Used in Allen-Bradley DC drive systems, the 117478 is a PC firing board assembly manufactured by Allen-Bradley (Rockwell Automation) and made in the USA. The board carries internal part number 112990 REV04, spare parts kit designation 117478, and MOD number MOD62789. Serial number SN54312 is visible on the label. The board revision is REV04, and the PCB assembly includes connector positions labeled J5 and J9 on the silkscreen. The assembly is a large-format multi-layer PCB populated with through-hole ICs, discrete components, heat-sink-mounted power transistors, and multi-pin edge connectors.

The board was stored in an ESD-protective anti-static bag. Country of manufacture is the United States as indicated on the PCB silkscreen.
