Analog input module with two channels for strain gauges and load cells

Resistance bridge circuits are used in various areas. Strain gauges, force sensors and load cells are typical examples. The new 2AI Resistor Bridge (strain gauge) analog input module enables such resistance bridges to be connected directly to the WAGO I / O System 750. It has two channels and provides the reference voltage directly in the module. This reduces the wiring effort and thus lowers costs. With an overall width of just 12 mm, the module also saves space in the control cabinet. With a resolution of 16 bits, the evaluation of the resistance bridges is very precise. The large input voltage range of ± 300 mV enables different types of sensors to be connected.

Your advantages:

• Connection of resistance bridges, load cells and strain gauges

• Two channels in a 12 mm wide module

• Less wiring effort thanks to internal reference voltage

Turck now offers special versions of its HMI/PLC devices for applications in the food and beverage industry and for use in bright ambient light

The TX700FB HMI/PLC device series is designed for applications in the food industry (FB for Food&Beverage). The also new TX700HB (High Brightness) version offers better sunlight readability in applications with direct sunlight incidence. Like the devices of the TX100, TX200, TX500 and TX700 series, both variants can not only be used for visualization but can also be used with Turck’s TX VisuPro without CODESYS as IIoT gateway or edge controller.

IIoT-Multitool: Communication via eight protocols in parallel

In addition to the classic HMI protocols for connection to controllers, such as those from Siemens, Beckhoff or Rockwell, TX VisuPro also supports MQTT or OPC-UA as server and client. The devices can communicate with up to eight protocols in parallel. This gateway function therefore also allows data to be exchanged between different controllers or end devices. 

Front side protection class IP69K for high pressure cleaning 

The FB devices were developed to comply with hygienic design requirements (DIN EN1672-2, EHEDG/FDA 21 CFR 177.2006) and come with a stainless steel front with a polyester coating. The device front has been designed with protection to IP69K so that the devices are waterproof at high pressure up to 80 °C. The FB products are also resistant to acids and chemicals.

Minimized reflections for outdoor applications

The HB devices with their extra bright display up to 800 Cd/m² are particularly suitable for outdoor applications. The displays are manufactured with liquid bonding (LOCA) – a screen bonding process that improves screen contrast and increases brightness through reduced reflection and refraction. The HB devices with the full metal housing are resistant to mechanical influences.

The PowerXL frequency converter DM1 combines high functionality in the smallest of spaces. It is used wherever space is an issue, but still requires the functionality of an ordinary universal converter. These include pump functions, HVAC functions and the control of common motors such as asynchronous motors or PM motors. Single-phase (115/230 V) and three-phase versions (400/600 V) are available that cover the power range up to 22 kW. The DM1 Pro version is equipped with safe torque off (STO) and extensive communication protocols as standard.

Key Features:

• STO – SIL2, PLd, Cat.3 (DM1 Pro)
• Integrated web server (DM1 Pro)
• Bluetooth on-board
• Short-circuit protection without additional ballasts

• U / f control, sensorless vector control, PM control

Space-saving installation in existing systems:

Thanks to its compact design, the DM1 also fits into small housings with a depth of only 200 mm. In addition, the small space requirement enables inexpensive installation within the cabinet.

The DM1 (basic version) is suitable for simple applications in which no additional controls are required. The DM1 is the basic variant and offers Modbus RTU on-board, U / f control, Bluetooth but without keypad, STO and option cards. The DM1 Pro is more extensively equipped and also offers extended functions. DM1 Pro functions at a glance: Keypad with 7-segment display and setpoint potentiometer, STO on-board, Modbus RTU, Modbus TCP, Ethernet IP, BACnet MSTP and BACnet IP on-board, U / f control, vector control, PM motor control, Bluetooth, web server on-board, slot for an option card.

The DM1 Pro does not require any external software, as the integrated web server enables access to all device settings and diagnostic data. The PowerXL inControl software includes a module for offline commissioning of the DM1 Standard and DM1 Pro. This module offers the same functionality as the web server and can be used if the DM1 has to be parameterized without a device being connected. The drive can also be put into operation with an external DG1 remote keypad, which can be connected to both the DM1 Standard and the DM1 Pro and shows all parameters and settings in plain text.

Did you know that no external supply is required while protecting your system from noise with the PISO series? The new PISO series has many input and output combinations, from 0-20mA at the input and 0-20mA, 0-5V or 0-10V at the output. Multi-channel models are also in the portfolio.

Pressure transmitters from Turck’s PT1000/2000 series are now also available with an IO-Link interface and two programmable switching outputs. Besides their ability to withstand shocks and changes in pressure and temperature, the sensors thus also offer all the benefits of digital communication, including enhanced diagnostics and flexible parameterization.

For example, IO-Link enables users to monitor electrical short circuits, overpressures and underpressures, as well as values exceeding the maximum operating temperature. Other data for efficient condition monitoring can be supplied by an operating hours counter, a maximum and minimum pressure memory and an overpressure meter.

The pressure transmitters can be operated with two switching outputs or with IO-Link communication and one additional switching output as required. These switching outputs can be set for either PNP or NPN operation. This makes it possible to set the location of the switch points within the measuring range and their behavior as required.

Turck offers the compact pressure sensors with protection to IP67 and IP69K in two different designs: PT1000 series transmitters cover a measuring range from 0…1 bar to 0…40 bar and operate with a ceramic measuring cell. PT2000 series devices are provided with fully welded measuring cells for higher pressure ranges. Their measuring range is 0…1000 bar. Regardless of the series, the pressure sensors offer users the benefit of a high measuring accuracy of ±0.3 % FS BSL.
