Tina 4A is a connection block for series connection of up to four DYNlink devices. Four M12-5 female connectors for the sensors are available on the device. The information signal of each device can be wired separately. The cable used for the connection to the Tina 4A should have a diameter 7 - 12 mm. Unused M12-connectors on Tina 4A must be equipped with Tina 1A blind plugs. The Tina devices adapt the DYNlink safety circuit in Vital, Pluto and B&R X20 to safety components with mechanical contacts, such as E-stops, switches and light beams/curtains with dual outputs. Tina is available in several versions depending on the type of safety component that is connected to the Vital, Pluto or B&R X20 circuit.
