Model DFA-100 Dual Channel Difference Amplifier

Model DFA-100 Dual Channel Difference AmplifierThe Model DFA-100 Dual Channel Difference Amplifier is intended for differential to single-ended signal buffering and conversion for data acquisition systems in general purpose signal processing and measurement applications. The DFA-100 is suited for industrial control, PLC interface and automotive test and development applications.

Applications

  • general purpose differential signal amplifier / buffer - differential to single-ended conversion
  • industrial controls, process instrumentation, automotive test
  • ground loop elimination
  • current sense amplifier for solenoids, motors, actuators

Model DFA-100 Difference Amp

  • converts two-wire analog inputs to single ended output for A/D converter / data acquisition systems
  • two independent channels: -5V DC to +5V DC input to -5V DC to +5V DC output
    • amplifier also available with gain to x100, contact APM, Inc. with requirements
  • provides over +/- 100V common mode rejection
  • 5V DC powered, low power consumption (< 5mA)
  • eliminates common ground / ground loop issues in control systems and industrial applications
  • economical alternative to commercially available isolation amplifiers (under $150 vs. up to $1000)
  • screw down terminals for easy connection to analog signals
  • small form factor, 3.625in. x 2.25in. x 1.375in., DIN rail mountable
  • also designed for use with APM, Inc. PWM Controllers - all Model 20X and 201-XX versions
    • use with the PWM Controller operated in the Analog Input Mode
  • warranty: guaranteed for 1 year for manufacturer defects
  • Order No.: DFA-100 or DFA-100-DIN
