DS4003 Digital I/O Board

Large number of digital I/O channels

The DS4003 Digital I/O Board provides a large number of digital I/O channels for various applications in rapid control prototyping and hardware-in-the-loop simulation.

  • 96 TTL lines (three 32-bit ports)
  • 3 handshake control lines per port
  • 2 interrupts per port plus one on I/O error

Handling digital I/O channels

In rapid control prototyping and hardware-in-the-loop simulation, many digital signals have to be handled. This means that digital I/O lines have to be controlled. The DS4003 Digital I/O Board provides 96 digital I/O lines grouped into three I/O ports of 32 bits, each with handshake and strobe signals.
