GE IS215UCVGH1A Mark VI UCVG Controller Single Slot VME

Product Summary

The IS215UCVGH1A is a single-slot VME controller from the GE Mark VI series. It uses an Intel Ultra Low Voltage Celeron 650 MHz processor. This board comes with 128MB of SDRAM and 128MB of flash memory. The controller operates on the QNX real-time operating system. It provides two 10BaseT/100BaseTX Ethernet ports for robust connectivity. This unit directly replaces older UCV controllers without a backplane upgrade.

Product Procurement & Buyer Guide

Procurement managers need a reliable upgrade path for aging turbine controls. The IS215UCVGH1A solves this problem perfectly. It is a direct replacement for any previous UCV controller. This means you avoid costly downtime and complex system re-engineering. The board installs into the existing VME rack without any backplane changes. This single-slot design saves valuable space in your control cabinet.

Application engineers require specific technical alignment for their systems. This controller uses an Intel Ultra Low Voltage Celeron processor clocked at 650 MHz. It contains 128MB of SDRAM and 128MB of flash memory for reliable operation. The board requires a +5V dc power supply drawing 4 A typically. It also needs minimal current from the +12V and -12V rails.

The dual Ethernet ports offer critical network flexibility for modern plants. The first port (LAN1) connects to the UDH for configuration and peer-to-peer data. The second port (LAN2) operates on a separate IP subnet for Modbus or EGD networks. This separation improves network security and data traffic management. The controller validates its toolbox configuration against hardware on every power-up.

Communication with operator interfaces happens through multiple channels. The board includes two COM ports for RS-232C serial connections. COM1 handles initial system setup and configuration tasks. COM2 communicates with distributed control systems (DCS) as a Modbus slave. The front faceplate also features a SVGA monitor port and a keyboard/mouse port.

The controller mounts on a Versa Modular Euro (VME) rack for physical stability. It communicates with I/O boards through the standard VME bus. Some board types support local I/O via PCI Mezzanine Card (PMC) daughterboards. The QNX operating system ensures high-speed and high reliability for industrial applications. The Control System Toolbox loads the specific software for your application.

Expert Technical Evaluation & Performance Review

The IS215UCVGH1A delivers exceptional processing power for a single-slot board. The Intel Ultra Low Voltage Celeron processor operates at 650 MHz. This provides sufficient speed for real-time turbine control algorithms. The 128MB of SDRAM ensures smooth multitasking and data handling. The 128MB of flash memory stores the operating system and application software.

Environmental tolerances meet the demands of harsh industrial settings. The board operates within a temperature range of 0 to 70° C. This allows installation in control rooms with standard climate control. The board size is compact at 2.8 cm high by 8.6 cm deep. The unit weighs only 0.45 kgs for easy handling during installation.

Network performance is a key strength of this controller. The two Ethernet ports support 10BaseT and 100BaseTX standards. This provides flexibility for connecting to older and newer network infrastructure. The first Ethernet port enables peer-to-peer communication with other controllers. The second port supports Modbus TCP or a private EGD network. This dual network capability isolates critical control traffic from business networks.

The controller uses the QNX real-time operating system for deterministic performance. QNX is a multitasking OS designed for high-speed industrial applications. This ensures the controller responds to events within predictable time frames. The system validates its configuration against the hardware on every power-up. This prevents errors from mismatched software and hardware configurations.

Power requirements are efficient for a board of this capability. The +5V dc rail draws 4 A typically with a maximum of 5.4 A. The +12V and -12V rails draw less than 1mA each. This low power consumption reduces heat generation inside the control cabinet. The board includes four LED indicators on the front faceplate. These LEDs provide immediate visual status of the controller's operational state.
