The ENC7480 is a PCI plug-and-play board that provides inputs and decoding for up to four incremental quadrature encoders or linear scales. In addition, the ENC7480-IO has 32 general inputs and 32 general outputs.

Incremental quadrature encoders and linear scales are used to provide feedback signals from motors and actuators, that is, to count rotations & linear movements and convert the physical movement into a series of electrical signals. These signals are sent to the computer which then decides whether or not to trigger signals that control the motor’s movement and what those control signals should be. The ENC7480 is the link between up to four incremental quadrature encoders and the computer. They can be used for a wide range of measurement and motion control applications, such as CNC machines, robotics and co-ordinate measuring machines.

The ENC7480 provides 4 encoder inputs, each with a 28-bit position counter whose maximum count rate can be up to 6.5MHz. Two trigger/capture signals optional (TR1, TR2), and counters can be read on the fly or be captured by triggers to be read later.

Software support for modern rapid application development tools, such as Visual Basic, Visual C and LabVIEW.
