There are five types of fuses from Siemens, which can be selected according to your own practical needs: 1. Piercing fuse: It is often used at the end of the line of 380V and below voltage level, as a short-circuit maintenance application for distribution branch lines or electrical equipment. ...

1. Can the digital input of the same module be connected to NPN and PNP signals at the same time? No, because the two types of signals NPN and PNP are in the opposite direction of the current at the DI point in the loop formed by the DI terminal, and similarly the current direction at the M point is also opposite, as shown in Figure 7 and Fig.

At the 2021 "Together, Together, Together" award ceremony hosted by the Germany Chamber of Commerce in China, Siemens once again won praise for "leading the way to building a sustainable supply chain". Siemens has previously pledged to reduce emissions in its global supply chain by 20% by 2030 and by 2050 to achieve ...

1 Check whether there is EMC interference in the inverter or network cable To ensure that the inverter is firmly grounded, the grounding resistance of the inverter is generally required to be less than 4 ohms. Industrial-grade shielded network cables and network cable connectors are used The shielding layer of the network cable should be firmly grounded, and the shielding of the more ambitious ...

Siemens today signed a strategic collaboration agreement with Shenzhen Liye Group Co., Ltd. (Liye Group). The two ends will take the construction of Liye Group's new lithium battery industrial park as the key, and further deepen the in-depth cooperation between the two ends in the fields of digitalization, low-carbonization, and digital talent training.

After the 3RW series soft starter is started, there are two main operation methods: continuous operation and bypass operation. At this time, the thyristor is in a fully conductive state, and the system enters a constant speed operation state. Here, we advocate that the user should choose the bypass method to operate, that is, when the starting is completed to reach the full voltage ...
