The TwinSafe Terminals, Beckhoff offers the choice of merely increasing the proved depot system. Transfer the whole cabling for the protection circuit into the already existing field bus cable.
Safe signals is mixed with customary signals while not restriction. this protects style effort, installation and material. Protection is simplified considerably through quicker identification and easy replacement of solely a few parts. The new ELx9xx series Bus Terminals solely embody 3 basic functionalities: digital inputs EL19xx, digital outputs EL29xx and a logic unit EL6900. For an oversized range of applications, all sensors and actuators will be wired on these Bus Terminals. the desired logical link of the inputs and also the outputs is handled by the EL6900. for little to medium-sized configurations, the tasks of a fail-safe PLC will therefore be handled among the depot system.
