Features and benefits
Properties
Image
Structure
● Station design optimized to contain costs
● Reduced configuration and documentation
effort
● Space savings due to the ability to string
modules together in any order
Broad area of application
● Prewiring possible
● Hot swapping of modules while the ET 200iSP
is operating when at least two electronic
modules are present.
Reduced effort required for wiring
Connection system
Use of most suitable terminating technique
Intrinsically safe sensors, actuators and HART
field devices up to Zone 0/ 20 can be connected
Quick and reliable module replacement
Adequate space for clear identification
Control of the outputs independent of the process
image
Functionality
No restart of the ET 200iSP necessary
Efficient monitoring of the inputs
Options for use in technological applications
Unique identification/assignment of the modules
used (for example, for validation, quality assur‐
ance)
