The ABB 2TLA020054R0300 Tina 4A Connection Block is designed for the series connection of up to four DYNlink devices, providing a reliable and efficient solution for safety circuit integration. It features four M12-5 female connectors, allowing each device's information signal to be wired separately. The connection block is compatible with cables having a diameter of 7 - 12 mm, ensuring flexibility in installation. For optimal performance, any unused M12-connectors should be fitted with Tina 1A blind plugs.
