IS230SPROH2A is a Backup Protection Terminal Board manufactured and designed by General Electric as part of the VIe Series used in GE Distributed Gas Turbine Control Systems. The SPRO terminal board hosts a PPRO I/O pack. It conditions speed signal inputs for the PPRO and contains a pair of potential transformers (PTs) for bus and generator voltage input. It has a DC-37 pin connector adjacent to the PPRO pack connector that accepts a cable leading to a Mark VIe backup trip relay terminal board.


The SPRO and a plastic insulator are mounted on a sheet metal carrier, which is mounted on a DIN rail. Optionally, the SPRO and insulator are mounted on a sheet metal assembly, which bolts directly into a panel. Speed signals and PT inputs are wired directly to the terminal block using typical #18 AWG wires. The SPROH1A barrier terminal block is removable for board replacement. The SPROH2A Euro-Block type terminal block has terminals that can be removed for board replacement. The PPRO I/O pack mounts directly on the SPRO connector JA1. A DC-37 pin conductor cable plugs into connector JA3 of SPRO with the other end attached to the selected backup trip terminal board.


Three-speed inputs are shown on terminals 19-24. Terminals 7-15 are reserved for future control feature expansion and are routed to the JA1 PPRO connector. Terminals 5-6 and 16-18 have no board connection. The JA1 and JA3 connectors provide locations for PPRO and the trip terminal board cable.

What are the electronic ID parts in the SPRO and backup trip relay terminal board?

The board and the backup trip relay terminal board feature electronic ID parts, which store specific information about the hardware configuration.

How are these electronic ID parts utilized during power initialization?

During power initialization, the electronic ID parts are read by the system. This information is crucial for the PPRO to verify the presence of a valid hardware arrangement before commencing normal operation.

What purpose does this information serve in the PPRO?

The information obtained from the electronic ID parts allows the PPRO to confirm that the hardware arrangement is consistent with the expected configuration. This verification step ensures the integrity and compatibility of the system components before engaging in normal operational procedures.
