Description:

IS215WEPAH2AB module in my training data. It's possible that this module may be a less common or specialized component within GE's product lineup. To obtain accurate and detailed information about the IS215WEPAH2AB module, I recommend referring to the official documentation, technical specifications, or contacting GE directly for the most up-to-date information.

On turbines that do not have a mechanical overspeed bolt, the control can issue a trip command either from the main processor board to the VTUR board in the control module(s) or from the backup protection module. Hydraulic trip solenoids are wired with the negative side of the 24 V dc/125 V dc circuit connected to the TRPG which is driven from the VTUR in the control module(s) and the positive side connected to the TREG which is driven from the VPRO in each section of the backup protection module. A typical system trip initiated in the control module(s) will cause the analog control to drive the servo valve actuators closed to stop fuel or steam flow and de-energize (or energize) the hydraulic trip solenoids

from the VTUR and TRPG. If cross-tripping is used or an overspeed condition is detected, then the VTUR/TRPG will trip one side of the solenoids and the VPTRO/TREG will trip the other side of the solenoid(s).

A VSVO board provides four servo channels with selectable current drivers, feedback from LVDTs, LVDRs, or ratio metric LVDTs, and pulse rate inputs from flow divider feedback used on some liquid fuel systems. In TMR applications, three coil servos are commonly used to extend the voting of analog outs to the servo coils. Two coil servos can also be used. One, two, or three LVDT/Rs feedback sensors can be used per servo channel by selecting low, medium, or high in the software.
