ET-7228 CR
Ethernet I/O Module with 2-port Ethernet Switch and 8-ch Analog output
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.
