Reliable Cumulative Time Tracking

Omrons H7ER-NV-B counter provides highly accurate cumulative time measurement for equipment and panels. Its precision is ensured by 0.1% RDG 1 digit accuracy and an eight-digit display. The non-resettable function makes it well-suited for tracking total operating hours for maintenance planning and regulatory compliance.

Designed for Durability and Ease of Installation

The front panel is IP66-rated against dust and water, ensuring reliable operation in demanding environments. With a flush-mount design and screw terminals, installation is straightforward in control panels. Its compact build, only 50g and measuring with a standard panel cutout, facilitates integration into various equipment.

Low Power, Long Life Solution

The built-in lithium battery supports up to 7 years of continuous operation at 25C, making it ideal for applications where power reliability and minimal maintenance are essential. This design ensures lasting performance even in environments with variable power supply.

FAQs of Omron H7ER-NV-B Counter:

Q: How do I install the Omron H7ER-NV-B counter in my panel?

A: To install the Omron H7ER-NV-B, prepare a 45 x 22 mm cutout in the control panel for flush mounting. Secure the unit using appropriate panel-mounting hardware and connect input signals and power via the screw terminals for a secure electrical connection.

Q: What kind of input signals are compatible with this counter?

A: The H7ER-NV-B supports input from no-voltage contact or open collector switches. The minimum input signal width required is 20 ms, and it can handle a maximum counting frequency of 30Hz.

Q: When should I consider replacing the device due to battery life?

A: The counter is powered by a non-replaceable lithium battery designed to last at least 7 years under continuous operation at 25C. When the battery nears its end of life, the entire unit should be replaced, as the battery is not user-serviceable.

Q: Where is the Omron H7ER-NV-B most beneficially applied?

A: This counter is ideal for tracking total operating hours in industrial equipment and control panels, primarily where resettable counters are not desired, such as monitoring machine maintenance cycles, regulatory inspection intervals, or cumulative usage logging.

Q: What are the benefits of the IP66 front panel rating?

A: The IP66 rating protects the front panel from dust and strong jets of water, ensuring reliable performance even in harsh or washdown environments, making it suitable for factories and outdoor panel installations.

Q: How does the counters accuracy impact my operation logging?

A: With an accuracy specification of 0.1% RDG 1 digit, the Omron H7ER-NV-B reliably records time or counts, providing dependable tracking for critical maintenance, usage-based billing, or regulatory reporting.

Q: What process does the hour meter/counter use to display measurements?

A: Measurements are displayed on an 8-digit LCD with a backlight (for the -NV-B model), presenting hours or counts depending on the application, with a resolution as fine as 0.1 hour and up to a full range of 99,999.99 hours or 99,999,999 counts.
