Description
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.
Digital ∫ Features
Models include new Digital Integration Features on 8 bits of input and 8 bits of output.
- Inputs: Enhanced Change-of-State IRQs can be enabled on a bit-by-bit basis, with a selectable (rising/falling) edge. Separately enabled per-bit edges are counted with an optional overflow IRQ. Low-side and high-side pulse widths are measured with a resolution as fine as 8ns. These measurements automatically provide both frequency and duty cycle measurements for waveforms up to 65.5 MHz.
- Outputs: Individual rising-or-falling pulses can be generated, individually or simultaneously on up to 8 output bits, with durations controllable with 8ns resolution. Sequential pulses or continuous frequencies (with programmable duty-cycle) can also be output.
- EZUpdate: FPGA supports EZUpdate allowing new FPGA code to be written via software across the PCI Express bus, allowing field upgrade with new features.
