Compact IP67 Ethernet/RFID interfaces
20 January 2017
Turck has recently introduced the compact TBEN-L-RFID and TBEN-S-RFID Ethernet/RFID interfaces with protection to IP67. These I/O modules are said to simplify the direct RFID integration of HF or UHF read/write heads.
The multiprotocol devices bring data from RFID read/write heads in the HF and UHF frequency band via Profinet, Ethernet/IP or Modbus TCP to the controller. Because of their protection levels, switch cabinets are unnecessary and wiring effort is minimised.
With a width of just 32 mm, the ultra-compact RFID module in the TBEN-S design is said to simplify PLC-integration by bringing the mapped RFID data via conventional I/Os to the controller, making writing of function blocks unnecessary.
The Codesys programmable TBEN-L variant is larger, but also provides controller functions and is already able to filter and pre-process RFID data, and link it directly with the control operations of the connected periphery.
