When used for industrial monitoring applications, sensors can record surrounding environmental conditions. Sensor signals are used within the process to continually track changes to the area being monitored.
Either digital or analogue signals can occur.
Normally an electrical voltage or current value is produced which corresponds proportionally to the physical variable that is being monitored.
Analogue signal processing is required when automatic processes are being monitored to ensure that they maintain or reach some defined state.
This is particularly significant for process automation applications. Standardised electrical signals are typically used for process engineering.
Analogue currents/voltages of 0(4)...20 mA/ 0...10 V have become established as the standard physical measurement value range.
Weidmüller's new products are in harmony with the growing trend towards automation. Our line of products for analogue signal processing have been designed with sensor signal requirements in mind.
These analogue signal processing products can be used in conjunction with other Weidmüller products and can be combined with one another.
Electrically and mechanically, they are designed so that they require a minimum of wiring effort.
These products can be adapted for a wide range of industrial and process automation applications – with housing and connection systems designed to fit the application.
The following functionality is included in the product line: - Isolating transformers, supply isolators and signal converters for DC standardised signals
- Temperature measuring transformers for resistance thermometers and thermocouples,
- Frequency converter
- Potentiometer measuring transducers,
- Bridge measuring transducers (strain gauges)
- Trip amplifiers and modules for monitoring electrical and non-electrical process variables
- AD/DA converter
- Displays
- Calibration devices
The products mentioned are available as pure signal converters, 2-way/3-way isolators, supply isolators, passive isolators or as trip amplifiers.

Relays are available in different forms – from modular terminal enclosures to plug-in bases for terminal rail mounting.
For switching and amplification of digital signals in automation engineering as well as for electrical isolation between control and load circuit.
The input voltages (coil voltage) lie between 5 and 230 V AC/DC depending on type. Different types of contacts such as NOC,
NCC and CO contacts are available at the output The use of different contact materials enables the switching of power ratings from just a few mW to max. 4 kVA.

The priority you give to overvoltage protection depends on your willingness to take risks! Perhaps you think "it’ll never happen to me". Then you won’t have lost anything, but will have gained only very little. However, the subject of overvoltage is then a daily worry for you. But if you wish to be on the safe side, you should include overvoltage protection in your corporate strategy. You will profit from such an investment in operational safety and can prevent a disaster with Weidmüller's surge protection for power, signal and data. |

The FBCon Fieldbus distributor is available in the industry and EEx (ia) version. They are used for coupling from 1 to 8 field devices or sensors.
They are connected via spur lines. The connection to the spur line can be made with an M12 plug or directly via an EMC cable gland.
Communication and device power feed are transferred by a common 2-wire line. The distributors offer the following features irrespective of the version:
- Tension-clamp connection system
- Overvoltage protection for the main line
- Current limiter for each branch line
- EMC cable gland
- M12 plug-in connectors
- External earthing contact
- Interruption-free bus operation
- Industrial version
- Bus termination integrated (not EX)
- ATEX explosion-proof version
- Pressure-equalising element
- Protection degrees IP65, IP66, IP67
- Stainless steel versions
- PROFIBUS-PA compatible

The interface components are available as a clear alternative to the point-to-point wiring system in order to reduce costs and to simplify the setup of the electrical cabinets. The main function of this interface is as an adapter between the control devices and field elements.
The interfaces consist of: - Standard connectors for connection to the control devices.
- PCB terminals with tension clamp or screw connections for the field connection.
- Additional components like LEDs, fuses, relays or isolators which can integrate new functions.
- Profiles and base frames for attaching to standard TS32 and TS35 mounting rails.
The pre-assembled cables supplied by Weidmüller are also used to connect the tester with the interface.
These are the advantages of the system: - Saves time during the installation.
- No risk of wiring mistakes.
- Shorter schedules for project planning.
- Improved order in the electrical cabinet.
- Saves space in the cable ducts.
- Small module widths.

Electrical parameters have to be measured and visualised to optimise your machines' and systems' energy needs. Only this allows analysis and, subsequently, the achievement of savings and the establishment of an energy management system.
An easy-to-install solution is now available from Weidmüller. When implementing an energy management system according to the ISO 50001 standard, the power monitor is one of the basic modules necessary for recording, visualising and analysing energy flows. - Existing systems and equipment can also be quickly retrofitted.
- All relevant electrical parameters within a 3-phase network can be visualised: measurement of current, voltage, power, energy consumption, active factor, apparent power and reactive power.
- Measurement recording is possible with conventional current transformers.
- The superior 4-line LCD display allows all important parameters to be read at a glance.
- Large soft keys ensure reliable navigation.
