Switch up to eight 230V circuits via network

Wuppertal-based Wiesemann & Theis GmbH has expanded its range of network-based 230V remote control connectors with two products with potential-free closing and switching contacts for load currents of up to 16 amps.

"Web-IO 4.0 230V relay 1xNO, 1xCO" switches one closure and one switch up to 16 amps each. The big brother, "Web-IO 4.0 230V relay 4xNO, 4xCO", switches four NO switches and four PDTs with up to 6 amps per second. Channel.

The industrial network relays are installed on a 35 mm DIN rail. They can be accessed and controlled over the network. In addition to the web interface and apps for iOS and Android, various communication protocols are available for data access: Modbus / TCP, OPC, MQTT and REST support integration with Industry 4.0 and SCADA applications. Via TCP, UDP, SNMP and FTP, integration into other network products is possible.

Web IOs meet high security requirements. The individual network services can be activated independently. For each operating mode it is possible to determine which outputs are allowed to switch. An overview page contains information about active services and assigned channels. Web interface access and email sending are TLS encrypted upon request.

Web-IO with a closer and a switcher (# 57832) is now available at a net price of € 198.00 (DKK 1,485.00). The four-changer model and four cabinets (# 57383) cost € 298.00 (DKK 2,235.00). Commercial users can test the products for four weeks without obligation.

Active Communication has been a distributor for the Nordic countries for Wiesemann & Theis GmbH since 1992. W&T was founded in 1979 by Reinhard Wiesemann and Rüdiger Theis. With 50 employees, the company produces microcomputer and network technology in Wuppertal. In 2001, Wiesemann & Theis introduced the first industrial temperature sensor with network interface with the Web thermometer and has more than fifteen years of experience in the areas of Industry 4.0 and Internet of Things.

W&T Microwall:
Small firewalls protect devices and machines in the network
Microwall Gigabit from the Wuppertal network specialist Wiesemann & Theis marks the start of a new selection of user-friendly security products for industry and manufacturing. The small firewall isolates potentially vulnerable or non-secure devices and machines in their own network segments. Communication with these secure islands in the network is limited to the cases necessary to ensure operation. This effectively prevents attacks on open TCP or UDP ports as well as unwanted data connections.

The Web-Thermo-Hygrometer ++ from Wuppertal Wiesemann & Theis GmbH records and monitors measured values ​​for temperature and humidity and provides them via various network interfaces. The drift-free humidity sensor has no saturation effects and is therefore suitable for precise long-term measurements even in environments with permanently high humidity. With deviations of only 0.1K and 0.5% RH both sensors are very precise.

To create a good indoor climate in a room, the temperature and air quality in the room must be optimal. The temperature is usually controlled, but when it comes to air quality, there are often problems. Many people ventilate the air in the room either manually or through ventilation systems without controlling the air quality. The result often becomes unnecessary energy to ensure a good air quality and ventilate when this is not needed.

USB Devices Easily And Quickly Anywhere On The Net

The Gigabit 2.0 USB server integrates a USB device into the network via TCP / IP Ethernet for industrial use. The devices connected to the USB server Gigabit 2.0 behave exactly as if they were connected directly to your Windows PC.

Make automation easier and faster !!!

Are you involved in exploring new effective methods for managing the automation process - if YES - then you must learn pure.box and Google Go to know.
pure.box is a small server for industrial communication and automation, and it does not fill more than 105 x 75 x 22mm.

In recent months, Wiesemann & Theis GmbH has prepared the network-based remote control units and the Web-IO family sensor for thorough inspection. Web-IO 4.0 is now available and offers, in addition to new protocols and enhanced security, a new and simplified user interface.
New communication channels have been added to configure the necessary protocols and interfaces, such as email or MQTT. It is easy to decide how the Web-IO device should behave against a particular state or event. It may be that it should send an email if the temperature becomes too high - or turn off a digital output upon receipt of an MQTT subscription.

Terminal devices in the Internet of Things generally have no public IP address, but rather are connected over private networks. Cross-network connections can be opened only in the outgoing direction without a lot of additional effort. This eliminates peer-to-peer connections as a communication channel for the Internet of Things.

The solution is provided by the protocol MQTT: Terminal devices open a connection to a publically accessible messaging service, the broker. Here they can as publishers publish information and as subscribers subscribe to it.

January 1, 2017, we introduced this new updated website designed and developed by the company Infoicon Software, a collaborate as we certainly can recommend.
Our goal is to build a website and shop tailored to our customers needs. The site is primarily suited to our corporate clients to ensure a quick overview of the products we can offer. Here below is tab with impotent news you will meet in this website:
