NETWORK TECHNOLOGY Connecting your Ex area to the 21st century is this simple.

Digital progression is transforming whole industries and will inevitably become a key measure of competitiveness for companies in the future. Also in process automation, new and more efficient solutions for the digitalisation of plants are in development. For this purpose, R. STAHL is also actively involved in working groups such as NOA (NAMUR Open Architecture) and OPAF (Open Process Automation Forum). Ethernet and wireless technology are intended to play key roles in the implementation of digitalisation concepts in the process industry. Their main applications will be in data transmission...

The use of Ethernet in the process industry gives rise to an aspect that for most IT experts is absolutely new - explosion protection. Protective regulations in the form of laws, decrees and standards have been adopted across the world to prevent explosions. The primary aim is to prevent the formation of dangerous explosive atmospheres. In the production areas of the process industry, this often cannot be completely excluded. Measures are therefore required that prevent the ignition of this atmosphere. Potential For an explosion to take place, these three factors need to be present at the...

MEDIA CONVERTER, UNMANAGED AND MANAGED SWITCHES Ethernet data transmission via copper cables is limited to a distance of about 100 m. This is frequently not enough for the large production sites in the process industry. Also, data transmission via copper cables can be affected by electromagnetic interference. In both cases, data transmission via optical fibre is a suitable alternative. R. STAHL's media converters and switches work on the basis of explosion-protected laser sources, making installation and operation very simple. -s.

Unmanaged switch 9721 The switch 9721 is used for linking electrical Ethernet networks with optical 100 Mbit/s Ethernet networks. The 4 FO ports are designed for operation in the hazardous areas with the „op is“ type of protection. This way, conventional fibre optic cables can also be used in hazardous areas and may be connected and disconnected during operation (hot swap). • Transmission rate 100 Mbit/s. • Transmission range up to 5 km (multi mode) or up to 30 km (single mode). • Extended temperature range: -30 °C ... +70 °C. • Suitable for installation in Zone 2. Managed switch 9722 The...

INSTALLATION TECHNOLOGY FOR CABLES AND FIBRE OPTICS The installation of Ethernet in hazardous areas is a balancing act between the requirements of explosion protection and those of digital signal transmission. Whilst minimum distances and separate circuits are required on the one hand, parallel wiring may on the other hand result in interference. The known installation methods from the industrial area like RJ45 connectors or FO patch panels are not easy to use in hazardous areas. R. STAHL provides unique solutions that combine both worlds, while at the same time making installation simple...

Ethernet terminal 8187 Ethernet terminal 8187 is used to connect CAT5/6/7 cables with transmission rates of up to 1 GBit/s in Zone 1 hazardous areas and replaces the not permitted industrial connectors. • Simple installation in Zone 1 in the Ex e enclosure. • For transfer rates of up to 1 GBit/s on up to 4 pairs of wires. • High-quality shield for interference-free transmission. • Also suitable for Power over Ethernet (PoE). Fibre optics splice cassette 8186 Fibre optics splice cassette 8186 with „op pr“ type of protection is used to connect 6 or 12 fibre optic cables quickly and correctly...

INSTALLATION TECHNOLOGY FOR WIRELESS SOLUTIONS Wireless technologies such as WiFi are being used more and more frequently in the process industry. When used in hazardous areas, ignition protection for the wireless interface can be particularly challenging. The best balance between explosion protection and ease of use of the antennae is achieved by converting the radio signal to an intrinsically safe radio signal. This allows the planner and user to choose from the entire range of antennae and plug connectors that are suitable for industrial applications. „i“ type of protection – intrinsic...

HFisolator 9730 The HFisolator 9730 series from R. STAHL, which can easily be switched between a wireless device and an antenna and vice-versa, converts the radio signal into an intrinsically safe signal. R. STAHL offers two versions of this device, as a simple signal converter or a combined signal converter and coax bushing. • Use the entire antennae spectrum. • Additional frequency range. • Temperature range: -40 °C ... +80 °C. Antennae Converting the signal into an intrinsically safe antennae signal means that the HFisolator is able to use the entire range of industrially capable...

R. STAHL offers solutions to operate network components of your choice in hazardous areas - this includes devices that do not have corresponding approval. Enclosure system 9851 allows us to supply this solution in a short time. The advantages of a WiFi network really come to the fore when a network is managed uniformly across the company under central administration. Housing system 9851 enables the use of standard WiFi access points.

„nR“ type of protection – restricted breathing enclosure These enclosures are designed to limit the potential ingress of explosive atmospheres. When these housings are used in a simple design, the user must test their impermeability at regular intervals. Housing system 9851, combined with a connection chamber, is designed to make these user tests unnecessary. FLEXIBLE STRUCTURE – INTERNAL OR EXTERNAL ANTENNAE The use of plastic enclosures means that the use of external antennae is not absolutely necessary. This also makes it possible to use devices that only feature an internal antenna, as...
