S800 I/O is a comprehensive, distributed and modular process I/O system that communicates with parent controllers and PLCs over industry-standard field buses. The TB840 ModuleBus Modem is a fiber optic interface to the Optical ModuleBus. TB840A is used in redundancy configurations where each module is connected to different optical ModuleBus lines, but connected to the same electrical ModuleBus.

The ModuleBus Modem has an electrical and an optical Modulebus interface which are logically the same bus. A maximum of 12 I/O modules can be connected to the electrical ModuleBus and up to seven clusters can be connected to the fiber optic ModuleBus. The fiber optic interface is intended for local distribution of I/O clusters and where more than 12 I/O modules are required in an I/O station.

Input power fusedThe MVME5500 is the latest flagship of the Motorola VME product line, enabling even higher levels of performance in a single VMEbus slot. The MVME5500 utilizes the latest MPC7455 processor running at speeds of 1 GHz and beyond, which is ideal for data intensive applications. The MVME5500 provides more than just faster processor performance; it provides balanced performance from the processor, memory, local buses, and I/O subsystems. The powerful Marvell Discovery system controller, with support for a 133 MHz host bus and a 133 MHz SDRAM memory bus, is well matched to the high-speed processor. To match the system I/O to the outstanding processor performance, the MVME5500 provides dual 64-bit, 33/66 MHz PCI buses. Each PCI bus has a PMC site supporting cards running at 33 or 66 MHz. The Universe II VME interface and PMCspan connector are isolated from the PMC sites on a dedicated 33 MHz PCI bus segment, so that both PMC sites are capable of 66 MHz operation.

The MVME5500 also offers a Gigabit Ethernet interface, a 10/100BaseTX Ethernet interface, and two serial ports. All of this adds up to a set of well-balanced, high-performance subsystems for unparalleled performance. The MVME5500 series is designed to meet the needs of OEMs servicing the defense and aerospace, industrial automation, and medical imaging market segments. Customers looking for a “technology refresh” for their application while maintaining backward compatibility with their existing VMEbus infrastructure can upgrade to the MVME5500 series and take advantage of the enhanced performance features.

 

SPECIFICATIONSPart No.: IS420ESWBH3AManufacturer: General ElectricCountry of Manufacture: United States(USA)Product Type: IONET Switch, 16 PortSeries: Mark VIeIS420ESWBH3A is an Ethernet IONet Switch and is part of the GE Speedtronic Mark VIe gas turbine control system. It is available in 8 ports, 10/100BASE-TX. The ESWB Ethernet 10/100 switches are specially designed to meet the needs of real-time industrial control solutions and are required for all IONet switches used in Mark VIe & VIeS safety control systems. It is a DIN – Rail mounting module. To meet the requirements for speed and functionality the following features are provided.

IS420ESWBH3A InstallationInstall the switch using a DIN-rail on the control system panel for new installations. Connect the copper and/or fiber wires according to the system’s redundancy and requirements. Connect the switch to the 28 V dc electricity from the power distribution board.

IS420ESWBH3A ConfigurationMultiple insertions and removals are supported using RJ-45 connectors, which have a service life expectancy of 200 insertion/removal cycles. Torsion pressures are applied to connection components along any axis, as well as static tension forces caused by cable weight and cable dressing.

MountingThe switch enclosure can be DIN-rail mounted or panel mounted (switch mounts to back wall of panel with bracket). The DIN-rail mounting system complies with vibration and shock requirements. Both mounting types allow for easy access to user connections.

OperationA level 1 Ethernet switch’s performance is mostly determined by its ability to buffer packets. When a level 1 switch receives a continuous stream of broadcast or multicast packets, it must send those packets out after they have been fully received. A single incoming stream should take up enough memory to buffer one packet, or at the very least one packet per port.

Switch ReplacementWhen the ESWA or ESWB is used to replace an unmanaged switch, the existing mounting brackets, which can be panel or DIN rail mounts, are used.
