FUNCTIONAL DESCRIPTION:
IS200TPROH2B is an Emergency Protection Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Turbine Control Systems. The Emergency Protection terminal board(s) (TPROH#C and TPROS#C) host three PPRO I/O packs. The TPRO conditions speed signal inputs and contains a pair of potential transformers (PTs) for bus and generator voltage input. It has three DC-37 pin connectors, each adjacent to the I/O pack connectors. Each DC-37 accepts a cable leading to a Mark VIe backup trip relay terminal board.
INSTALLATION:
The TPRO and a plastic insulator mount on a sheet metal carrier, which mounts on a DIN rail. Optionally, the TPRO 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 TPRO_1C has barrier terminal blocks that are removable for board replacement. The TPRO_2C has a pluggable, Euro-type terminal block with removable terminals. The R, S, and T PPRO I/O packs mount on TPRO connectors JR1, JS1, and JT1, respectively. Three DC-37 pin conductor cables plug into TPRO connectors JX1, JY1, and JZ1 with the other ends attached to the selected backup trip terminal boards.
OPERATION:
Nine-speed inputs are displayed on terminals 31-48. Terminals 5, 9, and 11 offer P24 output for the customer. Terminal 8 (MARET) acts as the return path for the P24 output. The P24 output is derived by ORing the 28 V power supply of I/O packs R, S, and T. If any of the I/O packs are switched off, the P24 V output can still be sourced. If speed inputs are TTL-based, then TB3 terminals are used along with even-numbered terminals 32-48, as displayed

What is the Emergency Protection Terminal Board used for?
The Emergency Protection Terminal Board is part of GE's Mark VIe Distributed Turbine Control Systems. It handles emergency protection by processing speed signal inputs and managing bus and generator voltage signals.
Can the board output P24 V if one of the I/O packs is off?
Yes, the P24 V output is derived by ORing the 28 V power supplies of the I/O packs (R, S, and T), meaning the P24 output can still be sourced even if one of the I/O packs is switched off.
What type of speed inputs does the board support?
The board supports both standard speed inputs and TTL-based speed inputs. For TTL-based inputs, TB3 terminals and even-numbered terminals (32-48) are used.
