The National Instruments TPC-2515 is a robust Touch Panel Computer designed to serve as an effective human-machine interface (HMI) within industrial environments. Built on an x86 platform, the TPC-2515 operates seamlessly with Windows operating systems, including Windows XP and Windows XP Embedded. This model is powered by a low-energy Intel Celeron M processor, available in clock rates of 600 MHz or 1 GHz, and features a BIOS with 4 Mbit of flash memory. The TPC-2515 is engineered without fans, minimizing dust circulation within the system. It boasts a 15-inch TFT LCD that offers a maximum resolution of 1024 x 768 (XGA) and supports up to 256,000 colors, enhanced by a reliable backlight for optimal visibility.

For versatile connectivity, the TPC-2515 is equipped with multiple I/O interfaces, including three serial ports (RS232 and RS422/485), two USB 2.0 ports, a CompactFlash slot, a PCMCIA slot, two RJ-45 Ethernet ports, and a PS/2 port for keyboard and mouse connections. Additionally, it features three audio ports: one line-in, one line-out, and one microphone input. The device operates on a typical power requirement of 24 VDC at 2.0 A. Although the TPC-2515 has been designated as obsolete by National Instruments, it remains available for purchase and repair through Apex Waves.
