The safety module and safety relay are electronic devices used for monitoring and controlling safety equipment in industrial automation systems. They are usually integrated into PLCs (Programmable Logic Controllers) or DCSs (Distributed Control Systems) to achieve safety functions such as emergency stop, safety door monitoring, and safety light curtains.

The full module and safety relays are indispensable safety components in modern industrial automation systems. They monitor and control safety equipment to ensure the safety of equipment and personnel. In practical applications, based on specific safety requirements and system configuration, choosing the appropriate safety module and safety relay is the key to ensuring the safe operation of industrial automation systems.
