Model Numbers

GV480 Encoder Splitter with 8 Output Channels Input & Output Short Circuit Protection
GV481 Encoder Splitter with 4 Output Channels Input & Output Short Circuit Protection


  • Impulse input (A, /A, B, /B, Z, /Z, TTL level or HTL level) 
  • Potential separation by high speed opto-couplers 
  • 6 output channels, each (A, /A, B, /B, Z, /Z) GV150: all outputs TTL / RS422 GV151 outputs individually programmable to either TTL or HTL level 
  • Frequency range 0 - 400 kHz 
  • Front LED’s for indication of input pulses A, B and Z 
  • Elimination of noise and cross talking on transmission lines 
  • Closed aluminum cassette for mounting in 19"racks or assembly on 
  • DIN mounting rails
