531X305NTBAMG1

Product Description

The 531X305NTBAMG1 is a General Electric Motors and Industrial Systems replacement part.  It is typically used within GE drive or GE exciter cabinets.  This board functions as an interface board, and includes several terminal strips for inputs and outputs. 

The 531X305NTBAMG1 is designed to provide the attached control device with several external signal-level inputs and outputs.  This includes regulated and unregulated power outputs with noise-filtering for driving digital encoders.  It also had a differential A quad B encoder interface (optically isolated) that can be connected to the drive.   This can be configured for +5V or +/-15V encoders using jumper switches located on the board’s surface. 

The 531X305NTBAMG1 also has low-level analog I/O scaling through four potentiometers on the board’s surface.  There are also digital control inputs.  These use jumpers to bias unconnected inputs to +/-24 VDC depending on whether positive or negative logic is being used.    Finally, the board includes RS-232C and RS-422 interfaces and several relay outputs.  It also has test points on the board’s surface for testing critical signal paths.  Additional configurable hardware beyond the aforementioned jumpers and potentiometers is limited to DIP switches.  Information about their settings can be found within GEI-10020B.
