Product Description

The GE IS420UCSBH3A is a UCSB Controller Module for the GE Mark VIe control system and MarkStat applications. It is a standalone controller designed to execute application-specific control logic and provide network communication with the Mark VIe I/O architecture. GE documentation identifies the UCSBH3A as a 1200 MHz controller with five Ethernet ports, one USB port, and one COM port, while GE certification documentation lists the IS420UCSBH3A as a Mark VIe or MarkStat controller using a 1200 MHz EP80579 Intel processor. The controller architecture allows access to I/O network data without relying on a conventional backplane-based controller arrangement.
