Industrial sensors, I/O, and edge platforms
This page is a orientation guide for teams aligning telemetry and digital-twin work with what plants already specify: IEC-friendly power (often 24 V DC), isolated I/O, industrial temperature ranges, and EMC behavior that consumer-grade IoT was never designed for. It is not a shopping list, reseller catalog, or endorsement. Selection stays with your integrators, EPCs, and procurement rules.
Why “industrial grade” matters
- Environmental — IP ratings, conformal coating, and extended operating temperature vs. office Wi‑Fi gadgets.
- Electrical — isolation, surge tolerance, and deterministic fieldbus or OPC-UA paths—not always applicable to consumer IoT clouds.
- Lifecycle — decade-long revision control and spare compatibility matter for OT Capex; vendor roadmaps are part of risk registers.
- Security posture — segmentation ideas from ISA/IEC 62443 apply regardless of whose gateway sits at the edge.
Representative product families (public vendor pages)
Links point to manufacturer or product-line documentation so you can verify specs independently. Many lines are sold through industrial distributors online; that availability does not imply Ashton resells or prefers any brand.
| Category | Typical role | Example families |
|---|---|---|
| Edge / industrial PC | Protocol translation, local buffering, VPN endpoint near the line | Siemens Industrial Edge, Advantech edge / WISE |
| Remote I/O & gateways | Bring digital/analog signals from skids into Ethernet without PLC rewires | Moxa remote I/O, Phoenix Contact Axioline F |
| Smart sensors & IO-Link | Parameterizable sensing, diagnostics, and Device diagnostics over masters | ifm IO-Link ecosystem (masters, hubs, sensors) |
| Protocol conversion / edge analytics | Modbus, OPC-UA, MQTT toward your historian or cloud landing zone | Red Lion FlexEdge (example multi-protocol edge) |
Collaborators, not competitors
In delivery we work with your chosen automation partners—system integrators, OEM panel shops, and your IT/OT security owners. Authority comes from traceable configuration, encryption, and alignment to standards, not from naming inspection firms or benchmarking unrelated service providers.
