RXA15101E - 151MHz Long Range Analog Receiver
The Elsema RXA15101E 151MHz Long Range Analog Receiver provides stable, long-distance wireless monitoring and control up to 5km line-of-sight. Designed for industrial and agricultural applications, it features 1 analog channel (4–20mA sensing) plus 1 digital relay output, making it ideal for pumps, irrigation, machinery monitoring, environmental sensing and remote automation. With secure dip-switch pairing, narrowband FM reliability and strong performance through steel and concrete environments, this receiver is suited for demanding sites where standard frequencies fall short.
Includes:
- Genuine Elsema RXA15101E Receiver (in enclosure case)
- Installation Instructions
Note: This product is for the Australian market. A modified frequency is required for New Zealand, US and Canadian Market (please contact us for more information). This item is not available for sale in other countries due to frequency regulations.
Key Features:
- Dual Signal Support – 1 analog channel (4–20mA, 10-bit accuracy) plus 1 digital channel (normally open contact).
- Long Range Operation – Up to 5 km line-of-sight for remote monitoring and control.
- Secure ID Matching – 12-way dip switch for transmitter/receiver pairing ensures reliable, interference-free operation.
- Superior Industrial Performance – 151MHz frequency penetrates congested environments with steel construction better than higher frequencies.
- Multiple Frequency Selection – Provides flexibility for secure communication across multiple setups.
- Durable Enclosure – Supplied in a protective case for long-term industrial use.
- Easy Setup – Includes external supply connection and SO239 antenna socket for straightforward installation.
Ideal Applications:
- Industrial Automation – Wireless monitoring and control of machines, conveyors, and plant equipment without the need for costly wiring.
- Remote Pump & Irrigation Systems – Reliable long-distance monitoring and operation of pumps, tanks, and valves in agriculture and water management.
- Mining & Heavy Industry – Stable signal performance in steel-structured or underground environments where higher frequencies (433/915MHz) struggle.
- Security & Access Control – Integration with gates, barriers, and alarm systems requiring both analog data feedback and digital triggers.
- Environmental Monitoring – Collecting 4–20mA sensor signals (temperature, pressure, humidity, etc.) from remote or hard-to-reach locations.
- Lighting & Utilities Control – Wireless switching and monitoring for floodlights, industrial lighting, and utility systems over large areas.
