A [email protected] is an optional accessory for Huber units with Pilot ONE.
The [email protected] provide the following interfaces:
- Analogue interface (AIF) for 4-20 mA communication
- POKO (volt-free contact / floating contact)
- ECS (external control signal)
- RS232/RS485 (serial)
- The external [email protected] also has a level interface (to connect an external float switch, for monitoring the level of an externally closed application).
These are in addition to any interfaces already on the Huber unit. A [email protected] is always required if you need an analogue interface.
