Alarm Output Relay: One relay contact closure can be configured as normally open, normally closed, or pulsed.
Volage: t30 V Current: 1 amp max.
Sensor Network Cable Length: 100 m maximum
External Power: External power is required. The system optionally accepts the following Onset solar panels:
- SOLAR-1.2W: Watt Solar Panel - for sunny locations and/or locations with low data transfer requirements
- SOLAR-3W: Watt Solar Panel - for moderately cloudy locations, higher latitudes, and/or medium data transfer requirements.
- SOLAR-6W: Watt Solar Panel - for very cloudy locations, higher latitudes, and/or high data transfer requirements.
Alternatively it accepts an AC power adapter:
- AC-U30: AC Battery Charger for U30 - rated for 240V, 50Hz input power
