Safety Relays
Safety relays are a vital part of industrial and commercial applications. They ensure machinery and processes operate safely and soundly within the safety parameters established for them. Safety relays monitor and control safety functions. They work in tandem with devices like light curtains, emergency stop buttons, and a safety mats to detect and respond to conditions that might just be too risky and could escalate into a situation that would be dangerous for personnel. When the safety relay senses a potential problem, it activates force guided contacts or positive guided contacts that do two things: first, they interrupt the machinery operation, making it stop and not go any further, and second, they prevent any accidents that might occur from human error by ensuring that the unsafe machine is not unsafe anymore.
Safety relays are highly versatile and compatible with a range of safety devices and systems. They are an integral part of many machine safety solutions. Safety relays constantly monitor the inputs and outputs of a device. When a safety system is tripped, the safety relay performs a risk evaluation before allowing the device to enter a safe state. If the system passes the evaluation, the relay lets the device continue operating under normal circumstances.
