ADAM-6251 15-ch Isolated Digital Input Modbus TCP Module

Download the ADAM-6251 data sheet.

Overview

The ADAM-6251 features 16 Isolated Digital Input channels. The daisy-chained Ethernet ports simplify the wiring for multiple modules and eliminates the need for a dedicated port for each module.

Features

• Daisy chain connection with auto-bypass protection
• Remote monitoring and control with smart phone/tablet
• Group configuration capability for multiple module setup.
• DI/O LED Indication
• Flexible user-defined Modbus address
• Intelligent control ability by Peer-to-peer and GCL function.
• Multiple protocol support: Modbus TCP, TCP/IP, UDP, HTTP, DHCP, RESTful, SNMP and MQTT
• Web language support: XML, HTML 5 and Java Script
• System configuration backup
• User Access Control
• Easy mounting on DIN-rail, panel or piggyback
