Ethernet I/O Module with 8-channels AO



Model: ET-7028/PET-7028	Model: ET-7228/PET-7228


Built-in Web Server Web HMI Support for both Modbus TCP and Modbus UDP Protocols Communication Security Dual Watchdog Wide Operating Temperature Range: -25 ~ +75°C I/O Pair Connection Built-in I/O AO: 8 Channels

The ET-7028/PET-7028/ET-7228/PET-7228 is a multifunction module with 8 channels analog output. 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-7028/PET-7028 is fully RoHS compliant and provides 4 kV ESD protection as well as 2500 VDC intra-module isolation.
