LM-HH2AS-H11

The LM-HH2AS-H11 from Automation Direct is an electrical panel meter that is used in manual start / stop timing applications. It has a backlit LCD display that can be configured to either read clockwise or counterclockwise for measuring elapsed time from manual time control or time-based automation. The LM-HH2AS-H11 has two timing ranges that can be selected from 0-9999.99 hours or 0-999.999 hours depending on the application need. It also has a reset button on the back of the unit that can be used to reset the timer to 00:00.This panel meter is designed to be used in industrial and commercial applications where accurate time measurement is required for operations efficiency or safety monitoring. Examples of such applications include machine tools and inspection equipment, conveyors, production line equipment, pressure equipment testing, pump, motor, and boiler maintenance, mechanical equipment testing, and maintenance and repair scheduling.When installed, the LM-HH2AS-H11 operates from a source of direct current voltage. It can be wired in normally open or normally closed setup. When in the normally closed mode, the timer will not start until the electrical current is cut. After it is initiated, the timer will count down until the power is cycled or until the reset button is depressed.In terms of accuracy, the LM-HH2AS-H11 provides a resolution of 0.01 hours and has a count accuracy of ±0.01%. This accuracy is achieved by using a high-precision crystal oscillator as the time base, which helps to ensure that the timer will always display the correct elapsed time down to the second.In terms of installation and maintenance, the LM-HH2AS-H11 is very easy to install and use. The unit comes with a fixed DIN-rail mount that allows for quick and easy installation. The timer also has a modular construction that makes it easy to disassemble and reassemble for servicing or replacement.In summary, the LM-HH2AS-H11 from Automation Direct is a very reliable and easy to use panel meter that is designed for manual start / stop timing applications. It has two timing ranges, a backlit LCD display, and a reset button for convenient manipulation. Additionally, the LM-HH2AS-H11 is accurate and easy to install and maintain, making it an ideal choice for industrial and commercial applications.
