Wireless sensor actuator interface for PROFIBUS networks The cost-efficient alternative for fieldbus communications with movable system parts.
The Weidmüller wireless sensor actuator interface (SAI) modules form a wireless I/O communications network and thus completely replace drag lines containing bus cables or interference-prone slip-ring assemblies. This increases machine availability and reduces maintenance costs, e.g. for replacing defective drag chains or worn slip-ring assemblies. The gateway module can be directly integrated in the bus network without a bus coupler and is directly addressed via the respective configuration interface (e.g. Simatic Manager). Various slave modules with digital and analogue inputs and outputs are available and enable exact adjustment to the requirements of a given application. A total of 6 slave modules can be operated at one gateway.
