NS Series Mode 3
The NS series safety switches, with solenoid and RFID technology, now come with the new mode 3 for safety output activation.
In the versions with mode 1, the OS safety outputs are active when the actuator is both inserted and locked; this ensures that the actuator cannot be extracted with safety outputs activated.
Mode 2 – for specific applications in which hazardous elements have low inertia, and the risk does not persist once the guard is opened – allows the actuator to be released while keeping the safety chain enabled.
In the new versions with mode 3, the functions of modes 1 and 2 are combined: a safety output is active when the actuator is both inserted and locked, while the second safety output is active when the actuator is inserted only. This allows two single-channel independent circuits to be combined in a single device, and to emulate traditional electromechanical interlocking devices with guard locking, without complex machine wiring modifications.
The management of the two channels also includes the inputs, so that multiple devices can be connected in series.
