Et 200Isp In The Hazardous Area - Siemens SIMATIC ET 200iSP Operating Instructions Manual

Product overview

2.2 ET 200iSP in the Hazardous Area

Properties
Redundancy of the IM
Redundancy of the Power Supply PS
Fieldbus communication
If an IM 152-1DP is used in the station, all modules of the station can communicate with all DP
masters that are compatible with the "DP" transfer protocol according to
the IEC 61784‑1:2002 Ed1 CP 3/1 standard (DP stands for distributed I/O).
2.2 ET 200iSP in the Hazardous Area
Properties of zones
Hazardous areas are classified into zones. The zones are distinguished according to the
probability of the existence of an explosive atmosphere.
The ET 200iSP can be used in hazardous areas (Zone 1/ 21, Zone 2/ 22) and in the safe area.
You can connect intrinsically safe encoders, actuators and HART field devices to the ET 200iSP
which may be located up to zone 0/ 20 and in the safe area. The sensors, actuators, and HART
field devices must be certified for operation in the corresponding hazardous areas.
You will find an overview of the zone divisions in the following table:
Table 2-4 Classification of zones

Zone 0/ 20
Zone 1/ 21
Zone 2/ 22
