Rolling out environmental monitoring across many sites is easier with identical units that arrive complete. This pack holds 20 STE2 R2 devices, each with its own temperature sensor and power adapter, and each unit monitors up to 5 sensor values on two RJ11 ports.
Benefits
- No extra parts for rollout: every one of the 20 units ships with a 3 m IP67 temperature sensor and a power adapter with EU, UK and US plugs.
- Choice of network link: 10/100 Mbit Ethernet or IEEE 802.11b/g/n WiFi, with optional PoE power at 60 mA.
- Expandable per site: up to 5 values from daisy-chained 1-Wire UNI sensors such as humidity, CO2 or 4-20 mA.
- Direct detector inputs: 2 digital inputs per unit for dry contacts such as door or flood detectors.
- Central overview: SNMP and XML for existing monitoring systems, plus the free HWg-cloud.com portal for up to 20 devices per user account.
