With up to 10 external channels/sensors per Opus20. The Opus20 offers the highest fl exibility and excellent value for money, allowing the connection of up to 4 external temperature and relative humidity sensors, as well as 2 further analogue sensors. Intelligent sensors can be integrated via the Opus20’s RS485 interface (e.g. particle counter).

Air flow and differential pressure sensors are typically connected to the Opus20 via the analogue input. In contrast, a maximum of 4 external temperature/humidity sensors are integrated via a digital protocol (UMB). In connection with its LAN capabilities, the Opus20 is able to realize universal measurement networks in real time.

For standard applications the SmartGraph 3 comes into play, and in order to fulfi l the 21 CFR 11 guidelines the well-established and proven SmartControl is available.
