ET-7028
Remote Ethernet I/O Module with 8-channel Analog Output. Supports AO types of +0 VDC ~ +5 VDC, +/-5 VDC, +0 VDC ~ +10 VDC, +/-10 VDC +0 mA ~ +20 mA, +4 mA ~ +20 mA (Jumper Selectable). Communicable over Modbus TCP and UDP. Supports operating temperatures between -25°C ~ 75°C (-13°F ~ 167°F) and has a din rail mount.
Features
The ET-7028 is a multifunctional module with 8-channel 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.
