The increasing complexity of machines and plants makes PLC wiring between controllers, sensors and actuators a real challenge. Conventional point-to-point cabling between a programmable logic controller and the field elements is very costly, both in terms of installation and commissioning. In order to save costs, space and time when building control cabinets, we offer you our universal PLC interface system as an efficient alternative. In addition to the range of pre-assembled cables, front adapters and interface modules, we offer interface units and customised wiring concepts that can be perfectly integrated into your systems. Benefit from PLC and DCS wiring solutions without field level adaption.
