About the IS215VPROH1B
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. This IS215VPROH1B device's greater Mark VI Turbine Control System Series is one of the final-developed GE Mark product series to make use of this patented Speedtronic control system technology. The Mark VI Series that this IS215VPROH1B device belongs to, as you can probably decipher based off of its above-included full extended series name alone, has a set of specific applications intended for the control and management systems of popular, General Electric-compatible wind, gas and steam turbine automated drive assemblies.
Hardware Tips and Specifications
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. This IS215VPROH1B modular assembly is actually not the original product of its intended functionality manufactured for the Mark VI Series, as that would have to be the IS215VPROH1 parent Emergency Turbine Protection Module notably not utilizing this IS215VPROH1B product's singular B-rated functional product revision.
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. Despite this IS215VPROH1B modular product assembly's possession of a dual-width front faceplate, this IS215VPROH1B device is still considered to mount in the Mark VI Series' standard VME Rack Mounting Assembly, given the compatibility of this IS215VPROH1B device's base printed circuit board. Each of the individual hardware components or LED diagnostic indicators supplied for analysis on this IS215VPROH1B product's VME rack installation faceplate should be accompanied by their own factory-printed nomenclature labels for component identification purposes, as pictured.
