How to use SLC 500 4-Channel Analog I/O Modules?

PLC users are familiar with SLC500. In 1991 the output of products was focused on medium-scale industries. In 1993 these products began uses Ethernet communication TCP / IP that are now widely used. There are several kinds of SLC5 / 01 communication controllers port used such as DH485, SLC5 / 02 with a communication port DH485, SLC5 / 03 with a communication port DH485 and RS232, SLC5 / 04 with a communication port DH + and RS232, SLC5 / 05 with a communication port Ethernet and RS232. PLC of this kind is now no longer manufactured. PLC Type SLC500 is equivalent to the CompactLogix. The software used to design, download, and upload programs that RSLogix500. For those of you who still use or want to learn PLC this type, it could follow the following guidelines:

Basic Knowledge Types of Analog Modules

Before you learn more about SLC500, you have to know basic knowledge of various analog modules as below:

1746-NI4 Analog Input Module

Normally this PLC has 2-4 analog input channels. In this case, the 1746-NI4 Analog Input module contains 4 analog input channels.  This port is key control system to support a variety of monitoring and controlling applications to get reliable performance of control system yields.

1746-NIO4I and NIO4V Analog Combination Modules

Single slot module has used in the NIO4I and NIO4V Analog Combination I/O modules. To support this controller, there are two input and two output channels. One device to be checked before used is input voltage. This PLC has two current or voltage inputs. It is same with N14 1746 analog modules that has two current or voltage inputs (user selectable per channel) and two voltage outputs.

1746-NO4I and NO4V Analog Output Modules

The NO4I and NO4V Analog Output Modules is more complete analog output module. It has also 4 analog output channels but using four current outputs to support high performance control system requirements. The NO4V is set to be used on variety of monitoring and controlling applications

SLC 500 4-Channel Analog I/O Modules

Quick Start for experienced technicians

For those of you who have experienced this PLC then there is a quick way that you can use to get started using this module is to how to interpret the ladder logic instructions required to generate the electronic signals to control the performance of your control system.
Some supporting devices needed to run the quick start are:
  • Screwdriver and a small knife for the installation of communications cables (Belden ™ 8761)
  • Laptops are compatible with the programming language of the PLC's

You run the procedure that should be able to follow the following guidelines:
Ensure that your controller hardware is equipped with:
  • Analog I / O module (Catalog Number 1746-Series) , Link Download :
  • Installation Instructions (publication 1746-IN008), Link Download:

If something is missing please contact your local Allen-Bradley representative for further proceedings.
  • Measure the power requirements for the modular PLC controller to support the placement of the analog module.
  • If you use a modular style systems, you can use the reference instructions in the SLC 500 Modular Hardware Style User Manual
  • For fixed SLC 500 controller, you should understand the basic principles of programming language that refers to the SLC 500 Fixed Hardware Style Installation & Operation Manual
