Digital I/O Card

14 Channel Digital Input/Output Card
  • 14 I/O channels; individually configured for TTL level input or output.
  • DIP switch addressable; stack up to 32 modules on the same serial port for 448 I/O points.
  • All inputs incorporate a pull-up resistor to 5-volts, simplifying hookup to switch contacts.
  • Outputs can sink/source up to 25 mA each.
  • Responds to button presses and switch transitions using automatic debounce and typematic repeat with adjustable delay.
  • Decodes 4x4 matrix keypad using auto-debounce and typematic repeat.
  • Turns on/off relays, triacs, switching transistors, etc.
  • One-shot pulse output with user programmable length of 10 to 655,350 ÁS.
  • Wide power supply range (8 to 30 VDC).
  • Optional enclosure also available.

Connects to a PC or Laptop using our USB Cable or to any other host which incorporates an RS-232 serial port. Stack multiple cards together on the same port. Provides 14 distinct I/O channels, each of which can be configured by the user for either input or output at TTL levels. Easy to use command set minimizes learning curve but preserves a robust, feature rich, functional environment. Ideal for quick set-up and run applications. Note, each channel is limited to 0-5 volt TTL level signals with no over-voltage protection. Use our WTX4, WTDIN, or WTDOT series if protection is required or higher voltages are being sensed or switched.
