Motrona GT228 Incremental Encoder Splitter 8 Output Channels TTL/HTL Selectable Cascade Port

1.55 LBS
Current Stock:

Product Description

The GT228  Incremental Encoder Splitter provides total Galvanic Isolation between all the inputs (A,/A, B,/B, Z,/Z), the power supply, and all outputs one against each other.  Several units can be cascaded together (FK47 Ribbon Cable) and using the Encoder Select Function.  

For a power supply use the GDA18-24A 24Vdc/750mA or GDA18-12A 12Vdc/1.5A.

Pulse splitter with 1 encoder input and 8 potential separated outputs
