Phoenix Contact Radioline Wired Multiplexer

Phoenix Contact’s RAD-RS485-IFS head station enables multipoint I/O multiplexing or Modbus RTU bus coupler operation over a dedicated wired network using Radioline platform I/O. The small form factor, hardened I/O, and the hot-swap functionality make this platform ideal for harsh environments that may not be suited for Inline systems.

In addition, the RAD-RS485-IFS is easy to configure for multipoint I/O mapping using the same method as the wireless Radioline products. No software is required for simple setups, and it uses PSI-Conf software for diagnostics or advanced setups.
