Relay W808

This document is a technical schematic for the Digital Equipment Corporation "Relay W808" circuit board. It illustrates the layout of two identical control circuits, each utilizing a DEC6534D transistor, a Wheelock 268-2A-12 relay, and various diodes and resistors. The diagram provides the necessary electrical configuration for operating these circuits between +10V, -15V, and ground rails. It also includes a conversion chart for the transistors and diodes, alongside standard component specifications (1/4W resistors, 10% tolerance) required for test and maintenance purposes.
