The Opto 22 AD6T is a voltage input analog module designed for industrial automation and data acquisition applications. It provides a single channel of optically-isolated voltage-to-digital conversion, offering a 0 to +5 VDC input range. A key feature is the 4000 VRMS channel-to-channel isolation, which effectively eliminates ground loop problems, enhancing system reliability. The module is designed to plug into a Standard analog I/O rack and is secured with a captive screw, ensuring a stable and secure connection. It is ideal for applications requiring precise voltage measurement and isolation from ground loops.
