32 Input Encoder Position Capturing Coprocessor

    The TIO-1 is a high speed, quadrature encoder position capturing, 32 channel digital input module. Whenever any of the 32 inputs changes state, the current state of all the inputs, along with the current encoder position are latched. The sample rate is faster than 2 µ-seconds, and the board has a hardware FIFO capable of latching 512 sets of samples. The on-board C programmable processor reads the data from the hardware FIFO. It can then do numeric processing on the data, and pass the results of the calculation through either ethernet or a RS232C port, to a PC or PLC.

  • Quadrature encoder inputs (5 volt differential A+/A-/B+/B-)
  • Buffered encoder outputs (5 volt differential A+/A-/B+/B-)
  • Encoder speeds up to 5 Million counts per second
  • 32 channels of 24VDC inputs with 2 µS response time (Opto Isolated)
  • 24 Bit quadrature position register
  • Hardware FIFO with enough depth for 512 samples. (special order up to 8,192 sets of samples)
  • C programmable co-processor for unloading FIFO and processing data
  • Communications over ethernet or RS232C to PLCs
  • Socket communications over ethernet to a host PC
  • RS232C port
  • Ethernet I/O
  • Battery backed non-volitile memory
  • HTTP web server can be implemented on co-processor
  • Communicate with web browser java applet through a socket
  • Encoder may be substituted with an internal time base, for high-speed, time-stamped applications
  • Terminal Block J1

    1 - Encoder Display Unit

    When switching from 12 digit display mode to 6 digit display mode, the lower order 6 digits in the current count for the Y axis are preserved. It expects to see only a single phase change at one time, and the signals to change state at a rate of less than 7 million times per second. The default operating mode is 12 digit single axis mode, until the X zero button is pressed, at which time we switch to dual 6 digit mode.


    Quadrature Encoder Optical Isolator and Splitter

    It is possible to use 3 different isolated power supplies as well (one for the physical encoder, and one for each of the virtual encoders). The inputs and each of the outputs can get power from a different power supply, and they are optically isolated from each other. It takes a A+/A-/B+/B- encoder input, and splits it off into 2 independent A+/A-/B+/B- sets of encoder outputs.
