104-DIO-48S

Description:

104-DIO-48S and 104-DIO-24S

Main Features:

  • 48 or 24 parallel lines of 82C55 digital I/O with tristate buffers prevent unintended control of external equipment
  • IRQ on input change of state (COS) eliminates the need for constant polling
  • High sink/source current 64mA/32mA
  • I/O pulled up to 5V for contact monitoring
  • Compatible with Opto-22 and other industry standard I/O racks

 

Factory Options:

  • 82C54 with three 16-bit counter/timers for event counting, frequency output, pulse width and frequency measurement
  • 0 to 70°C and -40 to +85°C versions available
  • Economy version without COS feature
  • Pull-down resistors on I/O lines
  • RoHS Available. Please contact us for ordering information
