A field multiplexer system is a simple system for transmitting signals between two remote stations. It has a modular structure and is designed to reduce conventional parallel cabling. A field multiplexer system consists of two identical field multiplexer stations. The field multiplexer exchanges data with the remote station via a remote bus cable. The field multiplexer is the central unit of a field multiplexer station. All the necessary Inline I/O terminals of a station are connected to the field multiplexer.

| Protective circuit | Surge protection (segment supply, main supply, field multiplexer supply); Input protective diodes (can be destroyed by permanent overload)Pulse loads up to 1500 W are short circuited by the input protective diode. |
| Protection against polarity reversal (segment supply/main supply); Parallel diodes for protection against polarity reversal; in the event of an error the high current flowing through the diodes causes the fuse connected upstream to blow. | |
| Protection against polarity reversal (field multiplexer supply); Serial diode in the lead path of the power supply unit; in the event of an error only a low current flows. In the event of an error, no fuse trips within the external power supply unit. | |
