S7-300 SM Ex analog modules

For use within explosive plants

Description

In many branches there exist explosive environments in manufacturing and following processes.

To assure a preferably high level of safety in these areas, there exist conditions in terms of laws, orders and norms.

For the use in these areas, there are Ex modules that are endorsed intrinsically-safe sensors and actuators being in zone 1 or 2 of explosive plants.

Area of application

The Ex modules are available to the automation particularly of chemical plants as appropriate operating supplies. They are applicable for applications in the measurement-, control- and regulation technology.

Areas of application:

Chemical/petrochemical industry
Gas industry
Offshore industry
Transportation (e.g. tankers)
Automotive engineering (e.g. at varnishing)
Energy supply, energy distribution etc.
Generating plants
Special engineering (e.g. printing machines, cleaning machines)

Benefit

The igniting protection type intrinsically-safe offers following advantages to the user:

Easy interchangeability of intrinsically-safe equipment during the business
Easy measurement and calibration of the measuring section during the business
Working in intrinsically-safe energized loops without stop of the plant
No complex case execution (e.g. compression-proof encapsulation) necessary
Linking of intrinsically-safe equipment of different manufacturers possible
Approved igniting protection type in chemical industry

Design and functions

The main function of the analog Ex modules is the separation of the intrinsically-safe loops of the Ex field and the non intrinsically-safe internal loops of the automation plant.
The Ex analogl input modules transform the analog signals of the intrinsically-safe equipment in digital values for the following working.

The Ex analog output modules transform the digital signals of the automation plant in analog signals being necessary for the process.
Ex analog input/output modules are “appropriate electrical eqipment” of the igniting protection type intrinsically-safe (term [EEx ib] IIC according to DIN EN 50020). You get next to intrinsically-safe ones also non intrinsically-safe loops.

Same systems engineering as the other modules of S7-300
Galvanic separation of the module
Confusion safety through coding
Supply of the sensors and actuators through the module
Direct wiring of the inputs and outputs of the modules without a separating switch amplifier or transmitter feed unit
Different wiring of the software possible
Diagnosis capable modules
Reduced planning, installation and documentation effort
Operation also with ET 200M possible with connection to all SIMATIC automation systems and as norm slave to all PROFIBUS DP networks.

S7-300 SM Digital modules

S7-300 Signal modules

Description

Digital actuators and sensors can be connected to a SIMATIC S7-300 via digital modules. The extensive range of modules allows the most suitable signal module to be selected in each case.

Area of application

Digital input/output modules contain digital inputs/outputs for the automation system. Digital sensors and actuators can be connected to the automation system via these modules. Switches and 2-wire proximity switches (BEROs) can be connected to input modules, for example. Output modules are suitable for connection of solenoid valves, contactors, small motors, lamps and motor starters.

Benefits

The use of digital input/output modules provides the user with the following advantages:

Optimum adaptation;
since almost any combination of modules is possible, the number of inputs/outputs can be matched to suit the task in hand. Superfluous investments no longer exist
Flexible process connection;
the wide variety of digital actuators and sensors facilitates connection of the automation system to the process

Design and functions

Digital input/output modules exhibit the following mechanical characteristics:

Compact design
The rugged plastic housing features:
• Green LEDs for displaying the signal states at the inputs/outputs
• Slot for the front connector, protected by the front cover
• Labeling area on the front cover

Easy assembly
The modules are mounted on DIN rails and connected to adjacent modules via bus connectors. There are no slot rules, the input addresses are determined by the slots.

When used in the ET 200M distributed I/O station together with active bus modules, the modules can be hot-swopped during operation without affecting the other modules.

User-friendly wiring

The modules are wired by means of a front connector. When they are first plugged in, a coding element clicks into place so that the connector will only fit into modules of the same type. When the module is replaced, the front connector can be used in its fully-wired state for a new module of the same type.
