The Advantech PCL-81601 is a modular data acquisition card built for industrial measurement and control in demanding environments. It combines a 16-bit ADC with 100 kHz sampling capability, 16 differential analog inputs, 16 digital I/O channels, and two expansion slots for functional modules. The metal-shielded A/D module and DB-37 connector deliver signal integrity critical to noise-sensitive applications.
