PRODUCT INFORMATION
Product Overview
The General Electric IS215VPROH2B is a VME protection assembly for Mark VI / Mark VIe control systems. This emergency turbine protection card operates independently to supply emergency overspeed protection for turbines. The circuit assembly interfaces directly with associated TPRO and TREG terminal boards. Trip solenoids connect to the TREG board to execute emergency trip functions.
The assembly consists of two stacked printed circuit boards joined by threaded standoffs and screws. A full-width heat sink and integrated circuits are mounted on the upper printed circuit board. The front faceplate provides an IONet Ethernet port, an Ethernet ID connector, and a parallel port. Five additional D-shell ports and status LED indicators are accessible on the front panel. Conformal coating protects the board components from harsh industrial environmental conditions.

TECHNICAL INFORMATION
Installation Guidelines
- Mount the VPRO assembly into the designated VME rack enclosure.
- Secure all threaded standoffs and front panel retaining screws firmly.
- Connect positive solenoid wiring to TREG and negative wiring to TPRO terminal boards.
TECHNICAL INFORMATION
Compatibility
- Compatible with General Electric Mark VI and Mark VIe turbine control platforms.
- Operates with associated TREG and TPRO terminal boards for trip solenoid handling.
- Supports a single TREG terminal board due to the lower power VPROH2 rating.
- Systems requiring two TREG terminal boards require a VPROH1 assembly instead.

PRODUCT FAQ
Frequently Asked Questions
What is the primary function of the IS215VPROH2B assembly?
The IS215VPROH2B provides independent emergency overspeed protection for GE Mark VI and Mark VIe turbine systems.
Which terminal boards connect to the IS215VPROH2B module?
The assembly connects to TREG and TPRO terminal boards to control turbine trip solenoids.
How many TREG boards does the IS215VPROH2B support?
The IS215VPROH2B is a VPROH2 low power version supporting only one TREG terminal board.
What module is needed if two TREG boards are required?
Turbine control systems requiring two TREG terminal boards must use a VPROH1 module instead.
