PCI-7256
16-CH Latching Relay Outputs & 16-CH Isolated DI Card
Digital I/O
Introduction
ADLINK's PCI-7256 is a 16-CH latching relay outputs and 16-CH isolated DI card. All relays are Form C type, which
are suitable for device connection with ON/OFF control. With latching relays, the PCI-7256 has the advantage of power
saving. The status of each latching relay output is represented by an onboard LED. When the relay is in SET condition,
its corresponding LED will turn ON, and on the contrary, it is OFF. Latching relays also features unchanged status even
when the system power is turned off, so that the PCI-7256 is suitable for critical applications which need to keep output
status when fault conditions happen.
All digital input channels are non-polarity, optically isolated, and may be set to use RC filter or not. The PCI-7256 also
features a change-of-state (COS) function that generates an interrupt when any digital input changes its state.
