The H7ER-N is a type of time and count meter used to measure, control and indicate elapsed time and event counts integrated into one device. This type of meter is highly accurate, convenient and versatile across its many uses. It records time and counts continuously, and its application field and working principle makes it an invaluable tool in numerous industrial and commercial settings.

Made up of two parts, the H7ER-N includes a timing and a counting module. The timing module has specific linear control elements that use an internal clock to measure and monitor elapsed time. Additionally, there are two LED indicators for total and trip time; this allows operators to easily monitor the time elapsed on the device. Similarly, the counting module allows users to accurately count up and down to record both positive and negative events. Each module has 8-bit resolution and operates on a single voltage of 24-240VAC or 12-240VDC.

The H7ER-N is typically used in two ways. Firstly, it can record the time at regular intervals, from hours to minutes or thousandths of a second, and can be programmed to log the elapsed time or count events. Secondly, it can be used to monitor and control the time it takes for a process or activity to complete by setting alarms or timers to notify users when the set time has been reached. This second use can save time, energy, and resources.

Due to its various applications, the H7ER-N is applicable in a wide variety of industries, such as factories, laboratories, hospitals, and other commercial and government entities. It can be used for precise time recording for production and quality control, as well as for counting production cycles, events, and staff attendance. It can also be used in the automotive industry for constant monitoring and testing to analyze any problems that can arise in the production process.

In terms of its working principle, the H7ER-N is equipped with internal relays that act as a switch. When the meter receives input from an external source, such as a voltage or current signal, it triggers the internal relay and the appropriate action is initiated. This could be counting or logging time or events, or displaying a total count over a specified time. The device is also equipped with other components that enable resetting and calibration.

The H7ER-N is an ideal choice for precise counting and time recording applications, and is a versatile and reliable device. Its combination of a timing and a counting module provides accurate and consistent results, which makes it a valuable addition to many environments. And since the device is adjustable, it is compatible with a diverse range of control elements and control strategies.
