Turck TBEN-S and TBEN-L block I/O modules with Ex approval

Turck now has Ex approval for its TBEN-S and TBEN-L version IP67 block I/O modules to be used in Zone 2, enabling cabinet-free decentralised automation solutions with IEC Ex and ATEX approvals. This reduces labour costs as well as wiring and commissioning time. When used with IP67 IMC interface devices, it is now possible to have cabinet-free connection of intrinsically safe signals from Zone 0 or 1.

Users must install the TBSG-L, TBSG-S or IMC-SG protective housings when implementing the I/O modules in Zone 2. They provide protection against shock and from sparks caused by unsafe removal of cables. The range of applications with Ex zones includes painting, bottling or pharmaceutical plants as well as food industry and wood processing plants.

The ARGEE field logic control software in the I/O modules enables self-contained applications to be implemented directly in Zone 2. This is particularly useful for retrofit applications because existing controller systems do not have to be changed. Condition monitoring and data analysis via cloud systems can now also be implemented from Zone 2 without the need for a control cabinet.
