Signal Isolator / Signal Converters

Signal Isolator

 

Signal Isolator – Series – 405, 406

Features

  • Eliminates ground loop problems
  • Accepts signals from field sensors
  • High accuracy & Low Temp. drift
  • Many versions available with bipolar input & output
  • 2, 4, 8, 16 channels module available
  • High response time on request (2-10 ms)
  • Long functional life
  • Power CN – indication by LED

Applications

  • To eliminate the noise coming from field sensors, motors, due to wiring
  • To isolate field instruments from costly instruments like SCADA, DCS, PLC, controllers etc.
  • To distribute the signal in 2, 3, 4 outputs
  • To increase the noise immunity of systems
  • For impedance matching of field instruments and panel instruments
  • To use as multiplier / repeaters
