About the IC3600LRDH1A
The GE FANUC component marked IC3600LRDH1A is a Relay Driver card for the Mark I or Mark II series from General Electric. These two systems were the first of the Speedtronic gas or steam turbine management systems released by GE. Both have now been used for decades to manage heavy-duty gas turbine systems in all sorts of configurations, from single unit 4000 hp systems at use in remote piping stations to full power stations with a combined cycle rating of up to 400 Mw. The MKI and MKII are designed with redundancies on control functions like temperature control and speed. These intentional redundancies improve the overall reliability of the system.
The IC3600LRDH1A carries the GE “USA” logo. It carries its unique board identification number, the codes 003/04, 002/03, and 006/06, along with the number 68A999536. A single edge has been numbered. The board has been marked “STAR” near one corner.
The IC3600LRDH1A carries eighteen transistors. It uses metal film resistors placed individually and in lines of four, and several lines of fixed vacuum capacitors. The board also has multiple diodes. Diodes may not be marked with a prefix.
Fifty-one metal pins are attached in a single line to the surface of the IC3600LRDH1A. These pins are used for communication. When the board is inserted into the framework of the Speedtronic system, the pins are attached by wires to the rest of the system, which allows for the transfer of information. Technical support for this board was provided by GE. End-user publications like manuals were provided by GE.
