Compact MQTT IO module with four channel-to-channel isolated analog inputs

The ICP DAS ET-2217CI-4 offers a channel-to-channel isolated analog input module. This module has 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, with high over-voltage protection of 120 VDC and 50mA overcurrent protection at 110 VDC/VAC, the voltage and current input is software configurable.

The ET-2217CI-4 has an adjustable sampling rate, with options for fast (200Hz) or normal(10Hz) mode. This Ethernet IO module can record voltage and current information, along with the date and time stamps. The ET-2217CI-4 module supports industrial protocols including Modbus TCP, and MQTT- an emerging machine-to-machine (M2M)IoT (Internet of Things) connectivity protocol.

Additionally, the ET-2217CI-4  IO 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.

Key features:

  • Record voltage and current measurements with date and time stamps
  • Max. recording for each channel: 480,000
  • 4-channel analog inputs with 3000 VDC channel-to-channel isolation
  • Built-in web server and I/O pair connection (push and pull)
