Introduction

The ET-7028 is aN 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 the corresponding jumper. The ET-7028 is fully RoHS compliant and provides 4 kV ESD protection as well as 2500 VDC intra-module isolation.

Application

Building Automation, Factory Automation, Machine Automation, Remote Maintenance, Remote Diagnosis, and Testing Equipment.
