GV204 

Impulse Splitter for Incremental Encoders 

 

 

 

 

 

Programmable encoder input A, /A, B, /B, Z, /Z, for use with RS422 or  
TTL differential signals or with HTL signals (differential or single-ended) 

 

Two encoder outputs (A, /A, B, /B, Z, /Z each), with individually programmable 
output levels (TTL 5 V or HTL 10 - 30 V) 

 

Max. frequency 750 kHz (TTL) or 300 kHz (HTL) 

 

Power supply either 5 V DC or 10 - 30 V DC 

 

Aux. voltage 5 V for encoder supply (with 10 -3 0V power supply) 

 

Operating Instructions
