Features

applicationImage-ET-7228The ET-7228 is a multifunctional module with 8 channels of analog output and 2 Ethernet ports for daisy chain connection. It provides a variety of programmable analog output options (+/-5 V, +/-10 V, 0 ~ 20 mA and 4 ~ 20 mA), and each analog output can be programmed to accept either current or voltage as output depending upon the position of corresponding jumper. The ET-7228 is fully RoHS compliant and provides 4 kV ESD protection as well as 2500 VDC intra-module isolation. Supporting Modbus TCP, it is easy to integrate with your SCADA system as well.

  • 2 Ethernet Ports for Daisy Chain Network. Saves Cabling Cost.
  • Built-in Web Server For Easy Configuration
