Description
The Omron H7ET-NV1-B is a self-powered miniature time counter designed for accurately measuring and displaying the operational time of industrial machinery and equipment. This compact unit features a clear 7-digit LCD display and operates without an external power supply, drawing its minimal power from the input signal. It excels in counting elapsed time in two selectable ranges, up to 9999 hours and 59.9 minutes or 999 hours, 59 minutes, and 59 seconds. With a wide operating voltage range of 4.5 to 30V DC, IP66 front protection rating, and a compact 22.2mm x 45mm cutout, it is an ideal solution for panel mounting in control cabinets where space is limited and long-term, maintenance-free operation is required.
