Brake Actuator

This document is a technical schematic for a brake actuator circuit designed by the Digital Equipment Corporation. It details the logical configuration of the circuit, which includes multiple integrated circuits (ICs), transistors, diodes, and capacitors used to manage motor braking functions (labeled as "Lower Break" and "Upper Break"). The diagram also includes a bill of materials (parts list) and a transistor/diode conversion chart, identifying the specific electrical components required for the assembly.
