Safety Controllers

Safety controllers are special purpose devices designed to provide critical control and safety during potentially dangerous process situations. They are specially built to reduce risk and meet safety requirements.

How do safety controllers work?
Safety 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.
Safety controllers are designed for interfacing with safety components such as light curtains in applications like robotics, press controls and material handling systems.

What are safety controllers used for?
Safety controllers are used in various applications in the automobile industry, steel industry and energy sector, as well as in the food and beverage industry. They also have a critical role to play in systems that safeguard a process to prevent catastrophes such as the release of toxic chemicals.
