Product Type: Managed Industrial Ethernet Switch Product Model: 6GK5308-2FL00-2AA3 Port Configuration: 2 x1000Mbps Single-mode Fiber Interface, 1x10/100/1000Mbps Electrical Port, 7x10/100Mbps Electrical Port Network Standard: PROFINETIO Device, EtherNet/IP Compatible Power Supply: Redundant Power Supply Operating Temperature Range: -40 ° C to + 70 ° C Weight: 1.493 kg Certification Standard: IEC62443-4-2 Certified The SIEMENS Managed Industrial Ethernet Switch (Model 6GK5308-2FL00-2AA3) is a high-performance networking device. Designed for industrial automation and control systems.It has eight Ethernet ports, including two 1000Mbps single-mode fiber ports, one 10/100/1000Mbps electrical port and seven 10/100Mbps electrical ports, which can meet the data transmission needs in different scenarios. The switch supports various network management protocols, such as VLAN, RSTP and SNMP, which can effectively improve the stability and security of the network. In addition, the switch has a redundant power input function, which can automatically switch to the standby power supply in case of power failure to ensure the continuous operation of the equipment.The wide operating temperature range from -40 ° C to + 70 ° C makes it suitable for harsh industrial environments. The installation methods are flexible and diverse, and DIN rail installation, S7 mounting bracket or wall mounting can be selected, which is convenient for users to install according to actual needs.

The Yokogawa AAI143-H50/K4A00 is a flange-mounted absolute pressure transmitter from the DPharp EJA-E Series. It is designed for high-accuracy absolute pressure measurement in demanding industrial applications such as vacuum systems, distillation columns, and high-pressure processes. The transmitter features Yokogawa's single-crystal silicon resonant sensor technology, ensuring exceptional long-term stability and reliability. The model suffix /K4A00 indicates specific configuration options, typically including Hastelloy C276 diaphragm material and standard calibration, ensuring compatibility with corrosive process media.
