The ET-2217H / PET-2217H is a high-speed analog input module featuring 8 differential channels. Each analog input channel can be individually configured to one of several input ranges: ±2.5 V, 0–5 V, ±5 V, 0–10 V, ±10 V, 0–20 mA, 4–20 mA, and ±20 mA. The input type —voltage or current—can be selected via a DIP switch. The module also provides  overvoltage protection up to 50 VDC, and overcurrent protection of 50mA at 50 VDC/VAC.
 
With a sampling rate of 8 KHz (total for all channels), the ET-2217H / PET-2217H supports TCP streaming for continuous data transmission of voltage and current values. Additionally, it features EMS protection (EFT/ESD/Surge) and 3000 VDC I/O isolation, ensuring reliable operation in harsh industrial environments.
