ET-2217CI-4 is a 4-channel analog input module with channel-to-channel isolation. All analog input channels can be individually configured with input ranges including ±1 V, ±2.5 V, ±5 V, ±10 V, 0 ~ 20 mA, 4 ~ 20 mA, and ±20 mA. The module can be set as voltage or current inputs via the software and provides up to 120 VDC overvoltage protection, as well as 50 mA overcurrent protection at 110 VDC/VAC. Additionally, each 4 ~ 20 mA input channel features open wire detection.

The sampling rate of ET-2217CI-4 can be set to either fast mode (200 Hz) or normal mode (10 Hz) for recording voltage and current values with timestamps. The module supports commonly used industrial protocols such as Modbus TCP and the emerging M2M (Machine-to-Machine) or IoT (Internet of Things) connectivity protocols like MQTT. It also provides EMS (EFT/ESD/Surge) protection and 3000 VDC I/O isolation to enhance noise protection capabilities in industrial environments.
