iP-8411-MRTU-G CR: Module CPU 4 cổng COM Modbus ASCII/RTU +  4 khe cắm module mở rộng


• Supports Modbus RTU/ASCII Slave
• Auto Configuration
• LED Indicators for Fault Detection
• 4 I/O Slots for I-8K and I-87K Series Modules 
• Operating Temperature: -25 ~ +75 °C


iP-8411-MRTU series is a Modbus serial I/O expansion unit to expand I-8K and I-87K series I/O modules over the serial port for industrial monitoring and controlling applications. There are more than 50 I/O modules supported with the unit, including analog input/output, digital input/output, counter, frequency I/O modules. It is designed to be used in harsh and noisy environment, so the hardware is manufactured with wide power input range (10 ~ 30 VDC), isolated power input and can operate under wide temperature (-25 ~ +75 °C). To simplify installation and maintenance of I/O modules, it provides many useful features, such as: auto configuration, LED indicators for fault detection, dual watchdog to keep alive, programmable power on and safe values for safety.

Modbus is a very wide known protocol in the industrial manufacturing and environment monitoring fields. Many SCADA software, HMI and PLC has builtin driver to support Modbus devices. Besides, we also provide SDK on different platforms, such as Windows XP, Window CE 5.0/6.0, Linux, MiniOS7. Therefore, it is very easy to integrate remote I/O to customer’s applications.
