ICP Electronics Australia is proud to introduce ICP DAS PCI-TMC12AU. The PCI-TMC12AU is a sophisticated timer/counter board designed for versatile applications in both industrial and laboratory settings. This board stands out with its Universal PCI interface, compatible with both 3.3 V and 5 V PCI buses, ensuring broad compatibility across various systems.

Equipped with four onboard 8254 timer/counter chips, the PCI-TMC12AU offers 12 independent 16-bit timers/counters. These timers/counters can be further cascaded to create 32/48-bit timers/counters, offering enhanced precision and flexibility for complex timing and counting tasks. The board boasts 12 external clock input channels and the same number of timer/counter output channels, facilitating intricate timing and control operations.

Further enhancing its functionality, the PCI-TMC12AU features a more flexible interrupt mechanism with four interrupt sources. It incorporates two internal clock sources, providing reliable timing references. Additionally, the card supports a gate input that can be sourced either externally or from a previous timer/counter output, adding to its versatility.

For digital interfacing, the card is equipped with 16-channel, 5 V/TTL digital input and output, supporting a wide range of digital devices. The inclusion of Card ID support via an SMD switch and DO status readback functionality enhances the ease of integration and monitoring.

Notably, the PCI-TMC12AU is a direct replacement for the PCI-TMC12A, offering seamless transition without the need for software or driver modifications. It also includes a hardware mechanism to generate two starting clocks, broadening its application scope.

Compliance with CE, UKCA, FCC, RoHS, and WEEE standards ensures the PCI-TMC12AU meets rigorous quality and environmental standards, making it a reliable choice for professional applications. Its design is particularly suited for tasks such as pulse/event/switch-toggle counting, frequency readings, elapsed time measurement, pulse-width measurement, PWM output, and pulse (square wave) and rate generation.
