The Ellenex RM4-L is a 4-channel, low-power LoRaWAN transmission interface for industrial applications. It connects up to four existing wired sensors or instruments to a LoRaWAN network from a single battery-powered, outdoor-rated node.

Key features

• Four input channels on one node
• Built-in replaceable 3.6 V lithium battery, with an optional 12 VDC external power input
• Typical battery life of 50,000+ readings and 20,000+ transmissions, per the manufacturer datasheet
• IP66 or IP68, UV-protected ASA enclosure for outdoor installation
• Sampling period configurable by downlink (default 4 hours); periodic or event-triggered sampling
• Works with the main LoRaWAN network servers, including ChirpStack, The Things Network, Kerlink, TEKTELIC, Loriot, Netmore and AWS

Input options (per ordering code)

• 4 x 4-20 mA
• 4 x 0-10 VDC
• 4 x mV or mV/V
• 4 x Pt100 / Pt1000 temperature (2 or 3 wire)
• 4 x pulse (reed switch)
• 4 x SDI-12
