Adlink's PCI-7442 DIO card

Adlink Technology Inc. has announced a high-pin count, opto-isolated DIO card featuring 64 digital input and 64 digital output channels. Designed for applications requiring scores of I/O controls and superior digital output driving capability, Adlink said the PCI-7442 is suitable for compact machine controllers, large-scale test and measurement devices, relay control and automation systems.

Packed in a universal, 32bit PCI form factor with plug-and-play capability, the new module implements an open drain power MOSFET circuit in each of its 64 digital output channels, enabling each channel to handle currents up to 300mA. All its digital input lines are identical, non-polar and isolated from each other to facilitate fast and accurate input collection, even in noisy environments. Its I/O channels also come with up to 1250Vrms isolation voltage to protect the host system from damage due to voltage surges and external current.

The PCI-7442 also provides a 32-channel TTL I/O that can collect TTL signals and a board ID design that allows convenient card identification on systems with multiple cards installed. Promoting precision control, the device incorporates a change of state function that senses any sharp change in the logical state of any digital input and notifies the user of the change via an interrupt request. This card is also equipped with safety functions, including programmable power-up DO status and a watchdog timer. The programmable power-up DO status enables the user to set the DO status after a hot system reset; providing vital DO status reference and preventing execution of random and unexpected commands, the company explained.

Supporting Microsoft Windows and Linux operating systems, the PCI-7442 also comes with software drivers for widely used application development environments, including Visual Basic, Visual C, BCB, Delphi, LabVIEW and MATLAB.
