GE IS220PPROS1B | PPROS1B | EMERGENCY TURBINE PROTECTION I/O PACK

GE IS220PPROS1B | PPROS1B | EMERGENCY TURBINE PROTECTION I/O PACK.IS220PPROS1B is an Emergency Turbine Protection I/O Pack manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. A backup Overspeed protection system with a backup check for generator synchronization to a utility bus is provided by the Emergency Turbine Protection I/O pack (PPRO) and related terminal boards. They also serve as the primary control’s independent watchdog. Three triple modular redundant (TMR) PPRO I/O packs mounted to a separate simplex protection (SPRO) terminal board make up a typical protection system. Each SPRO is connected to the designated emergency trip board by a cable with DC-37 pin connections on both ens:

TREG: Gas Turbine Emergency Trip Terminal Board.

TREL: Large Steam Turbine Emergency Trip Terminal Board.

TRES: Small/Medium Steam Turbine Emergency Trip Terminal Board.

TREA: Turbine Emergency Trip Terminal Board.

The Mark VIe SPRO or TREA terminal board accepts the PPRO’s direct mounting. Cables with DC-37 pin connections on both ends are necessary between the SPRO board and the chosen trip terminal board when placed on an SPRO board. The following are the installation steps:

Install the SPRO or TREA terminal board firmly. If SPRO is used, mount the chosen trip terminal board.

If TREA is not utilized, connect a cable with DC-37 pin connections on both ends between SPRO and the chosen trip terminal board.

Directly connect three PPRO modules to TREA or one PPRO module to each SPRO.

PPRO’s threaded posts, which are situated on either side of the Ethernet ports, should be slid into the openings in the mounting bracket for the terminal board.

To ensure a tight fit between the PPRO’s DC-62 pin connector and the terminal board, adjust the bracket’s position. Secure the mounting bracket firmly.

Only one adjustment should be necessary during the lifespan of the product. Lock PPRO in place by firmly tightening the nuts on the threaded posts.

Depending on the setup of the machine, connect either one or two Ethernet wires. The PPRO module chooses the appropriate operation over either port and is not sensitive to Ethernet connections.

Connect the module’s power connector, which is located on its side, to power it up. The I/O module has a built-in soft-start feature that regulates current levels when used.
