The IS200AEPCH1A is a circuit board assembly designed for installation and use as a replacement part for the GE Speedtonic Mark V system.

The MKV contains timing, systems and controls created to ensure reliable and safe operation of turbines in the steam, hydro and gas industries.

The IS200AEPCH1A is a rectangular card that, unlike many Mak V boards, does not have an attachment panel. 

The board is designed with factory made www.cniacs.com drilled holes located at each board corner for mounting. 

Each of these components is surrounded with conductive material. 

Several other factory drilled holes are located in the body of the board and around the edges of the IS200AEPCH1A.

The S200AEPCH1A typically has an auxiliary or daughter board mounted on a surface near the centre of the main board.

 The two boards fit together using brackets and screw mounts, 

and this auxiliary board houses the FPGA and other integrated circuits, female connector pins, diodes, resistors and capacitors. 

The auxiliary board is labelled with codes such as FA/00 and DCOM.

The IS200AEPCH1A is marked with multiple codes on its face. 

Components are usually labelled with a reference name. 

Components include terminal blocks, jack connectors, integrated circuits, and three fuses.
