Teledyne Dalsa / Coreco Imaging PCVision PCI Frame Grabber

The Teledyne Dalsa/Coreco Imaging PCVision is a half-size PCI frame grabber engineered for cost-effective machine vision OEM applications. It captures images from analog video sources—interlaced (RS-170, CCIR) and progressive scan (VGA) cameras—with deterministic trigger-to-image reliability. The board features 2 MB of on-board VRAM for simultaneous acquisition and processing while preventing data loss during host transfer. Its 40 MHz triple-channel 8-bit ADC digitizes up to three synchronized monochrome sources or supports six inputs using frame delay mode, with software-selectable anti-aliasing filters (6 MHz or 12 MHz cutoff) and bypass capability.
