Relay Logic Control Systems (Pre PLC)
The days of Relay Logic control systems are nearly all but gone and I reckon the majority of Sparkies don’t have a problem with that. A control circuit involved literally up to hundreds of relays, cam timers and drum sequencers. Every component needed to be wired up individually, it was a slow process to build and there was a real art to leaving a control board clean and presentable. Fault finding on these boards was also a pain, individual components were tightly fitted into control boards and if a component was faulty, it had to be a complete change out.
PLC & SCADA Systems
Programmable Logic Controllers (PLC) and Supervisory Control and Data Acquisition (SCADA) are types of Industrial Control Systems, both are computer controlled systems which monitor and control industrial processes. These systems came about to increase the reliability of electrical control systems by removing the individual components of the Relay Logic circuits and including them internally in the PLC or SCADA system. As a bonus the installation and maintenance costs have been greatly reduced. There are still sites that used Relay Logic but they are few and far between, generally these control systems will be replaced in plant upgrades.
PLC & SCADA Courses
If you are looking at a role as a Industrial Electrician, it is becoming essential to have knowledge and the experience to install, program, diagnose and fault find these systems. The training courses can be either on-line at your own pace or workshop courses and range from single day basics courses to a 5 day advanced courses.
