Specials:
Level-switches, temperature-switches, pressure-switches, manual operated valves and other equipment, not provided with AS-Interface-electronics, can be connected to the AS-Interface fieldbus by an Instrument-module.

The Instrument-module can supply the necessary power for the instrument.

No special connection cable is needed since the Instrument-module is mounted direct on the cable-entry or DIN-connector of the instrument.

Also according client specifications.
