GE IC3600SIXM1A1A Speedtronic Mark I-II Printed Circuit Board

The GE IC3600SIXM1A1A is a printed circuit board (PCB) associated with the GE Speedtronic Mark I-II turbine control system. It provides a hardware interface for electrical connections within the control assembly. Its board dimensions and connector arrangement are useful identification points when checking an existing card for maintenance or replacement.

Connector Layout and Identification

The board has a rectangular layout with electrical connectors positioned along one edge and near the center. Available product information identifies the following physical features:

• A black connector marked 218A4637P4 / 87936-3.
• A secondary black connector marked 218A4637P1 / 87936-1.
• Two red multiport jack connectors, with 2-port and 5-port configurations.

These markings help technicians compare the physical board configuration during replacement checks. Connector appearance alone does not establish pin assignments or electrical compatibility.
