TRICONEX 3511 8312 Uses ESD safety control system Invensys Industrial card module

TRICONEX 3511 8312 Application ESD Safety Control System Invensys Industrial Card Module Communication (PLC) allows data communication over wires that are also used for power transmission. PLCS work by adding a modulated carrier signal that is formed by superimposing a data signal on top of a low-frequency power signal. The transmission frequency of the electrical signal is 50-60 Hz, and the transmission frequency of the data signal is MHz. PLCS are also known as power line carriers, Power Line Digital Subscriber Lines (PDSL), or power line networks (PLN). Narrowband PLCS: They operate at the lower frequencies of 3-500KHz. They have a low data rate, but a high range of several kilometers. They’re for smart grids. Broadband PLCS: They operate at high frequencies of 2-250mhz and have high data rates of more than 100Mbps. They are used for short ranges. They are used in home automation. Home Network (LAN) : Existing wires in the home can be used for LAN connections within the home, eliminating the need to set up network cables. The communication device should have an Ethernet port. Establish an Ethernet connection by plugging a power cord adapter into a power outlet. Power Line broadband (BPL) : It transmits bidirectional signals between transformers via AC medium voltage distribution lines and between transformers and customer outlets via AC low voltage lines. In-vehicle network communication: Digital signals are transmitted through DC battery lines in the vehicle. Universal Mobile Telecommunications System (UMTS) is a broadband, packet-based 3G mobile cellular system based on the GSM standard. The UMTS specification covers the entire network system, including radio access network, core network and user authentication. UMTS is a component of the International Telecommunication Union’s (ITU) IMT-2000 standard developed by 3GPP. It uses a wideband Code Division Multiple Access (W-CDMA) air interface. It provides the transmission of text, digital voice, video and multimedia. It provides high bandwidth for mobile operators. It offers a high data rate of 2Mbps. For High Speed Downlink Packet Access (HSDPA) phones, the data speed in the downlink connection is up to 7.2Mbps. It is also known as Freedom of Mobile Multimedia Access (FOMA). It contains the specifications for the entire mobile network system – the core network (mobile application part) of UTRAN’s Radio Access Network (UMTS Land Radio Access Network) MAP authenticates users via SIM (User Identification Module) cards.
