Product Description


The 803624-4D is an SP500 Power circuit board from Reliance/Rockwell Automation.  This board is designed to fit into SP500 drive systems that feature NEMA 1 or 4/12 enclosures.  The motors have start/stop/reset control and feature forward/reverse ability, along with drive diagnostics.   SP500 drives are PWM (pulse width modulated) drives that operate on single- or three-phase power.  Reliance components like the 803624-4D were sometimes marketed under company names ABB or Baldor-Reliance.

The 803624-4D mounts within the SP500 drive directly above the IGBT module.  It is a generally-rectangular board with several small tabs extending from two sides.  One side has a small tab cut into its surface.  The circuit board is drilled in several places to allow for mounting hardware.   Components on its surface include a ten-position terminal strip, two female vertical pin connectors, a male vertical pin connector, two transformers of different sizes, and an LED component.  The board also has high-voltage electrolytic capacitors, ceramic capacitors, diodes, resistors, integrated circuits, transistors, metal oxide varistors,  field effect transistors, and Zener diodes.  The board also has a number of stab-on connectors that are connected to a metal block that is located below the circuit board, and two two-pin vertical connectors. 

More detailed information about the 803624-4D can be found through technical support publications that arrived with your OEM purchase.  This includes data sheets and user guides.
