Decentralised collection of sensor and actuator signals

Weidmüller's remote I/O systems for protection degrees IP 20 and IP 67 offer flexibility in the design and cabling of your systems, and much more.
The rise in complexity of machines and systems is placing increasing demands on modern automation technology. Branched sub-systems need to be precisely integrated into complex topologies. A rapid and reliable transmission of signals and data is critical for smooth operation. Small and adaptable components which can be integrated in an application-specific manner are needed. Flexibility in the design and cabling of your systems, reliability in the transmission of signals and data, and very compact solutions - Weidmüller's remote I/O systems for protection degrees IP 20 and IP 67 offer all this and more.
In both machine and plant construction, sensors and actuators from the entire machine have to be connected to the control unit. Depending on the machine, the size and also the count of the signals may be very large and therefore fieldbus and IO systems can be used to collect the signals locally. The progressive decentralisation requires more automation systems to be brought out from the control cabinet into the field, but decentralising machine automation can prove challenging for I/O systems’ mechanical properties. IP67 remote I/O modules are used wherever there are increased requirements in terms of particle and humidity protection. Indeed, they should offer high performance. But at the same time, they must remain robust, small and as light as possible, so they can be put to good use on moving machine parts.
u-remote’s new IP67 family combines all the field benefits offered by u-remote IP20 in a device with an increased degree of protection and is perfectly equipped for signal connection outside of the panel. In the variants with a sub-bus system, this is done very flexibly and in a wide range of applications. Direct incorporation in the PLC programming environment, rapid definition of causes in the event of faults and a very narrow and lightweight design are the characteristics which make this system unique on the market.
It is not only the manufacturing processes within machine construction that are complex. Companies that want to make worldwide deliveries to customers are frequently confronted with specific challenges. The Weidmüller u-remote IP67 product family makes sure that you are ideally equipped for international operations. When selecting the power supply, you have the simple choice between a 7/8? connection or an M12 connector with L-coding.
The coded connections help ensure that no mistakes are made during cabling. What’s more, the power supply, fieldbus and I/O components are colour-coded, which facilitates intuitive working. The use of Weidmüller module markers helps to make work even easier, particularly for customers that do not have any specialist staff on site.
Smart inventory reductions are available as multi-protocol modules and mean you no longer need to use different modules for PROFINET and Ethernet/IP. You simply have to select the fieldbus using the rotary switch. Both fieldbus systems can be operated with an L-coded M12 connector or 7/8“ connections, with only a cable set being needed in both cases. This helps to reduce the number of items used and orders made, as well as simplifying your warehousing processes.
Featuring I/O link technology, flexibility is greatly increased. u-remote IP67 ensures the greatest degree of flexibility in the different types of connections and solutions that can be used. This means that you are able to easily connect the corresponding IO link sensors and actuators. Alternatively, the channels can also be configured as standard digital inputs and outputs or you can use analogue IO link sensors and actuators. This allows for more functions to be mapped to an individual module, which often results in the capacity being able to be increased. The two compact and lightweight designs simplify the planning of installation surfaces and cable routing.
The more complex a production process becomes, the greater the number of processing stages that need to be coordinated. A large number of sensors and actuators within the production facility are connected with the central control system. In many cases, these connections have to cover great distances and involve the processing of many different signals. When employed in such connections, u-remote IP67 ensures maximum power in the system. The M12 L-coded connectors provide a 16A power supply – i.e. more power in the system – and need fewer power-supply units, which means that much less time and effort needs to be spent on cabling.
A fully encapsulated zinc die-cast enclosure protects electronics from vibrations, welding sparks and moisture during operation making them perfect for industrial environments. With compact features in both 60mm and 30mm wide designs, they are particularly suited to confined spaces. Even the short length of the modules and their low weight are to be highlighted as they offer advantages for many applications.
