Introduction
ADLINK's PCI-7250/7251 provide 4-CH SPDT (Form C) & 4-CH
SPST (Form A) relay outputs and 8-CH isolated digital inputs. The
LPCI/LPCIe-7250 and cPCI-7252 provide 8-CH SPDT (Form C) relay
outputs and 8/16-CH isolated digital inputs. The status of each 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. All digital input channels are nonpolarity, optically isolated,
and may be set to use RC filter or not. The devices are suitable for
collecting digital inputs in noisy environments.
The PCI-7251 is an 8-CH relay outputs and 8-CH isolated DI
extension card of the PCI-7250. All the I/O functions of PCI-7251
are the same as those of the PCI-7250. The PCI-7251 has to be
connected with PCI-7250 and the bus interface is controlled by
the PCI-7250. Up to three PCI-7251 cards can be connected to one
PCI-7250, therefore, expanding the PCI-7250's DIO from 8 DIO to
maximum 32 DIO.
