Incremental quadrature encoders and linear scales are used to provide feedback signals from motors and actuators, that is, to count rotations or linear movements and convert the physical movement into a series of electrical signals. With the ENC7480/ENC7480-IO, the user can get the IO, encoder or linear scale signals easily on a PC with Visual Basic, Visual C, LabVIEW, etc.Leadshine ENC7480 / ENC7480-IO PCI encoder counter cards are plug-and-play boards that provide digital inputs & outputs and decoding for up to four incremental quadrature encoders or linear scales. The ENC7480-IO has 32 general inputs and 32 general outputs.
