SCADAPack PLCs & Accessories
Programmable Logic Controllers (PLCs) are computer control systems that detect the state of all input devices connected to it, make a decision based on a user-created program and then, output commands to any devices connected to it. PLCs monitor, control and communicate automated processes and act as the physical interface between devices and a SCADA or HMI system. PLCs are best suited for simpler processes and smaller automation projects that do not require rapid scalability. They are ideal for both simple and high-speed machine control and can be found in assembly equipment, motion control and dispensing systems.
Remote Terminal Units (RTUs) are devices used for remote monitoring and control of automation devices and systems in industrial environments. They serve a similar purpose to PLCs, but to a higher degree. An RTU is considered a self-contained computer with a processor, memory and storage. It can control multiple processes without requiring user intervention or input from a more intelligent controller. RTUs interface with Distributed Control Systems (DCS) and Supervisory Control And Data Acquisition (SCADA) systems.They can monitor a field’s analog and digital parameters through sensors and data received from connected devices and systems, and send the data to central monitoring stations.
