TNM4000-T Series Industrial Switches

basic information

TNM4000 Industrial Transportation Industry Switches are specially designed for transportation industry.TNM4000 Industrial Transportation Industry Switch provides multiple slots and various integrated forms,including gigabit network,content exchange and PRP/HSR module,all the modules support online upgrade.All models of TNM4000 Industrial Transportation Industry Switches are equipped with unified optical modules and operating system software,forming a system that can adapt to future development.Due to the operating consistency,the utilization is greatly improved as well.With hardware-based algorithm, MRD-Ring®(MRDcom Real-Time Ring)technology ensures less than 5ms self-recovery time of every node and less than 50ms self-recovery time of the network.TNM4000 Industrial Transportation Industry Switch also supports MRD-Ring® Media Redundancy Protocol(compliant with IEC62439)and PRP/HSR(compliant with IEC62439-3).TNM4000 Industrial Transportation Industry Switch utilize FPGA and CPLD dynamic reconfiguration and replicate programming technology for high stability and reliability,various key operating parameters can be monitored locally and remotely.Advanced solution, extended industrial design,and patented technologies make TNM4000 Industrial Transportation Industry Switch one of the top choices for harsh industrial environments.
