Part I: Introduction and Definitions

Video Transcript:

Course Outline

This is an introductory course on the Kvaser DIN Rail SE400S, organized into seven short sections. The objective is to show how to start up the Kvaser DIN Rail SE400S and make sure the correct connections are used for the separate ground.

The course will also show you how to update the firmware and readout the current version so you can be sure that all modules have been updated.

Part 1: Introduction

What is DIN Rail? A DIN Rail is a metal rail of a standard type widely used for mounting circuit breakers and industrial control equipment inside equipment racks. They are a universally interchangeable rack-mounting system used across a wide selection of industries.

‘DIN’ is an acronym that stands for Deutsche Institut für Normung, which translates into English as ‘German Institute of Standards’. Devised originally in Germany in the late 1920s, the name DIN became the official symbol for technical standardization in Germany in the 1970s and has become commonplace for automation equipment to be mounted on 35 millimeter DIN rails ever since.

Throughout the course we will use a series of acronyms for the Kvaser DIN Rail modules.

Part 2: Definitions

Regarding ground and signal ground and protective earth, ground is equal to 0 Volts; ground is not equal to protective earth in this material, ground can be power ground or signal ground in this document.

Regarding insulated versus isolated, isolated simply means to be apart from each other, usually things, while insulator is the barrier used to isolate those things. To insulate is to prevent current leakage between two conductors. Coaxial cables are a great example of both insulation and isolation.
