The new Profibus extender Phoenix Contact enables the easy integration of remote Profibus devices with data rates up to 1.5 Mbps. The extender has two DSL connections per device. This has the advantage that not only point-to-point connections but also line structures with up to 30 devices can be set up easily.
In order to protect the communication modules, overvoltage protection is required for both DSL connections. The DIN rail-mountable DSL overvoltage protection has two a / b connections per screw terminal. When building a line structure, only one overvoltage protection must be used per intermediate station. This saves space in the control cabinet and is more cost-effective.
