S400 Remote I/O for Advant Master DCS

Migration and support for ABB S400 remote I/O for Advant Master DCS, and the Advant Controller 410 and Advant Controller 450.

S400 Remote I/O Units makes it possible to distribute the system’s inputs and outputs to distances of up to 750 m from the Process Station. The Process Station and the various I/O units communicate via the ABB MasterFieldbus serial bus

The laying of cable represents a major part of the costs involved in such a system. For this reason it is obviously advantageous to be able to transmit a large number of signals serially between the Process Station and one I/O unit and to have separate signal wires only between the I/O unit and the process. The more spread out the process, the greater the advantages offered by Distributed I/O.

S400 I/O for Advant Master Life cycle status
S400 I/O moved into the Classic life cycle phase in 1999, to Limited in 2005 and finally to the Obsolete phase in 2015.
ABB strongly recommends customers to evolve S400 remote I/O to S800 I/O by the use of S800 I/O evolution kits, enabling a quick and easy replacement.

Overview
Application

All of the I/O units have the same mechanical design and differ only with regard to their indicators and with regard to the type, number and grouping of their inputs and outputs.

Each unit is housed in a cast aluminium chassis. The circuit board is screwed permanently to the chassis and uses it as a heat sink.

The chassis and the electronics are covered by a plastic cover which may be removed only by a qualified service technician. Above the cover there is a lid which covers the accessible parts of the electronics, including the address switches.All of the inputs and outputs have two-wire connectors and require no additional terminal units.
