IS215VPROH1B

Product Description

The IS215VPROH1B is a module manufactured for the Mark VI system.  The Mark VI is a gas/steam turbine management system from the Speedtronic line, which has been developed by GE for over thirty years with a focus on creating systems that are reliable and efficient.

The IS215VPROH1B functions as an Emergency Turbine Protection module.  The IS215VPROH1B offers speed difference detection and backup synch check protection.  The board accepts thermocouple and analog inputs. This module has two circuit boards stacked one on top of each other.  The top board is an IS200VPRW board that mounts to the lower board via four screw connections threaded into standoffs. The board is populated by integrated circuits, a transformer, several transistors, as well as resistors, capacitors, and diodes.  Capacitors include those made of polyester vinyl. Resistors are sometimes made of carbon composite material. The board has several inductor coils and many connectors including plugs. There is a heat sink located to the right front side.

The bottom board of the IS215VPROH1B has two backplanes. It has capacitors and resistors and multiple integrated circuits.  This includes oscillating chips. Standoffs for the top board are placed near the edges of the board.

The IS215VPROH1B controls trip solenoids through the TREG board.  Application software within the controller is used to initiate tests of these trip solenoids.  These can also be manually tripped.

The IS215VPROH1B is built with a faceplate.  The faceplate has LED indicators, a power switch, cable connectors, and Ethernet connectors. This faceplate connects to the boards using screws.  More information about this module can be found using publications from the original equipment manufacturer.
