Ethernet I/O Module/Modbus TCP/MQTT/8AI
The ET-2217CI is a channel-to-channel isolated analog input module that includes 8 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 50mA overcurrent protection
at 110 VDC/VAC. Voltage and current input is software configurable.
The sampling rate of the ET-2217CI 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 ~ 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. The ET-2217CI-4 has the
same specifications as ET-2217CI, but provides 4-channel analog inputs.
