Industrial IoT Remote I/O


As an IIoT I/O module, ATOP’s IO5202 Series is a compact solution for connecting digital and analog devices and sensors, enabling you to monitor, acquire and process data from remote sensors and control digital and analog outputs. The IO5202 Series is a cost-effective solution for integrating existing applications into an IIoT framework, such as automated manufacturing, building management and control, and agricultural and irrigation systems.

The IO5202 Series supports Modbus TCP/RTU/ASCII, MQTT, MQTT over TLS and SNMP. Using the intelligent processing and publishing features, data can be polled, logged, or even automatically pushed when I/O statuses change. Also, data can be pushed to connect and interact with a public or private cloud servers.

The IO5202 Series has been designed for demanding industrial applications. Supporting a wide operating temperature range of -40ºC~70ºC and Industrial EMC protection, the IO5202 Series can perform under a variety of environmental conditions, such as power input voltage, shock, drop and vibration.
