Murrelektronik MVK-MPNIO F DI8/4 F DO4 Part number Murr 55563 Murr bus module distribution

Murr 55563 bus module is a shared data transmission device. Although multiple devices can be connected to the bus, typically only one pair of devices participates in data transmission at any given time. According to the form of information transmission, buses can be divided into parallel buses and serial buses. A parallel bus transmits n-bit binary information simultaneously using n transmission lines. Its characteristics include fast transmission speed, but the system structure is more complex; it is used for connections between various components within a computer system. A serial bus shares a single transmission line for multi-bit binary information, with the multi-bit binary information passing through the bus in chronological order.
