This is a technical schematic diagram for the CC.EF.C.7.12 component (Serial Number 3678927), produced by Westover for the Gannon Air Force Base. The drawing depicts an electronic circuit configuration with multiple functional blocks and interconnections.

The schematic shows a b3 851 module serving as the central processing unit, with input/output status registers and three separate output stages (labeled 1, 2, and 3) each producing discrete voltage outputs. A Smart Sensor module provides input signals including SMVR, RET, and S parameters. The circuit includes multiplexed output configurations (stages 4&5) with specific pin assignments for both positive and negative voltage outputs, alongside open and close functions. Two identical external component assemblies are connected to the main circuit, each featuring 150V/87.5mA specifications with KV and TCV switches. The drawing is identified as Drawing 044 of 210 in a larger technical documentation set, indicating this is part of a comprehensive system specification package for Gannon Air Force Base fuel cell and support equipment used in the New Mexico area, dated December 2015.
