Introduction
ADLINK's PCI/PCIe-7256 features all Form C type relays, ideal for
device connection with on/off control. With latching relays,
the PCI/PCIe-7256 further provides operating power conservation,
while the status of each latching relay output is indicated by
onboard LED. When the relay is in SET, its corresponding LED
lights. Latching relays also feature unchanged status even when
the system powered off, making the PCI/PCIe-7256 suitable for
critical applications requiring output status to be maintained even
under fault conditions. All digital input channels are non-polar
and optically isolated, and may be set for optional use of RC filter.
The PCI/PCIe-7256 also features a change-of-state (COS) function
generating interrupt when any digital input changes state.
