I-87082W
2-channel Counter/Frequency Input Module
 
   
 
Model: I-87082W  
 
  • 2-channel Counter/Frequency Input
  • 32-bit Counter
  • Isolated or Non-isolated Input
  • Programmable Alarm Output
  • Programmable Digital Filter
  • Programmable Threshold Voltage Level
  • Maximum Frequency of up to 100 kHz
  • Dual Watchdog
  • Wide Operating Temperature Range: -25 to +75°C
 
The I-87082W offers 2 high speed counter or frequency input channels and 2 digital output channels. Two types of digital input are provided, one for isolated input, and the other is for nonisolated input. The isolated input provides 3750 Vrms isolation voltage and the non-isolated input provides programmable threshold voltage level. The built-in digital filter is valid for both non-isolated and isolated input and can filter out noise where the high/low pulse width is smaller than the minimum high/low width of the digital filter. The maximum count is up to 32-bit and the maximum frequency is up to 100 kHz. The module also provides programmable alarm output with non-isolated open collectors.
