The ET-2217CI-4 is a channel-to-channel isolated analog input module that includes 4 analog input channels. The module provides a programmable input range on all Analog Input channels (±1 V, ±2.5 V, ±5 V, ±10 V, 0 to 20mA, 4 to 20mA, and ±20 mA). Each analog input channel can be configured for an individual input range, providing a high overvoltage protection of 120 VDC and 50 mA overcurrent protection at 110 VDC/VAC. Voltage and current input is software configurable. 

The sampling rate of the ET-2217CI-4 is adjustable and can be set to either fast (200Hz) or normal (10Hz) mode. It can be used to record voltage and current information, including the date and time stamps. Support is provided for common industrial protocols such as Modbus TCP, as well as the emerging machine-to-machine (M2M)/)IoT (Internet of Things) connectivity protocol – MQTT. The module also features per-channel open wire detection for 4 to 20 mA input and provides 4 kV ESD/EFT protection, 2 kV Surge protection, and 3000 VDC intra-module isolation and channel-to-channel isolation.

LogReader is a simple tool that can be used to read the log data of the module and then export it to a CSV file. The user can download it from the Download Center.
