FUNCTIONAL DESCRIPTION:
IS230SPROH1A is an Emergency Protection Terminal Board manufactured and designed by General Electric as part of the VIe Series used in GE Distributed Gas Turbine Control Systems. The Emergency Protection (SPRO) terminal board is equipped with a PPRO I/O pack, which processes speed signal inputs for the pack. It features a pair of potential transformers (PTs) to handle voltage inputs from both the bus and generator. Additionally, it has a DC-37 pin connector next to the PPRO I/O pack connector, allowing a connection to the backup trip relay terminal board. The SPRO also supports the direct mounting of a PPROH1A and provides a DC-37 connector for linking to the chosen backup trip relay terminal board.
INSTALLATION:
The SPRO and a plastic insulator are mounted on a sheet metal carrier that attaches to a DIN rail. Alternatively, the SPRO and insulator can be mounted on a sheet metal assembly that bolts directly into a panel. Speed signals and PT inputs are connected to the terminal block using standard #18 AWG wires. The SPRO1A barrier terminal block is detachable for easy board replacement, while the SPRO1A Euro-block terminal block has removable terminals for the same purpose. The I/O pack installs directly onto connector JA1 of the SPRO, and a DC-37 pin conductor cable connects to JA3, linking the SPRO to the chosen backup trip terminal board.
OPERATION:
Terminals 19-24 are designated for three-speed inputs, while terminals 7-15 are allocated for potential future control feature expansions and are connected to the JA1 PPRO connector. Terminals 5-6 and 16-18 are not connected to the board. The JA1 and JA3 connectors serve as connection points for the PPRO and the trip terminal board cable.

What is the function of the SPRO terminal board?
The SPRO terminal board is designed to condition speed signal inputs and manage voltage inputs from both the bus and generator through its pair of potential transformers (PTs). It also facilitates connections to a backup trip relay terminal board.
How are the speed signals connected to the SPRO terminal board?
Speed signals are wired directly to the terminal block of the SPRO using standard #18 AWG wires. The speed inputs are connected through terminals 19-24.
What types of terminal blocks are used on the SPRO?
The SPRO1A uses a barrier terminal block, which is removable for easy replacement. The SPRO1A uses a Euro-block type terminal block, with removable terminals for board replacement.
