Isolated Digital Input and Relay Output Card -- 104-IIRO-8-Image
Isolated Digital Input and Relay Output Card

The 104-IIRO-8 is a low-cost card that provides isolated input and output for PC/104 Bus computer applications. The card has eight optically-isolated digital inputs for AC or DC control signals, eight TTL Inputs and eight electro-mechanical relay outputs. An Economy version can be ordered as Model 104-IIRO-8E which has no Change of State Dectection or IRQs.

Features

  • 8 optically-isolated, non-polarized CMOS compatible digital inputs accept ±31VDC or AC rms
  • IRQ on input change of state (COS) eliminates the need for constant polling
  • Slow/fast filter to accommodate AC voltages and noisy DC inputs
  • 8 long-life form C electro-mechanical relays switch up to 1A each
  • 8 non-isolated TTL compatible inputs
  • Factory Options: (call for pricing and availability)
    • Economy version without COS feature
    • Input only and relay only versions
    • Expanded input voltage levels
    • RoHS Available. Please contact us for ordering information
