What an RTU controller is
An RTU (Remote Terminal Unit) is an industrial telemetry controller that links field equipment to server software. Inside a remote shutoff device, the RTU receives valve open/close commands, drives the electric actuator and streams the unit's state to the monitoring system in real time.
Communication and integration
- 4G LTE and 5G cellular, SIM and eSIM — a reliable channel in any region of Uzbekistan;
- Receives commands from the gas utility's billing system through an API interface;
- Integrates with automated gas control and metering systems and SCADA;
- Electromagnetic compatibility per O'z DSt 2821:2014.
Archives and logs
The RTU keeps hourly and daily valve state archives (open/closed), a timestamped log of commands and their execution, and records anti-vandal cabinet openings — a tamper signal reaches the software instantly with the exact event time. This data forms the evidence base for dispatching and incident review.
Power and build
The controller runs on 12 V DC with the option of a solar panel controller and a backup battery of 20+ Ah, so the device stays controllable during outages. Intrinsically safe build, rated −40 to +60 °C at up to 98% humidity.
The RTU in the ERKSONS ecosystem
The RTU controller is the connective tissue of our industrial IoT solutions: it serves smart gas valves, feeds telemetry to our gas monitoring software and slots into our telemetry and SCADA architecture. Contact us — we will help select controllers and design the communication system for your device fleet.
The RTU within the certified solution
The RTU controller is the connecting link of smart gas infrastructure: it ties the certified TimeWave DN50–DN300 valves to the monitoring software over 4G LTE and industrial IoT technologies. Real-time telemetry, the command log and automatic gas supply control operate as one system and integrate with corporate platforms — billing, SCADA, 1C and SAP.
