Toroidal current sensor ARF819 series

DIN railAC4-20 mA

Product overview
The CURRENT SENSOR is a ready-to-use LoRaWAN device combining the ANALOG transmitter and a current transducer (50 A, 100 A or 500 A) to measure AC current and report values over LPWAN for monitoring and analysis.

Highlights of the IoT sensor

• 2 analog inputs, independently configurable as 0-10 V or 4-20 mA
• 2 digital dry-contact inputs associated with the analog channels
• Data transmission: periodic and/or event-driven (LoRaWAN EU863-870)
• Battery-operated with replaceable 2600 mAh cell
• IP67 enclosure for outdoor/industrial use
• Compatible with Adeunis device management (KARE)

What the connected sensor does

• Monitor energy production and installations by measuring current
• Track and analyse consumption patterns for preventive maintenance and reporting

Alert / Alarm functions
AND/OR Trigger alarms when:

• configured high and/or low current thresholds are exceeded
• an event occurs on one of the 2 dry-contact inputs
