I. Core Positioning

MVME162PA-344SE is a 6U VME dual-high industrial single-board computer (SBC) from Motorola/Emerson, combining the features of -344S (with SCSI) and -344E (wide-temperature ruggedized) into one model. The core is the same as the standard version, while it also has SCSI-2 interface and wide-temperature ruggedization capabilities, suitable for industrial sites with large-capacity storage and harsh environments. Applicable fields: Industrial automation, data acquisition, motion control. Primarily used in systems that require onboard SCSI storage.
