General Electric Mark VI IS200STTCH2A is a DIN Rail Mounted Thermocouple Terminal Board. The IS200STTCH2A is mounted on a DIN rail. DIN rails are a common type of mechanical support installation that can sometimes be used to connect to the chassis ground. There aren't many components on the board. Lines of capacitors, resistors, and ferrite beads dominate the board's center, which is typically utilized as high-frequency noise suppression devices. This has a 48-position terminal strip on one side. The strip is split into two halves, each with 24 screw connections. Wires can be connected or terminated to the board quickly and easily using terminal strips.
One cable connector is located in the center of the other side of the board. This is a female DC connector with 37 positions. The board's only integrated circuit (U1) is located on one side of the board surface.
For identification purposes, the board has multiple codes, including 6BA00 and 94V-0.
