Motrona GV471 Pulse Distributor for Incremental Encoder 4 Outputs

This compact and versatile pulse splitter / signal distributor has 1 input terminal and 8 output terminals and is suitable for connecting incremental encoder types and measurement systems. The device has a short-circuit-proof auxiliary voltage for the encoder supply and distributes the input signals on up to 8 devices. As a special feature, the variant GV480 offers a complete electrical isolation of all input and output circuits against each other (including the supply). This feature, in general, can be most advantageous with impulse distribution among expanded production lines with adverse conditions of EMC / grounding / potential shift etc.

The GV4xx series was discontinued on December 1st, 2023. For new projects we recommend the device GV224 from the new modular GV/GT2xx series.
