Product Overview
1-9
Distributed I/O System ET 200S
EWA 4NEB 780 6024-02 07
Table 1-2 Features and Benefits of the ET 200S
Features Benefits
Permanent wiring due to the separation of
mechanical and electronic
components
Prewiring possible
Module replacement during operation of
the ET 200S (“hot swapping”)
Individual connection of power modules to
common potential
Individual formation of potential groups
(identifiable by color coding of the TM-P
terminal modules for power modules)
Simple load interruption
Robust structure for rough industrial
conditions (5 g vibration resistance)
High operating reliability when mounted
directly on the machine, high availability
Connection System
Integrated voltage buses Reduced effort required for wiring
Power bus up to 50 A for motor starters Minimization of wiring in 400 V range
Screw-type terminals, spring terminals and
Fast Connect
A change in terminal connection method is
not necessary
2- and 3-wire connection, or
2-, 3-, and 4-wire connection
Optimal selection on grounds of space and
cost
Fast Connect Connection method with no stripping
required
Saves time with wiring
Terminal box in terminal module replaceable No need to remove the terminal module in
the event of terminal damage
Automatic coding of the I/O modules Quick and reliable module replacement
Large label plate Adequate space for clear identification
High data transfer rate of up to 12 Mbps; Short response times of PROFIBUS and
backplane bus
Integrated safety functions
With motor starters up to safety category
4 in accordance with EN 954-1
Saves spending money on costly safety
equipment
Fail-safe modules To detect and output fail-safe signals via
PROFIBUS (PROFIsafe) up to safety
category 4 (EN 954-1)
DP master
All the ET 200S modules can communicate with all DP masters that comply with
IEC 61784-1:2002 Ed1 CP 3/1. All functions can be used with the standard master.
