Description
The GE IS200SPROH1ACC is a backup protection terminal board for the Mark VIe control system. It provides interfaces for the PPRO I/O pack, conditions speed input signals, and accepts generator and bus voltage signals through onboard potential transformers (PTs). Its DC-37 connector supports cable connection to a backup trip relay terminal board, while dedicated terminal assignments separate voltage inputs, speed inputs, and reserved control connections.
Functional Overview
The IS200SPROH1ACC supports signal acquisition for speed monitoring and generator-bus synchronization functions. Its onboard PTs provide isolated voltage signals for use by the associated control hardware. The board also provides a physical interface for exchanging signals with the Mark VIe backup trip relay terminal board.
Speed Inputs and PPRO Interface
The board connects to the PPRO I/O pack, which processes speed-related input signals. Terminals 19-24 are assigned to speed inputs, while terminals 7-15 are routed to the JA1 PPRO connector for designated or reserved control functions. Terminals 5-6 and 16-18 have no board connection according to the supplied description.
Generator and Bus Voltage Inputs
Two single-phase potential transformers provide voltage sensing for the generator and bus. Each PT has a nominal secondary output of 115 V rms, with an input loading requirement below 3 VA. The specified synchronization voltage range is 75-130 V rms.
Each PT input has a 1,500 V rms magnetic isolation barrier. The stated wiring capability is up to 1,000 ft using 18 AWG cable. These conditions should be checked against the system wiring design and applicable Mark VIe documentation before installation.
Terminal Mapping and Connectors
The supplied terminal assignments identify the following connections:
| Terminal or Connector | Function |
|---|---|
| Terminals 1-4 | Potential transformer (PT) inputs |
| Terminals 5-6 | No board connection |
| Terminals 7-15 | Reserved control connections routed to JA1 |
| Terminals 16-18 | No board connection |
| Terminals 19-24 | Speed inputs |
| JA1 | PPRO I/O pack connection |
| JA3 | Backup trip terminal board cable connection |
| DC-37 connector | Interface for the backup trip relay terminal board |
Verify connector assignments against the installed board revision and its wiring documentation before connecting field wiring.

Frequently Asked Questions
Q: What is the function of the IS200SPROH1ACC?
A: It provides termination and signal interfacing for the Mark VIe backup protection arrangement, including speed inputs, generator and bus voltage sensing, and the backup trip relay terminal board connection.
Q: What voltage signals does the board support for synchronization?
A: The supplied specifications identify two PT inputs with nominal 115 V rms secondary outputs and a synchronization voltage range of 75-130 V rms. Each input has a loading requirement below 3 VA and a 1,500 V rms magnetic isolation barrier.
Q: What should be checked before replacing this terminal board?
A: Confirm the complete part number, connector layout, terminal assignments, and associated PPRO hardware. Do not assume that another IS200SPROH1A revision or a similar SPRO terminal board is a direct replacement without verifying the applicable hardware documentation.
