Analog Signal Isolators, Conditioners, and Monitoring Modules

Weidmüller’s range of analog converter and monitoring relays makes it a powerful partner in light of the increasing use of automation. Analog signal processing is required when automation processes have to constantly maintain or reach defined conditions. This is particularly significant for process automation applications. Standardized electrical signals are typically used for process engineering. Analog standardized currents/voltage 0(4) mA...20 mA/0 V...10 V have established themselves as physical measurement and control variables.

The analog signal processing products can be used universally in combination with other Weidmüller products and each other. Because of increasing automation, isolating amplifiers that convert, isolate, monitor, protect, and visualize users’ digital and analog signal values from industrial and process automation, e.g., temperature, pressure, level, flow volumes, weight, and speed are required.

Weidmüller’s signal converters for DC standard signals, 4 mA to 20 mA and 0 V to 10 V isolating amplifiers, switching amplifiers, frequency converters, and threshold switches are characterized by a high level of accuracy, universality, and a wide assortment of variants. The ACT20M series of products combines innovative technology with maximum functionality in an electronics housing measuring just 6 mm in width. The ACT20-FEED-IN-PRO-S power-feed unit eliminates the need to wire the power supply to the modules. This reduces the installation time by at least 30%. The ACT20-FEED-IN-PRO-S can supply and monitor up to 120 devices, which are mounted on the CH20 terminal rail bus.

The product line consists of input loop powered, output loop powered, and auxiliary powered analog isolators and converters, including a universal input converter. The eight-connection housing allows additional functionality such as two channel ILP, two channel OLP isolation, and signal splitting with input powering option. The configuration is carried out via DIP switches or the FDT/DTM software. The ACT20M modules are supplied via direct wiring or a rail bus.
