Description

Quadrature Incremental Decoder Interface for VMEbus – VME323

The VME323 is an Intelligent Quadrature Incremental Decoder VMEbus Board which can be configured for interfacing quadrature incremental encoders with or without an index channel. In index mode up to sixteen encoders with two quadrature channels and an index channel can be connected, and in non-index mode up to twentyfour encoders with two quadrature channels can be connected. The VME323 operates on two encoder input channels and decodes a pair of out-of phase signals in order to increment or decrement a counter.
This VMEbus board has a 6U form and is also available as 3U VMEbus board.
