SIGM-U3550 – Fanless In-Vehicle PC

SIGM-U3550 – Rugged 4U fanless in-vehicle computer

Railway-certified system for transportation, telecommunications, and industrial automation

SIGM-U3550 from JHC Technology is a rugged, fanless 4U in-vehicle computer based on the PICMG CompactPCI Serial standard (CPCI-S.0 R2.0). The system is designed for extreme environments such as railway, marine, and aerospace applications, delivering high reliability, wide voltage support, and modular expandability through a 9-slot CompactPCI Serial backplane.

With an Intel® Coffee Lake-H CPU, onboard memory, dual display output, and a 1+1 redundant 300W DC power supply, the SIGM-U3550 is ideal for mission-critical edge applications in transportation and automation.
