Safety relays are crucial in safeguarding both personnel and equipment. This model ensures the integrity of safety functions by monitoring emergency stop buttons, safety doors, and other protective devices, instantly disconnecting power in the event of a fault or hazard. The Rockwell Automation 440R-N23120 Minotaur Safety Relay is a high-performance safety component designed to ensure machine and operator protection in industrial environments. Operating on 24V AC/DC, this dual-channel safety relay features two safety contacts and a monitored manual reset, making it ideal for applications where reliable emergency stop or safety gate monitoring is essential. Engineered for durability and compliance with international safety standards, it enhances operational safety without compromising productivity. 

Working Principle of the Rockwell Automation 440R-N23120, Minotaur Safety Relay – Dual Channel, Monitored Reset

The 440R-N23120 operates using dual-channel inputs to monitor safety devices. When an input signal is interrupted (e.g., an emergency stop is pressed), the relay disables its safety outputs, cutting power to the machine. The monitored reset ensures faults are manually acknowledged, preventing automatic restarts and enhancing safety.
