The fully modular connection for connecting to the digital I/O modules of the SIMATIC S7-1500 or ET 200MP (35 mm design) consists of modified front connectors, called front connector modules, pre-assembled connecting cables of various lengths, and terminal modules. Suitable components can be selected for the application in question and joined by means of simple plug-in connections. The terminal modules are used instead of conventional terminal blocks and act as the interface to the sensors and actuators.
Modified front connectors, called front connector modules, are available for connecting to the I/O modules (35 mm design). These are plugged into the I/O module to be wired instead of the front connector. The front connector modules are available in many different versions for digital I/O modules, analog I/O modules and for the 24 V, 2-ampère module. The connecting cables are plugged into these front connector modules.
The connecting cable is available in two different versions.
As a pre-assembled 16-pole or 50-pole round cable (shielded or unshielded) up to a length of 10 m, or as a 16-pole round-sheath ribbon cable (with or without shield), which can be easily assembled by the user; or as 2 x 16-pole round-sheath ribbon cables (without shield).
When assembled, there are one or two insulation displacement connectors (female ribbon connectors) at both ends of the cable.
The round-sheath ribbon cable is assembled by the user with the aid of pliers (can be ordered separately). The cable transmits 8 or 2 x 8 channels over a distance of up to 30 m.
The connecting cable connects the front connector module with the terminal module.
The system has digital and analog terminal modules for connecting the I/O signals. These are snapped onto the standard mounting rail. The terminal modules with basic or signal functionality are available in 1-byte or 4-byte versions.
Terminal modules are available for two different connection methods: with push-in or screw-type terminals The potential can be fed in at the terminal module or at the front connector module.
If other voltage or power levels are required in the field, the terminal module for TPRo or TPOo output signals is used. For the TPRo terminal module, relays are used for the implementation. For the TPOo terminal module, optocouplers are used for the implementation. This converts the 24 V DC output signal simply and reliably to another voltage or power level. If 230 V AC or 110 V AC input signals have to be transmitted to the controller in the field, a connection module with relay TPRi is available that simply converts the 230/110 V AC signal to 24 V DC. This means that there is always the same voltage level on the module side.
Use with optocouplers for the TPRo relay modules
If higher switching frequencies of the relay terminal module are required for the output signals, the relay can simply be replaced with an optocoupler (note technical specifications) in order to increase the switching frequency here.

輸電集團的業(yè)務(wù)范圍包括高壓輸電解決方案、高壓開關(guān)產(chǎn)品和系統(tǒng)，以及創(chuàng)新的直流和交流輸電系統(tǒng)。交鑰匙變電站和電力變壓器進一步完善了輸電集團的產(chǎn)品組合。通過我們運營良好的本地化生產(chǎn)基地，輸電集團一直致力于將創(chuàng)新型的技術(shù)引入中國市場。
2011 年春，西門子能源獲得訂單，為位于中國南部的兩個高壓直流輸電工程（糯扎渡—廣東特高壓直流輸電工程和溪洛渡—廣東高壓直流輸電工程）提供關(guān)鍵部件。項目業(yè)主方為中國南方電網(wǎng)公司。糯扎渡—廣東高壓直流輸電工程的輸電電壓為±800千伏，輸電容量達 5000 兆瓦。溪洛渡—廣東高壓直流輸電工程的輸電電壓為±500 千伏，輸電容量為 6400 兆瓦。兩個工程建成后將為廣東地區(qū)的大城市提供電力。這兩個系統(tǒng)計劃于 2013 年投入運行。
2012 年，西門子為大連供電公司交付定制化的高度集成的、技術(shù)領(lǐng)先的智能車載移動變電站設(shè)備，開創(chuàng)了國內(nèi)同類產(chǎn)品的先河。該先進的智能化移動變電站完全按照中國電網(wǎng)現(xiàn)狀和道路狀況設(shè)計，具有靈活組合、便于運輸、安裝快捷、施工周期短等特點。此外，由于其集成化程度高，該移動變電站占地面積也較小。
