New, Additional Synchro/Resolver Products

• 175A700 high power synchro booster amplifier

  The series 175A700 is a compact synchro booster amplifier intended for bulkhead mounting. The unit is broadband operating from 115Vrms 60Hz and 400Hz synchro reference power, no DC power is required. 90V L-L synchros or 6.81V resolver signals are converted to 90V L-L synchro outputs with a continuous 25VA output capability. All signal inputs and outputs are transformer isolated.

  Features:

  • Industry standard configuration and pin-out
  • +/-3 arc-minute accuracy
  • 115Vrms 60 and 400Hz reference input
  • Transformer isolated synchro signals
  • Opto-isolated DISABLE input and BIT output
  • No DC power required
  • Short circuit, over-load and thermal protection
  • "locked rotor" protection
  • Drives multiple CT and CDX loads up to 25VA
  • Drives multiple TR loads with Zss as low as 15 ohms

• 175A600 synchro/resolver amplifier

  The 175A600 series is a 2.62" x 3.12" x 0.8" synchro/resolver amplifier module intended for pc board mounting. The analog inputs and outputs can be specified as either synchro or resolver types. The amplifier features high input impedance and delivers a full 5VA making it capable of driving virtually all 400Hz size 8 and size 11 passive or active synchro/resolver loads. The amplifier maintains +/- 4 arc minute accuracy from no load to full load. The amplifier features current limit protection and thermal protection. An integral aluminum top plate on the module provides all the necessary heat-sinking. Unit requires +/- 15V power supplies.

  Features:

  • Synchro amplification/voltage conversion
  • Resolver amplification/voltage conversion
  • Synchro to resolver and resolver to synchro conversion
  • "Locked Rotor" protection
  • Transformer isolated output

• 167C100 coarse/fine two speed processor

  Used for combining the digital outputs of two synchro or resolver to digital converters in a geared mechanical or electrically geared coarse fine two speed system.

  Features:

  • 1:36, 1:18 or 1:9 ratios in same module
  • Up to 19 bit resolution
  • Fast (500ns) parallel operation
  • Automatic misalignment correction
  • Pin-for-pin replacement for the AD TSL1612

• 168F100A synchro/resolver to digital converter

  Features:

  • +/- 2.6 arc minute accuracy
  • All common L-L voltages
  • 47 to 1200 Hz frequency range
  • Tracking to 15rps
  • Pin-for-pin replacement for the DDC SDC634a and RDC634a

• RE-1024 resolver to encoder converter system

  Converts resolver signals to incremental encoder A quad B signals plus a gated Z marker. The unit is fully self-contained; operating from universal 85-265V, 47-440Hz power with the incorporation of a programmable resolver excitation oscillator. The oscillator has four discrete operating frequencies programmed via on-board dip switches and an adjustment potentiometer amplitude control allowing for compatibility with most industrial brushless resolvers. Four different output resolutions can be programmed via on-board dip switches.

  Unit is mounted on a 2.50" x 5.00" printed circuit board with four 0.156 mounting holes. Connections are made via convenient screw lock terminal blocks that accept 12-30 AWG wires.

  Features:

  • Fully self-contained, powered from 85-265V, 47-440Hz
  • Contains programmable resolver excitation oscillator
  • Incremental A quad B + Z outputs
  • TTL/CMOS compatible outputs plus complements
  • Programmable output resolutions 128, 256, 512 or 1024 cycles/turn
