MTL8000 2/xMTL8000 2/x

MTL8000 is a completely modular I/O solution for both general purpose and hazardous area applications. Based upon a carrier system that supports a range of modules, it offers a wide variety of I/O functions, including AC mains and intrinsic safety signals - even within the same node.

It has an "open" architecture that allows communication with a variety of different field-buses by selecting the appropriate type of Bus Interface Module (BIM).

I/O Modules
I/O modules transfer signals to and from field instruments. Input modules receive signals from transmitters and sensors and convert them into a digital form for presentation to the BIM. Output modules receive commands from the BIM and transfer them to actuators. A wide range of modules is available, including types for low-level instrumentation, AC mains and intrinsically safe signals. I/O modules typically have 4, 8 or 16 field channels.

Field terminals
Field terminals provide the interface between the I/O modules and the field wiring. They include fusing and loop-disconnect as options. A mechanical keying system prevents an I/O module from being connected to the wrong type of field terminal. Field terminals mount onto the module carrier, one to each I/O module. They are clamped firmly by the I/O module to form an electrical and mechanical assembly of high integrity. They may be replaced in service without removing carriers or disturbing the operation of other modules.

Carriers
Carriers form the MTL8000 physical and electrical backbone by providing a mounting onto a flat panel or T- or G-section DIN rail. They support and interconnect the BIM, power supplies, I/O modules and field terminals, and carry the address, data and power lines of the internal Railbus. They provide a termination points for the LAN and field wiring cable screens and can also distribute bussed field power to the I/O modules. I/O module carriers are available to support four or eight I/O modules.

Power supplies
Good power management lies at the heart of a true distributed I/O system. MTL8000 power supplies accept locally available unregulated power and provide a regulated supply for the BIM and I/O modules. Supply redundancy is supported.

Bus Interface Module (BIM)
The BIM provides a serial data connection to a host controller, which could be a distributed control system (DCS), a programmable logic controller (PLC), or a PC running a soft control package. A choice of BIMs allows you to accommodate the most popular fieldbus protocols. The BIM also uses a fast internal bus to pass data to, and obtain data from, the I/O modules.
