These compact modules require only 11 mm per channel and take up very little space in the electrical cabinet. Weidmüller has specifically designed the ACT20X line for process automation applications in Ex and non-Ex zones. The 17 different variants can process all standard input signals (such as 2-wire, HART®-, NAMUR-, RTD, thermocouple or DC signals) from Ex zone 0. They can also handle digital or analogue signals from Ex-zone field devices to the controller. The integrated relay output issues an alert in the event of a malfunction; this makes troubleshooting easier and reduces facility down times. The WI-Manager configuration software is based on FDT (Field Device Tool) technology. The software allows you to configure all ACT20X products with your PC so that they can be custom-fit to a wide variety of process applications. Weidmüller provides a device type manager (DTM) for the ACT20X modules that can be used in any FDT-based frame. The DTMs allow you to configure different devices quickly and accurately. They also enable you to analyse measurements and diagnostics data. The DTM can also be used to clearly identify the connected device. The FDT frame application “WI Manager“ and the device-specific DTMs are available from Weidmüller free of charge. The ACT20X modules can be used in a temperature range from –20 °C to +60 °C without limitations. The modules can be installed in the safe zone or in the explosion risk area of Zone 2. The ACT20Xs always deliver a pure, interference-free signal B B.2 thanks to their accuracy, temperature stability and high insulation strength. They can easily be used around the globe since they already have all the necessary international approvals, including ATEX, ICEEX, GOST and FM. The newest member of the ACT20X family is the ACT20XHUI-SAO-LP. This offers an intrinsically safe input for 0/4 to 20 mA, 0 to10 V, temperature and resistance signals, and separates the Ex zone from the safe zone. The narrow 12.5 mm module is supplied via the 4 to 20 mA output. Features •International approvals for Zone 0, 1 and 2 (IECEx, ATEX) and Class 1 Division 1 and 2 (FM) •Analogue and binary signal interface to Zone 0/Div.1 for explosion-risk inputs and outputs •All standard input signals (4 to 20 mA HART®-, NAMUR-, RTD- or thermocouple signals) out of Ex zone 0, 1 or 2 •Two-channel type saves space in the electrical cabinet and reduces installation costs •HART® transparent signal isolator • Integrated alarm contact •Configuration over FDT/DTM standard with the frame application “WI Manager“ 2028820000 Intrinsically safe signal conditioners for hazardous area applications Intrinsically safe signal conditioners for hazardous area applications – Overview B ACT20X 2028820000 B.3 Intrinsically safe signal conditioners for hazardous area applications ACT20X – Overview ACT20X – intrinsic safety signal conditioners for hazardous areas PC-configurable conditioners family for hazardous areas in the new Weidmüller electronics housing for installation in safe or hazardous areas. B ACT20X meets the arduous requirements of the process industry where potentially explosive fluids are controlled. The range connects to sensors and actuators in the hazardous area, isolates their signals and limits the energy passed to them. On the input side ACT20X models can process d.c., B.4 temperature, Namur and volt-free contact signals. On the output side field devices in the Ex area are controlled via the ACT20X with analogue or digital signals. All ACT20X products are characterised by insulation, accuracy and high temperature stability. The digital 2-channel versions with width of 22.5 mm are available with either transistor or relay output. Due to this high component density, the space requirements and installation costs are reduced accordingly. 2028820000 Intrinsically safe signal conditioners for hazardous area applications ACT20X – Overview Configuration via FDT All modules can be quickly and conveniently configured with manufacturer-independent FDT/DTM software. \ ; " Worldwide application Fulfils the strict standards and requirements of the process industry. Can be used worldwide due to international and local approvals ATEX, IECEX, CULUS, FM, GOST and DNV. Intelligent connection system Pluggable, coded, with release lever. The release lever simplifies maintenance and allows disconnection without damaging the cables. Alarm function No laborious troubleshooting. Alarm function integrated for cable or sensor errors.
