16-bit RS-422 incremental encoder interface with 5 V system supply, 1000 kHz limit frequency, IP20, DIN-rail mount.
DIN-rail incremental encoder interface module for WAGO 750 I/O systems. The device accepts RS-422 incremental encoder signals, provides 16-bit counter and 16-bit latch functions, and transmits counts fast and interference-free over the fieldbus. It is powered via 5 V system supply through data contacts and supports a 1000 kHz limit frequency. The module is rated IP20 and is designed for 750-series PLC/I/O applications requiring precise motion feedback capture.

Captures high-speed quadrature encoder pulses from an incremental encoder and forwards count data to a PLC for axis position tracking.
Prevents missed pulses in motion systems that need accurate position feedback at up to 1000 kHz.
Provides reliable count and zero-reference capture for conveyor indexing or registration tasks using the latch input for home/marker pulse detection.
Maintains repeatable indexing when line speed changes and a fast zero impulse must be preserved.
Interfaces with encoder signals in industrial machines where compact DIN-rail mounting and 500 V isolation simplify cabinet integration.
Allows isolated encoder interfacing in electrically noisy cabinets while keeping the I/O module footprint compact.
