Introduction to PLC-5 Output modules The PLC-5 Output modules control devices. In this post, we will discuss the discrete modules (on/off conditions). The Output modules simply act as a switch to turn on or off a load. Examples of field devices attached to output modules include valves, solenoids, indicator lights, Read More »
Introduction to PLC-5 Input Modules The PLC-5 Input modules read the status of equipment. Examples of field devices that act as real inputs include limit switches, proximity switches, aux. contacts, and push buttons. Input modules are simply voltage testers. When a voltage is detected at a particular point, the status Read More »
Introduction to delaying outputs on and off In this post, I’ll explain delaying outputs on and off can be used in the SLC500 processor. For example: We have a motor with a fan. When a main motor starts, a fan needs to start two seconds later. When the motor is Read More »
Introduction to PLC-5 Structure The PLC-5 Structure was probably the most common Allen Bradley processors in the Industry. Produced in the 1980’s, this processor began to replace the PLC-2. Many industrial sites still widely use the PLC-5 processor. However, these remaining PLC-5 processors are slowly being replaced by the new Read More »
