IOC-DO64-VME-A (Digital Output)

The IOC-DO64-VME is a high performance, 64 channel, VMEbus, digital output board with built in test features. The board was designed with high reliability, low power consumption and low cost in mind. Each channel is independent and can be powered externally. An externally controlled fail safe shut off is available on the front panel to support safety critical applications.


  • 64 optically isolated outputs with
    • Up to 55 VDC Operation
    • Fully Independent Channels
    • Single Pole Solid State Relays
    • 1000 Vrms, 60 Hz channel-to-VMEbus isolation
    • 500 Vrms, 60 Hz channel-to-channel isolation
    • Externally controlled failsafe channel disable
  • VMEbus slave (A24/D16)
  • Built-In-Test support
  • Front panel output connections
  • Operating temperature range of -40 to +85C
  • Designed to meet MIL-STD 810E Vibration and Shock Methods 514 and 516
  • Relative humidity range of 0 to 95% noncondensing
  • Conformal Coating Standard


This board is designed to be very rugged and low cost while packing the maximum number of highly isolated channels in a single slot. This attention to design detail keeps the system function cost low while providing superior reliability. In addition, the board can be factory configured with any arbitrary mix of TTL and Solid State Relay channels, up to 64 total, for applications where optical isolation isn’t required on all channels. These features, along with inherent safety features combine to produce a low cost solution for systems where safety and cost are important.


  • Vcc: 5V typical
  • Icc @ Vcc = 5V: 0.7A (off), 2.5A (on – all 64 outputs active)


  • VxWorks driver available
