Put field serial devices, I/O and sensors on the network. Choose by site conditions: wired control, many serial ports, long-range wireless or vibration monitoring. ETH-A2E, ETH-A2N and ETH-A2L share the same A2 I/O expansion modules.
Field I/O, IF-THEN rule engine, web SCADA and cloud connectivity in one unit; existing equipment goes online unchanged.
Six-plus-one serial ports distributed from one unit; two independent LAN ports span two network segments.
Licence-free band links scattered points without cabling; one master serves eight remote stations, with repeaters indoors.
Dedicated to HY-VT vibration sensors; ISO 10816-3 zones and health scores are computed in the gateway.

Pick by the main requirement on site; projects often mix them, for example a wired master with LoRa remote stations.
Tell us about the equipment on site, the distances and your supervisory system, and we will suggest models and an architecture.
