For Automation & Control Systems, especially in industrial processes, safety is paramount. Safety Automation Controllers are special purpose devices designed to provide critical control and safety during potentially dangerous process situations. They are built exclusively to reduce risk and can be programmable to suit varied and specific requirements.
How do safety controllers work?
Safety automation controllers contain plc i/o modules that enable them to interpret signals from process sensors and trigger control elements. They work by continually monitoring the status of inputs to detect any malfunctions or failures that may indicate a problem in the machine or in the production/manufacturing process as a whole.
Some safety automation controllers may include a fieldbus option for monitoring processes via commonly used digital communication systems including EtherNet/IP, Modbus TCP, EtherCAT, Profinet, Profibus, CANopen, Modbus RTU.
Safety controllers are designed for interfacing with safety components such as
Light Curtains
Laser Scanners
Mechanical Switches
Emergency Stop Push Buttons
Safety Mats
