Description
1.3 What is the ET 200S distributed I/O system?
Communication-capable, system-integrated
motor starters: Direct and reversing starter up to
7.5 kW
Permanent wiring due to the separation of
mechanical and electronic components
Individual connection of power modules to
common potential
Robust structure for rough industrial conditions (5
g vibration resistance)
Integrated voltage buses
Power bus up to 50 A for motor starters
Screw-type terminals, spring-loaded terminals,
and Fast Connect
•
•
Fast Connect
Replaceable terminal box in the terminal module
Automatic coding of the I/O modules
Large label plate
High data transmission speed of up to 12 Mbps
on PROFIBUS DP and 100 Mbps on
PROFINET IO
Integrated safety functions
For motor starters up to safety category
4 according to EN 954-1
Fail-safe modules
1-10
Characteristics
2- and 3-conductor connection or
2-, 3- and 4-conductor connection
PLC inputs and outputs, terminal blocks, circuit
breakers and contactors in a plug-in module save
space and the effort involved in wiring
Prewiring possible
•
Module replacement during operation of the
•
ET 200S ("hot swapping")
Individual formation of voltage groups
•
(identifiable by color coding of the TM-P
terminal modules for power modules)
Simple load interruption
•
High operating reliability when mounted directly
on the machine, high availability
Connection system
Reduced effort required for wiring
Minimization of wiring in 400 V range
A change in terminal connection method is not
necessary
Optimal selection in terms of space and cost
Connection method with no stripping required
•
Time saving during wiring
•
No need to remove the terminal module in the
event of terminal damage
Quick and reliable module replacement
Adequate space for clear labeling
Short response times
Savings on time-consuming safety engineering
For detecting and outputting fail-safe signals via
PROFIBUS (PROFIsafe) up to Safety Category 4
(EN 954-1)
