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

IEEE tags
Redundancy of IM 152 (V2.0 and higher)
Redundancy of the power supply PS
DP master
All ET 200iSP modules support communication with DP masters that are compliant with
IEC 61784-1:2002 Ed1 CP 3/1 and operate with "DP" transmission protocol (DP stands for
distributed peripherals or distributed I/O).

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 the Zone 1/ 21, Zone 2/ 22 hazardous areas, and in the safe
area.
ET 200iSP supports the connection of intrinsically safe sensors, actuators and HART field
devices located in 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:

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