Description

0745648E ABB 0745745Q Control card system integration controllable module

The scope of this electrical installation handbook is to provide the designer and user of electrical plants with a quick reference, immediate-use working tool. This is not intended to be a theoretical document, nor a technical catalogue, but, in addition to the latter, aims to be of help in the correct definition of equipment,
in numerous practical installation situations.The dimensioning of an electrical plant requires knowledge of different factors relating to, for example, installation utilities, the electrical conductors and other components; this knowledge leads the design engineer to consult numerous documents and technical catalogues. This electrical installation handbook, however, aims to supply, in a single document, tables for the quick definition of the main parameters of the components of an electrical plant and for the selection of the protection devices for a wide range of installations. Some application examples are included to aid comprehension of the selection tables.Electrical installation handbook users The electrical installation handbook is a tool which is suitable for all those who are interested in electrical plants: useful for installers and maintenance technicians through brief yet important electrotechnical references, and for sales engineers through quick reference selection tables.Validity of the electrical installation handbook Some tables show approximate values due to the generalization of the selection process, for example those regarding the constructional characteristics of electrical machinery. In every case, where possible, correction factors are given for actual conditions which may differ from the assumed ones. The tables are always drawn up conservatively, in favour of safety; for more accurate calculations, the use of DOCWin software is recommended for the dimensioning of electrical installations.

0745648E ABB 0745745Q is a distributed and modular I/O system that communicates with controllers over PROFIBUS-DP/DPV1 or direct (via Modulebus).The S800 I/O system is DIN rail mounted and consists of Fieldbus Communication Interfaces, Modulebus Modems, S800 I/O modules and Module Termination Units
(MTU). S800 I/O modules (not S800L) are mounted on MTU’s, this makes them hot-swappable. Depended on the mounting requirement (horizontal or vertical) and on the field termination needs (powering, fusing etc.) there are numerous of MTU’s to choose from.The S800 I/O system supports fully redundant applications, redundancy can be built in on both communication level and I/O module level.

The metal sheet shall at least be 2.5 mm thick and at least 180 mm high with preferably one side bend 90 degrees to increase the stability. The metal sheet shall be mechanically fastened at least every 500 mm to the cabinet or rack with a minimum of four screws. The fastening to the cabinet frame shall be performed with
self-tapping screws to get a good grounding connection.DIN-rail type with height 7.5 mm shall be used. Refer to type NS 35/7.5 according to standard EN50022.

The S800 I/O is mounted on a standard DIN-rail according to EN 50022 NS35/7,5.The DIN-rail is mounted in a cabinet or on an enclosure wall to a metal sheet with fastening screws every 100 mm to ensure a good chassis ground connection in the cabinet or an open rack. The ModuleBus master, ModuleBus Modem, MTUs and S800L I/O modules are mounted to the DIN rail. In environments with major vibrations, the MTUs shall also be screwed on the metal sheet. The FCI, ModuleBus Modem and MTUs have a snap locking device that attaches it to the mounting rail.It is possible to mount the FCI, ModuleBus Modem, MTUs and S800L I/O modules both vertically and horizontally.To mount the FCI, ModuleBus Modem or MTU, place it on the top edge of the DIN rail, release the rail latch with a flat blade screw driver and snap the bottom mechanism into place. When the unit is in place on the DIN rail and in position, take away the screw driver and the rail latch will fix the unit in position on the DIN rail.Release the unit from the DIN rail in a similar way.
