Why Choose the WAGO 750-631/000-004 Incremental Encoder Interface?
The WAGO 750-631/000-004 is an incremental encoder interface module designed for the WAGO I/O System 750 and 753. It enables direct integration of incremental encoders with RS-422 differential outputs into PLC-based automation systems, allowing precise position and speed measurement within distributed control architectures.
The module reads the encoder signals A/A̅, B/B̅ and C/C̅ and processes them through a 16-bit quadrature counter. This allows accurate tracking of motion, rotation and position changes. The measured count values are transmitted directly via the fieldbus to the PLC, industrial PC or motion controller for real-time monitoring and control. :contentReference
Designed for high-speed motion applications, the module supports encoder input frequencies of up to 1 MHz and provides a 16-bit latch for the zero impulse. This ensures precise capture of reference positions in automation systems such as CNC machinery, robotics and packaging equipment. :contentReference
