Quadrature encoder

Advantech has introduced the ADAM-5081, a high-speed quadrature encoder and counter module for use with the ADAM-5550 series programmable automation controllers (PACs).

The 5081 has a high isolation of 2500 VDC, a high-speed frequency mode (5 Hz <0x007E> 1 MHz) and a counter code at 1 MHz.

There’s also a digital filter to eliminate noise and interference (1 <0x007E> 65,000 µs), which ensures accurate data collection and transmission.

The encoder features four counter modes (up/down, bidirectional, up and A/B phase modes), which counts precise data units in minute detail.

The frequency mode supports up to eight channels and can control a wider range of electromagnetic wave status under certain conditions.

It 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. Once the preset value is reached, the system requires a digital output signal to trigger the camera.

With built-in DO channels, the respond speed is maximised.
