Introduction
The PCL-816 modular DAS card allows you to choose your own customized data acquisition configuration. Its 100 KHz A/D module offers 16-bit resolution with 16 channels of
differential analog input measurement. The A/D module has its own protective cover, ensuring excellent signal shielding and noise immunity. A DB-37 cable connector provides
fully-shielded signal connections to the A/D module. In addition to the standard A/D module, the carrier board has two 64-pin piggyback connectors for additional function expansion
modules. Accepting most sub-modules, this modular system makes customizing and upgrading easy.
