The GE VPROH2B (IS215VPROH2BC) is a crucial component within the Mark VI system, specifically designed as an Emergency Turbine Protection card. This card plays a vital role in safeguarding turbine operations by offering an independent emergency overspeed protection system.

It is part of a triple - redundant setup, where three such VPRO boards are installed in a module separate from the main turbine control system. These boards control the trip solenoids via the TREG terminal board. The VPROH2B has a built - in Pentium processor, along with 16 MB of DRAM and 256 KB of Level 2 cache, enabling efficient data processing and decision - making for protection functions.

In terms of power, it can handle a 125 VDC power supply. It features multiple input and output interfaces. There are three analog current inputs and nine thermocouple inputs, which are often utilized for exhaust over - temperature protection in gas turbines. The card also has five D - shell ports for various connections and an Ethernet interface (thinwire 10base2) for IONet communication with the control module, facilitating seamless data exchange and system integration.

The VPROH2B controls twelve relays on the TREG board. Nine of these relays are grouped into three sets of three, which are responsible for controlling the three trip solenoids. In the event of an emergency, such as an overspeed situation or an emergency stop signal, the card quickly activates the appropriate relays to trip the turbine, thereby preventing potential damage to the turbine and associated equipment.

The card operates within a temperature range of 0 to 45 degrees Celsius, ensuring reliable performance in typical industrial environments. With its robust design and essential functionality, the GE VPROH2B (IS215VPROH2BC) is a key element in maintaining the safety and integrity of turbine systems in power generation plants, industrial facilities, and other applications where turbine operation is critical.
