Product Details:

INTELLIGENT INSTRUMENTATION PCI-20428W-1AN is a low-cost PCI multifunction DAQ board for general test and measurement systems, and this multifunction daq card provides flexible analog input with programmable gain ranges to capture low-level and standard voltage signals from various transducers. It supports 16 single-ended or 8 differential analog input channels, with switchable gain settings including 1, 10 and 100, which makes it suitable for tiny millivolt signals from strain, thermocouple and pressure sensors. It is widely used for laboratory sensor calibration, small process monitoring, educational measurement experiments, industrial signal logging and legacy test bench renovation. Engineers can configure gain, channel range and sampling parameters with supporting driver software, and the board works well for stable multi-gain voltage acquisition tasks in older industrial PCs equipped with standard PCI slots.

Key specifications and parameters: 12-bit SAR ADC resolution, 16 single-ended / 8 differential analog input channels. Programmable gain options: gain 1, gain 10, gain 100. Corresponding voltage ranges cover ±10V, ±1V, ±0.1V and unipolar ranges. It supports software-triggered sampling and continuous data acquisition. The board adopts standard PCI bus interface, powered by PCI slot power supply. It uses a shielded external connector and can be matched with terminal blocks for safe signal wiring. The operating temperature range is 0 ℃ to 55 ℃, storage temperature -20 ℃ to 70 ℃, 10%–90% non-condensing humidity. Each analog input channel has overvoltage protection to reduce circuit damage caused by signal overload. Status indicators help technicians check bus communication status during commissioning and troubleshooting.

This general purpose sensor sampling board is an end-of-life legacy hardware. We supply fully inspected and tested refurbished units for replacement and maintenance of old measurement and control systems. It can cooperate with signal conditioners, relay modules and terminal accessories to build complete stimulus-response measurement platforms. It is widely adopted in university teaching labs, small batch production testing, equipment R&D verification and legacy industrial monitoring projects. As a cost-effective multi-gain DAQ board, it provides reliable low-level and standard voltage signal acquisition for long-running measurement tasks.
