1/2 Size Synchro PCI Card with 3.3V/5V Universal Signaling


Part Number(s): SB-3624xIx
Package: PCI Card
Lead Free Information: B

The SB-3624XIX-3L0 is a PCI card that contains six channels of fully independent Synchro or Resolver-to-digital conversion. For each channel the conversion process is implemented using a DDC RD-19230 16-bit monolithic converter and a thin-film resistor network or Scott-T transformer. The reference oscillator comes in two variations which support voltages up to 26 Vrms or 115 Vrms with input frequencies from 57 to 7 kHz.

Each channel has an independent solid-state signal and reference input. Transformer isolation is available for 90 V Synchro applications. Signal connections are provided through a 68-pin mini D-type connector (P1). The RD-19230 converter has an incremental encoder output, “A quad B”, which consists of the A, B, and Zero Index (ZI) outputs. Other features include a self-test mode that places predetermined angular values on the input channels, a turns counter to keep track of the number of rotations the synchro or resolver has made, and direction information to determine if the converter is counting up or down.


Applications include modern, high performance industrial and military position feedback and control systems.

Typical motion feedback applications include:

  • Motor Control
  • Machine Tool Control
  • Antenna Control
  • Robotics
  • Gimbal Control
  • Process Control Systems
  • Engineering Development
  • Production Test

The SB-3624XIX-3L0 is supplied with a Windows Graphical User Interface (GUI) and software support for Linux. LabVIEW support for Windows also available.
