• Corresponding to the high voltages (24 - 48VDC) I/O.
  
• A different external power supply can be used for each common pin as it is shared by 16 channels.
  
• The PCI bus (personal computer) and the I/O interface are isolated from each other by an opto-coupler, offering good noise immunity.
  
• You can use all of the input signals as interrupt inputs.  You can also select the interrupt trigger edge of the input signal.
  
• The board has a digital filter feature to prevent noise or chatter from causing erroneous inputs.
  
• Up to 60 VDC, 100 mA per signal, max. output.  Zener diode connected to output transistors for protection from surge voltage.  Overcurrent protective device provided for every eight channels of output transistors
