High-power relay output card

Adlink Technology Inc. unveiled its PCI-7260, which is touted to be the world's first true high-power relay output card for industrial automation and machine control. Each of the card's eight channels is capable of switching 5A current at 250Vac or 5A current at 30Vdc. Its pluggable front-panel connector gives consideration to both carrying high current and easy wiring. In addition, the PCI-7260 provides eight isolated digital input channels with debouncing circuits to eliminate signal jitter.

According to the press release, the most impressive features of the PCI-7260 are its safety considerations. To carry high current over the PCB, the trace space, trace width and copper thickness are carefully designed to follow the guidelines of the EN61010-1 safety standard. A high-power pluggable connector is used instead of the traditional D-sub connector to support an 8A-rated current. Furthermore, said Adlink, the PCI-7260 provides a hardware implemented emergency shutdown function, which lets users switch all relays to a safety state by giving a digital signal to EMG_SHDN input from the front panel.

The PCI-7260 supports 3.3V and 5V Universal PCI Bus, as well as Windows 98/NT/2000/XP and Linux OSes.
