GE VME-PMC-CADDY Expansion adapter board

Description

Product Overview

The GE VME-PMC-CADDY is a professional industrial VME bus carrier and expansion adapter board. It is a core compatible hardware component of GE VME-based industrial control and turbine control systems. This module acts as a bridge between standard VME bus racks and PMC (PCI Mezzanine Card) expansion modules. It effectively expands system hardware scalability and functional diversity. It is widely deployed in GE Mark VI, Mark VIe turbine control systems and various industrial embedded control equipment.

Traditional VME control racks face obvious functional expansion limitations. They cannot directly install PMC standard auxiliary modules. This restriction limits system function upgrading, signal expansion and customized transformation. It is difficult to meet the multi-functional and high-expansion operation demands of modern power generation and automated industrial systems. To solve this industry problem, the GE VME-PMC-CADDY adopts standard VME-PMC adaptive architecture. It supports flexible installation of multiple PMC modules and realizes seamless conversion between VME bus and PMC interfaces. Every product undergoes strict compatibility testing, signal stability calibration and long-term full-load aging screening before delivery. It supports plug-and-play installation and system renovation, and fully adapts to standardized global industrial e-commerce procurement modes.
