Industrial IoT comparison
Edge RTU vs IoT Gateway
Compare Edge RTU and IoT gateway roles in SCADA retrofit, remote IO and cloud-connected industrial monitoring.
Buyer scenario
An Edge RTU focuses on field signals, point lists and control-room protocols. An IoT gateway focuses on connectivity, payload translation and cloud handoff.
Decision table
| Factor | Edge RTU | IoT gateway | Guidance |
|---|---|---|---|
| Primary role | Collects IO and field protocol points | Moves data to cloud or platform | Many projects use both roles in one package. |
| Buyer language | SCADA, DI/DO/AI/AO, point list | MQTT, API, cellular, device management | Use the term your customer system expects. |
| Hardware focus | Rugged IO and local polling | Backhaul, protocol conversion and security | Quote scope depends on where the data leaves the site. |
Choose Edge RTU when
- The project starts from a point list
- Remote IO and local protocols are central
- SCADA compatibility is the main requirement
Choose IoT gateway when
- The buyer needs MQTT or cloud data
- Cellular or Ethernet backhaul is central
- Payload format and integration are the main questions
Information needed for quotation
- Point list and signal type
- Northbound protocol
- Cabinet power and enclosure needs
- Cloud or SCADA endpoint

FAQ
Which option should I choose for Edge RTU vs IoT Gateway?
Choose Edge RTU when the project starts from a point list. Choose IoT gateway when the buyer needs mqtt or cloud data. SunGene can shortlist hardware after reviewing the site and integration details.
Can SunGene quote both options?
Yes. We can prepare a side-by-side hardware path when the buyer provides the site layout, measured parameters, network preference and expected quantity.
Does this comparison include pricing or guaranteed certification?
No. Pricing and certification depend on the selected hardware configuration and target country, so they are confirmed during quotation.
What technologies are usually involved?
The typical shortlist includes Edge RTU, IoT gateway, SCADA, MQTT. Exact protocol, frequency band and payload details are confirmed before samples are arranged.
