Turck TBEN-L4-16DXP Compact Multiprotocol I/O Module

The Turck TBEN-L4-16DXP Compact Multiprotocol I/O Module for Ethernet provides sixteen universal digital channels configurable as PNP inputs or 2 A outputs, enabling flexible decentralized I/O across automation networks. It supports PROFINET, EtherNet/IP, Modbus TCP, and CC-Link IE Field Basic, with two 4-pin M12 D-coded Ethernet ports that operate at 10/100 Mbps and an integrated Ethernet switch to simplify network topology. Powered from 24 VDC nominal (18–30 VDC) via a 7/8" 4-pin male power connector and using M12 signal connectors, the unit is housed in a glass fiber reinforced enclosure rated IP65, IP67, and IP69K for harsh industrial environments. Operating temperature ranges from -40°C to +70°C, making it suitable for conveyor systems, packaging machinery, assembly lines, and material handling equipment that require reliable, distributed digital I/O control. Common replacements listed for upgrade or retrofit include Turck TBEN-L5-16DXP, TBEN-L4-16DIP, and TBEN-L4-16DOP. Its 16 universal digital channels can be configured to support various I/O schemes, enabling scalable expansion across distributed automation without changing other fieldbus wiring.
