Function Description WAGO-I/O-SYSTEM 750 XTR 750-637/040-001 Inc. Encoder 24 VDC Diff 32Bit XTR Function Description </dg_ As a rule, incremental encoders supply two output signals from the encoder tracks, offset by 90°. These signals are designated A and B. The difference between the input signals is evaluated in the incremental encoder I/O module.
750-637/040-001 Inc. Encoder 24 VDC Diff 32Bit XTR Mounting Mounting Sequence Fieldbus couplers, controllers and I/O modules of the WAGO-I/O-SYSTEM 750 are snapped directly on a carrier rail in accordance with the European standard EN 60175 (DIN 35).
