IS220PPROH1A GE MKVIe Backup Turbine Protection I/O Pack

Description:

IS220PPROH1A is a Backup Turbine Protection (PPRO) I/O pack developed by GE. The Backup Turbine Protection (PPRO) I/O pack and associated terminal boards offer an independent backup Overspeed protection system, as well as a backup check for generator synchronization to a utility bus. They also serve as an independent watchdog for the primary control. Three triple modular redundant (TMR) PPRO I/O packs mounted to separate simplex protection (SPRO) terminal board or three PPROs put on a TMR TPROH#C terminal board constitute a typical protection system. Each SPRO or TPROH#C is connected to the designated emergency trip board through a cable with DC-37 pin connections on both ends:

The Mark VIe Control PPRO Backup Turbine Protection, Cat. Nos. IS220PPROH1A is intended to be used with accessory terminal board Cat. Nos. IS200TREAH1A, IS200TREAH3A, IS200SPROH1A, IS200SPROH2A, IS200TPROH1C, IS200TPROH2C.


TREG stands for Gas Turbine Emergency Trip Terminal Board.
TREL: Terminal Board for Large Steam Turbine Emergency Trips
TRES: Terminal Board for Small/Medium Steam Turbine Emergency Trips
A different configuration places three PPRO I/O packs directly on TREA for a single-board TMR protection system. For IONet communications with the control modules, the PPRO includes an Ethernet connection.

Functional Description
Two Ethernet ports, a power supply, a local processor, and a data acquisition board are included in the I/O pack. This design simplifies or eliminates much of the previously required instrumentation for connecting to field equipment, as well as improving operational reliability and lowering long-term maintenance costs.
The IS220PPROH1A is utilized in Aeroderivative Turbine Emergency Trip applications and is commonly used with the TREAH terminal board. The component can be connected to terminal blocks that are either barrier or box type. For voltage sensing, the part has field-wiring restrictions that limit cable length to 1,000 feet of 18 AWG wiring. When switching from a BPPB P-Pack to a BPPC P-Pack, the component cannot be auto-reconfigured.
The front faceplate of the part is marked with the component id number and many LED indications. These are arranged in pairs on the front faceplate. PWR/ATTN is the first pair, LINK/TxRx and ENET 1 is the second, and LINK/TxRx and ENET2 is the third. The final component is the IR port, which is placed at the bottom of the faceplate.
The part is equipped with a high-speed processor and two 10
