Omron H7HP-C8D Counter

The Omron H7HP-C8D Counter supports 12 to 24 VDC operation, offering efficient totalizing performance through an 8-digit red backlit LCD for enhanced visibility. It handles 30 Hz and 5 kHz counting speeds with UP/DOWN input, making it suitable for both light and high-speed applications. External/manual reset functions improve usability, while EEPROM memory retention and IP66 oil-resistant protection deliver long-term reliability. Its robust design also ensures strong noise, vibration, and shock resistance for industrial use. Manufactured by Omron and featured under Omron Counter products, it belongs to the Omron H7HP Series.
