Introduction

The ET-7052 provides 8 wet contact digital input channels and 8 source-type digital output channels. It features optical isolation for 2500 VDC of transient overvoltage protection but doesn't provide channel-to-channel isolation. Each input channel can be used as a 32-bit counter and each output channel can drive a 650 mA load. The power-on value and safe value of the digital output channel are programmable. It can safely be used in applications where hazardous voltages are present.

Application

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