IS215UCVCH5A Manufacturer General Electric Country

Part Number IS215UCVCH5A Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI/VIe Function Module Availability In StockIS215UCVCH5A is a Controller Board manufactured and designed by General Electric as part of the VIe Series used in GE Distributed Control Systems. 

The UCVC is available in three forms, UCVCH1, UCVCH3, and UCVCH5. The standard UCVCH1 controller is a double-slot board using a 133 MHz Intel Pentium processor with 8 MB of flash memory and 16 MB of DRAM. A single 10Base2 (BNC connector) Ethernet port provides connectivity to the toolbox or other devices via EGD. The UCVC contains a double column of eight status LEDs. These LEDs are sequentially turned on in a rotating pattern when the controller is operating normally. When an error condition occurs the LEDs display a flashing error code that identifies the problem. 

FEATURES:Control Algorithm 

Execution: Controller boards execute control algorithms responsible for regulating turbine operation, including speed control, load control, and safety protocols. 

Sensor Integration: They integrate various sensors to monitor parameters such as turbine speed, temperature, pressure, vibration, and wind speed (for wind turbines). These sensors provide real-time data to the controller board for accurate control and system protection. Actuator Control: Controller boards manage actuators such as fuel valves, steam valves, pitch mechanisms (for wind turbines), and braking systems to adjust turbine operation according to control algorithms and external conditions. 

Fault Detection and Protection: They incorporate fault detection algorithms to identify anomalies in turbine operation and trigger protective measures to prevent damage. This could include shutting down the turbine or activating safety protocols in case of overspeed, overheating, or other critical conditions. 

Communication Interface: Controller boards facilitate communication with supervisory systems, allowing for remote monitoring, control, and data logging. They often support communication protocols such as Modbus, Profibus, or Ethernet/IP for seamless integration into larger control networks. Redundancy and Reliability: In critical applications like power generation, redundant controller boards may be employed to ensure system reliability and fault tolerance. Redundancy ensures that if one controller board fails, another can seamlessly take over control without compromising system operation. Remote Diagnostics and Maintenance: Controller boards may feature diagnostic capabilities that enable remote troubleshooting and maintenance, reducing downtime and operational costs. They can provide telemetry data and diagnostics to remote operators or maintenance personnel for proactive maintenance scheduling.UC2000/VME P133/2 GE

About the IS215UCVCH5

The IS215UCVCH5 is a GE Mark VI UCV controller.  This component was manufactured by GE to be a part of the Mark VI system, which was released as part of the Speedtronic line of gas/steam turbine management.    The MKVI can be used as either a Simplex or a TMR (triple modular redundant) system, depending on the size, complexity, and needs of the related turbine system.

The IS215UCVCH5 is a controller board with a wide double front faceplate with many components mounted into it.  The board takes up four VME slots. Components in the faceplate include three sets of LEDs (twenty-two in all,) a DLAN+ interface, two Genius Interfaces, two ISBus interfaces, as well as two COM interfaces.   Some of the LEDs on the front panel are labeled Status, flsh, active, ok, enet, and active (2nd.) The OS for this component is QNX, which is a multitasking operating system similar to UNIX. The processor is a 486 100 MHz processor.  Memory on this controller is 8 MB DRAM with 128 KB of level 2 cache.

The Ethernet interface of the IS215UCVCH5 is a 10BaseT connector using TCP/IP protocol to communicate with the toolbox and SRTP (serial request transfer protocol) to interface between the controller and the HMI (human-machine interface.)   The COM1 port located on the faceplate is used for diagnostics only and the COM2 port is used for Modbus communication between the controller and DCS. The component also has a micro-miniature 9-pin socket D connector.
