It includes plug-in front connector modules that attach to I/O modules and preassembled connecting cables. A flexible model is available for simple wiring inside the control cabinet. LED signaling and signal conditioning from 230 Vac to 24 Vdc options are available. Users can select and order the required version with the TIA selection tool on the company’s website.
