AIO-1200 provides 12 Analog Input ports. Each port can measure 0 ~ 20 mA or 4 ~ 20mA currents. AIO-1200 is used to interface with 3rd party sensors/detectors: (1) Temperature and Humidity, (2) Flame proof H2 gas detector, (3) Flame proof O2 gas detector, (4) Flame proof CO gas detector, etc.

AIO-1200 can receive the input current values using (1) MQTT/WiFi, (2) WiFi and (3) LoRa techniques. Method (1) transmits MQTT messages from the remote MQTT broker directly. Methods (2) requires MQTT server and method (3) requires LoRa MQTT Gateway to relay the received messages to the MQTT Server. Messages processed in the MQTT Server can be displayed in the remote PC monitor via a private VPN link.
