Product Description
GE IS420UCSBH4A — Mark VIe UCSB Standalone Controller

The GE IS420UCSBH4A is a high-performance UCSB (Universal Standalone Controller) module developed by General Electric for the Mark VIe control system. It is also designed for use in GE EX2100e excitation control systems and LS2100e static starter applications.

The controller uses an Intel EP80579 processor operating at 1066 MHz to execute application-specific control logic and communicate with distributed I/O modules through GE's IONet Ethernet network.

As a standalone, panel-mounted controller, the IS420UCSBH4A provides reliable processing, industrial communication, and system integration for demanding power-generation and industrial automation applications.
