[PU202]
[PU204]
  • PU 202 is a level converter for incremental encoders  from HTL (A,B,Z, 10-30V) to TTL and RS422 standard levels, max. frequency 200 kHz. The unit can also translate different standards of direction signals to the quadrature standard (see drawing) Power supply 5 VDC
  • PU 204 is a level converter for incremental encoders from TTL-RS422 standard to HTL (A,B,Z, 10-30V) level , max. frequency 200 kHz. The unit can also  translate quadrature input signals to other standards of direction signals
    (see drawing). Power supply 10-30 VDC
  • Both units are available as open p.c. boards with a frame for DIN rail mounting

PU210*: Universal Level Converter and Potential Separator
for Incremental Encoder Signals

[PDF manual]
  • Signal inputs A, /A, B, /B, Z, /Z adjustable to TTL/RS422 level or to HTL (10-30V) level
  • Signal outputs  A, /A, B, /B, Z, /Z (push-pull), output level depending on remote voltage (Vext. = 5 – 30V)
  • Potential separation between input and output by high-speed inductive coupler
  • Suitable for conversion of a A/B quadrature direction signal to a static direction signal and vice-versa
  • Connection by choice via SUB-D-connector or via screw terminal strips
    (parallel circuit)

GV210*: Dual Universal Level Converter (no galvanic separation)

[PDF manual]
  • Universal encoder interface, applicable as dual level converter, encoder splitter and encoder cross switch.
  • Two encoder inputs A, B, Z, and  /A, /B, /Z, each individually adjustable to either TTL/RS422 level or to HTL (10-30V)  level.
  • Two signal outputs A, B, Z and  /A, /B, /Z, likewise individually adjustable to either TTL/RS422 or HTL (10-30V) level
  • Contactless and bounce-free switch-over between the encoder channels, by remote 24 volt control signals.
  • Power supply 12-30 volts DC, auxiliary output 5 volts (2x125mA)  for supply of incremental encoders
