Increase availability through improved, preventive maintenance.

In accordance with the IEC 60204-1 standard, measures must be taken to reduce the probability of malfunctions due to insulation faults / earth faults in a control circuit. A widely used option is the connection of 0 V to the earth potential in the control circuit, connected to an upstream fuse. With the new earth resistance signaling module, WAGO now offers the possibility, in addition to the 0V earthing, to also fully automatically detect the undershoot of a non-adjustable, asymmetrical insulation resistance between +24 V or 0 V of the supply voltage and earth. The Iso-OK status can be signaled to a controller with an integrated potential-free contact. In addition, LEDs on the module clearly indicate the insulation fault to the operator. This significantly simplifies maintenance compared to mechanical earth wire disconnect terminals. Instead of the previously usual manual test of an earth fault about every 3 months, there is now a permanent test of the insulation resistance. Early detection of impending earth faults enables improved preventive maintenance and thus ensures increased system availability. The user can select the grounded / ungrounded control circuit operating mode using a slide switch; however, the module does not meet the requirements for insulation monitoring devices according to IEC 61557-8.

Benefits:

Automated measurement of insulation resistance

Early detection of looming earth faults

Signaling of insulation faults via LEDs and potential-free contacts

The new LRS510 sensor family from Turck offers comprehensive analysis functions for demanding level applications in tanks and silos.

Radar sensors of the recently developed LRS series with IO-Link complement Turck’s portfolio for level measurement in the range from 0.35 to 10 meters. New devices with IP67 / 69K protection are particularly recommended for factory automation level applications where optical or ultrasonic sensors are unsuitable due to disruptive factors such as dust, wind or light. Free-emitting LRS radar sensors offer detailed analysis functions that were previously only possible in modern radar sensors in the process industry. The lack of a metal guide probe makes it easier to use the sensor in hygienic applications and simplifies commissioning

The capacitive keys and the touch surface of the LRS series, with their translucent front cover, are based on the same concept as the Fluid 2.0 sensor platform from Turck and transmit data on distance, level and volume values. LRS sensors are available with two digital outputs or one digital and one analog output. Thanks to additional IO-Link interfaces and signal preprocessing, all variants offer a large amount of additional information for processing in condition monitoring applications on IIoT. In addition to the signal strength, this also includes temperature values, operating hours or switching cycles.

Turck’s IO-Link master users can call up the radar monitor via the IODD configurator without the need for additional software. The browser-based configuration tool shows the measurement curve of the sensor graphically and offers plain text access to all relevant parameters. This makes it possible, for example, to mask the interference signal from a mixer or network or to align perfectly with the real-time feedback from the sensor in order to maximize the reliability of the level measurement in demanding applications.

Comprehensive energy measurement is necessary to optimize energy consumption. WAGO now has new energy meters in its portfolio that offer numerous advantages. You use the Push-in CAGE CLAMP® with a lever and can therefore be connected very easily and quickly. The devices are only 72 mm wide with direct measurement and even only 35 mm in the version for current transformers. This saves the user a lot of space in the control cabinet.

In addition to the values ​​for active and reactive energy, the energy meters also record grid frequency as well as current, voltage and power for all phases. The user sees all energy quality features at a glance on the large, illuminated display. The new energy meters are real communication professionals. All devices have both an M-Bus and a Modbus® interface that the user can use as required. In addition, two S0 interfaces are available for both energy directions, with the pulse rate being adjustable. The configuration and operation of the new meters is very easy: The large display facilitates operation via the integrated sensitive operating elements. In addition, a configuration app can be used that communicates with the device via Bluetooth®. With the new energy measuring devices, a wide variety of applications in buildings or in industry can be implemented – the MID declaration of conformity also enables applications with consumption billing.
