How to use the Relay Output Module of Industrial Shields

Introduction

On this post it is shown how to correctly use the Relay Output Module of Industrial Shields.


Requirements

Relay Output Module                  Relay Output Module


Description

This module is thought for using a digital 12Vdc output to activate relays. The modules consists of 10 relays and 10 inputs interconnected between them. When the input I0.X detects a HIGH value, the corresponging relay output RX will close the circuit, being X any value between 0 and 9. This process is completely implemented by hardware. There is no software that interacts with this Relay Outputs Module.


General Features


*The output current is divided in all 10 relays. If all 10 relays are working at the same time, the output current per relay will be 0,08A.


Schematic

When looking at the schematic, there are some things that must be taken in consideration.

The left part of this module is for the relay outputs. The supply that will be in the Relays connectors will be the one that is implemented in the VCOM(+) and COM(-). All VCOM(+) amd COM(-) are interconnected. This means that there is only 1 VCOM(+) and 1 COM(-) different signals. The right part shows the inputs. The inputs are all referenced to the same GND connectors.
