GE IS200SPROH1A Backup Protection Terminal Board

Part Number IS200SPROH1A Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VIe Function Module Availability In StockIS200SPROH1A is a PPRO terminal board developed by GE under the Mark VI series. This device is part of the Mark VI series from General Electric. The Mark VI, like the other Mark series, was created to address all aspects of industrial turbine control. For decades, these systems have been in use across a wide range of businesses. The IS200SPROH1A is a printed circuit card or printed circuit board with a square shape (PCB). 

A big solid black terminal block encompasses the full left edge of the IS200SPROH1A. Two transformers have been linked together in a horizontal row to the right of this terminal block, along the upper edge of the IS200SPROH1A. The bulk of these transformers are red, with yellow and black bits affixed to the top. Two areas just beneath these transformers may accommodate tiny resistors. These resistors have a single black band in the middle and are yellow in color. A total of six rectangular black diodes have been grouped into two vertical rows of three diodes each. Three little solid yellow capacitors are arranged in a horizontal line beneath these diodes.

UNCTIONAL DESCRIPTION:

IS200SPROH1A is a Backup Protection Terminal Board manufactured and designed by General Electric as part of the Mark 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. SPRO accepts direct mounting of one PPROH1A and provides a DC-37 connector for a cable to the selected backup trip relay terminal board. 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.

SPROH1A features 24 barrier terminals in a pluggable block.

SPROH2A features 24 pluggable Euro-style box terminals.

INSTALLATION:

The SPRO and a plastic insulator mount on a sheet metal carrier, which mounts on a DIN rail. Optionally, the SPRO and insulator mount 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 connector JA1 of the SPRO. A DC-37 pin conductor cable plugs into connector JA3 of SPRO with the other end attached to the selected backup trip terminal board.

OPERATION:

In the following drawing, the PT inputs to SPRO are shown on terminals 1-4. 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.
