SIGM-U3550 – Rugged 4U Fanless In-Vehicle Computer with CompactPCI Serial & Redundant Power

Railway-Grade Performance for Transportation, Telecom & Industrial Automation

The SIGM-U3550 from JHC Technology, available at Nord Technology, is a rugged 4U fanless in-vehicle system based on the PICMG CompactPCI Serial (CPCI-S.0 R2.0) standard. Built for railway, shipboard, and aviation environments, it offers extreme durability, wide input voltage support, and modular expandability through 9-slot CPCI-S.0 backplane.

Equipped with an Intel® Coffee Lake-H processor, onboard memory, dual display outputs, and 1+1 redundant ultra-wide DC 300W power supplies, this platform is ideal for mission-critical edge applications in transport and automation.
