Each of the new towers has 20 illuminated segments that can either be independently controlled or grouped, allowing a wide range of signalling functions to be achieved. The range also includes versions with an integrated audible siren that can be used to draw attention to alarm conditions. In addition to this, there are two further operating modes. In signal mode, the illuminated segments are arranged in five groups – so this could, for example, be used to show the progress of an operation or process. In level meter mode, the light tower is configured as a bar graph display, and could be used to provide an indication of the level of fluid in a tank or the temperature of a kiln, for instance. In level meter mode, the display colour can be used to show that a threshold or alarm level has been reached. There are currently four versions
The NEH2000BY is a high-performance power management
available, all of which feature an IO-Link interface for set up and control. The DV2900 has an integral mounting base, while the DV2910 has an integral mounting base and an integral buzzer. The corresponding versions without mounting bases are the DV2920 and DV2930 respectively. Wall brackets and other mounting aids are available as optional extras.
integrated circuit (PMIC) which recharges a battery or storage capacitor using energy harvested from ambient sources, such as light. As a result, it will enable the development of electronic devices that are self-powered, smaller, and environmentally friendly. Another benefit, the company claims, is that it makes it easier to design energy harvesting solutions which can be up to 20x smaller and do not require manual optimisation for individual applications. The PMIC was designed without inductors, simplifying PCB design, and significantly reducing overall BOM and board size, with a 12mm² assembly area. The NEH2000BY performs Maximum Power Point Tracking (MPPT), an adaptive algorithm that combines speed with accuracy, allowing the PMIC to adapt to environmental changes in less than a second. According to the company, it makes it easier for designers to power devices with ambient energy. It is available in a 16-lead, 3 × 3mm QFN package and operates between -40°C and +85°C.
