Some of the features that can be configured on the Mux include:
The Mux (IFM8-IA) contains four interfaces for external equipment: current loop (isolated 0-20mA, 16 bit, 8 channels), RS-485 (isolated, 960K), Ethernet (dual 10/100 Mb/s.), and 2 relays (each NO/COM/NC). The Mux also has LEDs for Run, Error, and Power.
