Siemens SIMATIC ET 200iSP Operating Instructions Manual page 15

Area of application
The ET 200iSP distributed I/O station can be operated in potentially explosive atmospheres
characterized by gas and dust:
Approval
ATEX
IECEx
* In combination with an appropriate enclosure
** for electronic module 2 DO Relay UC60V/2A: up to Zone 1, Zone 21
The ET 200iSP distributed I/O station can, of course, also be used in the safety area.
You can insert almost any combination of ET 200iSP I/O modules directly next to the interface
module that transfers the data to the DP master. This means you can adapt the configuration
to suit your on-site requirements.
Every ET 200iSP consists of a power supply module, an interface module, and a maximum of
32 electronic modules (for example, digital electronics modules). Remember not to exceed the
maximum current consumption.
Terminal modules and electronic modules
In principle, the ET 200iSP distributed I/O device consists of various passive terminal modules
onto which you plug the power supply and the electronic modules.
The ET 200iSP is connected to PROFIBUS RS 485-IS by means of a connector on terminal
module TM-IM/EM. Every ET 200iSP is a DP slave on the PROFIBUS RS 485‑IS.
