Industrial 14 Family of Controllers

This document provides an overview of Digital Equipment Corporation's "Industrial 14" family of programmable controllers, specifically the 14/30 and 14/35 models. These systems were designed to provide reliable, flexible, and economical control for various industrial applications.

Key features and components include:

• Industrial 14 Control Unit: A rugged, NEMA-12 enclosed unit containing the control logic and ferrite core read/write memory. It is designed to withstand harsh industrial environments while providing easy maintenance through modular plug-in components and status indicator lights.
• Input/Output (I/O) System: Features a modular design with optically isolated inputs and transformer-isolated outputs. Each module includes LED indicators for quick fault diagnosis and can be expanded in increments to meet specific application requirements.
• VT14 Programming Terminal: A CRT-based terminal that allows users to create, monitor, and edit control programs using standard ladder diagram symbols. It also provides "force" capability, allowing I/O points to be manually toggled for troubleshooting and startup.
• Internal Functions: The system handles timers, counters, shift registers, and retentive memories internally within the main memory, eliminating the need for additional hardware.
• Computer Interfacing: The controllers include dual communication ports, allowing them to connect to programming terminals and external computers (such as the PDP-8 or PDP-11) for monitoring, data logging, or assistance with startup and diagnostics.
• Application Areas: The Industrial 14 series is suitable for a wide range of tasks, including machining and metalworking, automated assembly, material handling, precise measurement and gaging, and chemical processing.
