains a proprietary microcontroller-based
circuit monitoring current passed through an internal shunt resistor and
driving an electromechanical SPDT relay. Two status lights are provided
to indicate relay status, fault condition, and timing. An adjustable
trip delay is provided to prevent nuisance tripping and an adjustable
restart delay has been provided for applications requiring a delay to
start an additional load.
