MTL8000 2/1 Modules

 

  • All I/O modules are connected to a high speed Bus Interface Module (BIM) via a proprietary bus system called "Railbus" and one BIM can control up to 32 modules. The module carrier provides the transmission medium for the Railbus and by plugging a module onto a carrier, connections are made between the module and the bus. The connectors on the carrier also provide the power supply links to the module. Additionally, 2/1 modules can use intrinsically safe wiring to send and receive signals into hazardous areas.

MTL8000 Module Carriers and Cables

 

  • Carriers are the building blocks on which the MTL8000 system is assembled. They distribute the basic power supply services to the modules, and provide the communications route between the Bus Interface Module (BIM) or Controller and the I/O modules. Most carriers can be mounted on DIN rail or directly to a flat surface and may be joined end-to-end to extend the size of an installation. Multipin connectors at the end of each carrier carry the system power supply and internal 'Railbus' communications across to the next carrier. All I/O module carriers have their own independent grounding busbar, with screw terminals, to terminate the screens/shields of field-wiring cables. At each end of the bar there is a separate terminal to enable it to be linked to other carriers, or to the system ground, as required.

MTL8000 2/x Power Supplies

 

  • Good power supply management is at the heart of the MTL8000 system.
    AC and DC power supply units are available to suit the available resources.
    All units are designed to endure the harsh environmental conditions that are frequently found in process plants and, naturally, they meet rigorous EMC and electrical safety standards.
    Power supply connections are minimised and simplified to ensure that power provision requires the minimum of wiring effort
    8000 series power supplies are designed to support redundancy when required. Most have “health” signal outputs for early warning of problems.

railbus

MTL8000 Railbus Isolator

 

  • The Railbus Isolator module provides galvanic isolation between the 2/2 and 2/1 sections of the Railbus, thus preventing fault voltages on the general purpose (2/2) section of the Railbus from invading the parts that have IS field wiring. A Railbus Isolator is required only in nodes that contain IS field wiring. The Railbus Isolator mounts on its own carrier and is placed in the line of carriers immediately before the first (2/1) carrier that will carry IS field wiring. It is usually followed by an 8920-PS-DC IS module power supply (on its own carrier) which provides power for the 2/1 I/O modules.

bim

Bus Interface Modules (BIM’s)

 

  • An MTL8000 node uses a Bus Interface Module (BIM) to communicate with the host controller via a local area network (LAN). Different BIMs can be chosen to operate with a range of popular fieldbus protocols. The BIM mounts on a carrier and receives all of its communication and power links from it. The BIM uses the RS485 communications standard. Other alternatives are RS422, by changing switches (where available) on the carrier, or RS232 by fitting an in-line converter. Switch options sometimes offer alternative methods for terminating the LAN. Some BIMs also have a second LAN connection to maintain communications in the event of damage occurring to the main communications link.
