      Information

      Overview Manuals Common Applications Product Precautions
      Foxboro P0903CW combines configurable colored annunciation, tactile operator keys, audible feedback and numeric entry in a free-standing or mounted control-room assembly.
      • 32 annunciator key positions
      • 16-key numeric keypad
      • Serial / GCIO interface
      • Configurable red, yellow or green LEDs

      The keyboard receives power and GCIO serial communication from the supported workstation or interface arrangement. Application mapping determines lamp color, flashing state, audible behavior and the operator action assigned to every key.

      Important Notice: P0903CW is the serial/GCIO annunciator/numeric keyboard. P0903CV omits the numeric keypad, while P0924TT and P0924WV are USB models.
