The Ex modules are available as associated equipment for the automation of chemical plants. They can be used for instrumentation and control applications.

Fields of application:

• Chemical/petrochemical industry
• Gas industry
• Offshore technology
• Transport (e.g., oil tankers, tank trucks)
• Automotive industry (e.g., in paintshop)
• Power supply, power distribution etc.
• Power stations
• Specialized mechanical engineering (e.g., printing machines, industrial cleaning machines).

The modules may not be used in areas subject to explosion hazard, unless they are additionally protected by another type of protection (e.g., pressurized enclosure).

The modules are approved for the connection of intrinsically-safe sensors and actuators located in Zone 1 or Zone 2 of areas subject to explosion hazard.

The modules can be used:

• In the SIMATIC S7-300 programmable controller
• In the ET 200M remote I/O device, can be used as distributed I/O for all SIMATIC S5/S7/505 programmable controllers and as a standard slave on all PROFIBUS DP networks
