Module 16 kênh đầu vào số kết nối 2 cổng Ethernet Modbus TCP/IP ICP DAS ET-7251

Features

  • Built-in Web Server

  • Web HMI

  • Support for both Modbus TCP and Modbus UDP Protocols

  • Communication Security

  • 2-port Ethernet Switch for Daisy-Chain Topology

  • Dual Watchdog

  • Wide Operating Temperature Range: -25 ~ +75°C

Introduction

The ET-7051/PET-7051/ET-7251/PET-7251 provides 16 wet contact digital input channels. Each input channel can be used as a 32-bit counter. It features optical isolation for 3750 Vrms of transient overvoltage protection but doesn’t provide channel-to-channel isolation. It can safely be used in applications where hazardous voltages are present.
