PCM-3718HO is a fully multifunctional card with PC/104 interface, 16 analog inputs, one analog output, two 8-bit digital I/O channels, and a free counter function. Such a broad range of functions available in a single PC/104 card is a significant breakthrough, and will be appreciated by embedded systems developers with demanding space requirements.

Using the compact PC/104 form factor, the card enables better integration and can be fitted in smaller systems such as the UNO-2160 embedded industrial PC. “The PC/104 form factor is suitable for system integrators that needs more functions in less space, like machine makers”, said Richard Yu, product manager at Advantech. “PCM-3718HO covers many of the functions commonly needed in machine automation, so we think this product will be well received by our customers.”
