The IP67 Speedway 767-1311 fieldbus coupler links fieldbus communication devices to a Sercos V1.2 real-time Ethernet fieldbus system. The machine-mount coupler features 10µs high-speed synchronization for motion control applications. Its eight digital inputs capture binary signals from switches and sensors with a 10µs (microseconds) scanning cycle that is compatible with 31.25µs Sercos cycles. It can support applications with I/O cycles of a 250µs. The coupler is extendable up to 64 modules, which can be installed away from the Sercos coupler for system expansion up to 200m. This enables digital and analog I/O modules to be installed next to sensors and actuators.
