SAB-QS

Synchronous Quadrature Converter

Overview

The SAB-QS is a two channel module that converts change in magnetostrictive transducer position to the AB quadrature format and is synchronized to the host controller via strobe inputs.

Description

The SAB-QS is a two channel module that converts change in magnetostrictive transducer position to the AB quadrature format and is synchronized to the host controller via strobe inputs. The conversion is implemented with a micro-controller and EPLD allowing a wide range of flexibility and high-speed output. When commanded by the host controller, the module interrogates the magnetostrictive transducers and outputs any change as the correct number of state changes on the AB quadrature lines. Quadrature changes are output in a burst fashion upon receipt of the strobe input. The strobe input used by the host controller to synchronize the updates of the transducer can also be used to signal that the absolute position of the transducer is to be output via the quadrature lines. Each channel has a transducer OK relay output to signal the proper functioning of the transducer. A setup mode allows easy setup of transducer type and recirculations via the RS232/RS485 port

Features

  • Two channels of 24-bit position from Start/Stop, PWM, or SSI magnetostrictive transducers
  • Fast quadrature output of up to 1,500,000 counts per second on two channels
  • Transducer updates are synchronous with a host controller using the strobe inputs
  • Strobe inputs can cause absolute position of each channel to be output
  • Transducer OK relay output and LED signals valid transducer operation
  • Convenient screw terminal connections
