The ADAM-5081 high-speed quadrature encoder and counter module from the Industrial Automation Group of Advantech (Cincinnati, OH) provides isolation of 2,500VDC, a high-speed frequency mode (5 Hz to 1 MHz), and a counter code at 1 MHz. An advanced digital filter eliminates noise and interference.

The ADAM-5081 features four counter modes (up/down, bi-directional, up and A/B phase modes), which counts precise data units in minute detail. The frequency mode of the ADAM-5081 supports up to eight channels and can control a wider range of electromagnetic wave status under certain conditions.

The encoder supports four digital output channels, which can be triggered by a preset counter value, and can watch the position encoder of the machine while doing the position comparing.
