Communication protocols and interfaces: 4351B supports multiple communication protocols, including Modbus, DNP3, OPC, Ethernet/IP, TCP/IP, RS-232/485, CAN bus, etc., to meet the communication needs of different industrial environments.
Communication interface: 4351B is usually equipped with Ethernet (RJ45 port), serial port (RS-232/485), etc., and some models support multi-channel communication.
Transmission speed: up to 10 Mbps, some models support high-speed data transmission.
Redundancy design and safety performance: Three module redundancy (TMR) architecture is adopted to ensure that the system can still operate normally in case of a single point of failure, and improve the availability and fault tolerance of the system.
Equipped with data encryption and authentication functions to ensure data confidentiality and system security during communication.
Processor and memory configuration: Some models are equipped with a 32-bit processor, running at a frequency of 33MHz, with 1MB RAM and 4MB Flash. Some models support higher capacity memory (such as 512MB RAM and 2GB Flash).
Function and Application: As an important component of Triconex Safety Instrumented System (SIS), 4351B is mainly used to achieve data transmission and communication between the system and other devices or systems. Widely used in industries such as oil and gas, chemical, power, nuclear energy, metallurgy, pharmaceuticals, food and beverage, for key safety control scenarios such as fire alarm, gas leak detection, emergency parking systems, equipment protection systems, environmental monitoring systems, etc.
