Digital I/O card PCIe-IIRO-8

with relay outputPCI Express

-Eight optically isolated, non-polarized digital inputs -Switchable filters on inputs for electrically noisy environments -Eight electro-mechanical relay outputs -Optically isolated channel to channel and channel to ground -Can detect input state change and assert interrupt -Automatically detected under Windows -Designed, made, supported, and manufactured in the USA FACTORY OPTIONS -Extended temperature operation (-40° to +85°C) -RoHS compliant version PCI Express Isolated Relay I/O Card This product is a x1 lane PCIe isolated digital input and relay output board with Change of State (COS) detection capabilities. The isolated inputs can be driven by either AC or DC and are not polarity sensitive. Input signals are rectified by a diode bridge and applied to the inputs of opto-isolators. A 470 ohm resistor in series provides current limiting. Standard 12/24 AC control transmitter outputs can be accepted as well as DC voltages. The input voltage range is 5V to 24V (rms). To extend the input voltage range, you may connect external resistors in series. The electro-mechanical relay outputs of the PCIe-IIRO-8 are comprised of five form C SPDT outputs and three Form A SPST (normally-open) type. The relays are all de-energized at power-on. Data to the relays is latched. The card is 6.6 inches in length and 4.2 inches seated height. I/O wiring connections for this board are via a male 37-pin D-sub connector. A ribbon cable can be used to connect this card to termination panels.
