The Opto 22 AD6HS is a voltage input analog module designed for industrial automation, energy management, and remote monitoring applications. It provides a single channel of optically-isolated voltage-to-digital conversion, offering wide nominal input ranges and over/under range capabilities. This module is ideal for applications requiring precise voltage measurement and reliable data acquisition, particularly where ground loop problems need to be eliminated due to its 4,000 Vrms channel-to-channel isolation.
