EC: ACT20M Series of Signal Isolators and Converters

Network integration – Signal conditioning, diagnostics: The ACT20M Series from Weidmuller provides high-quality signal isolation and conversion functionality in a 6-mm-wide housing. This is a Control Engineering 2012 Engineers’ Choice award winner.


ACT20M Series of Signal Isolators and Converters. The ACT20M Series provides high-quality signal isolation and conversion functionality in a single, 6-mm-wide housing. This is a Control Engineering 2012 Engineers’ Choice finalist.High-quality signal isolation and conversion functionality in a 6-mm-wide housing is now available with Weidmuller’s new ACT20M signal conditioner series. Featuring worldwide approvals for both normal and hazardous area installations, this new series of eight single and dual-channel models extends the broad functionality of Weidmuller’s signal conditioning portfolio with a package of solutions for industrial process measurement and control applications.

The ACT20M series provides time and cost savings for users building control panels. DIN-rail mountable and housed in Weidmuller’s high-technology CH20 housing, the ACT20M module offers the option to distribute power through the rail, minimizing power wiring and reducing installation costs. The Power Rail accommodates the addition and removal of individual modules quickly and simply, without affecting the wiring or operation of other components on the rail.

ACT20M features two-channel loop-powered isolation, signal splitting with power provided for the transmitter, or universal input conversion in a slim 6-mm-wide module without compromising performance. The high isolation levels (2.5 kV) and accuracy (± 0.05%), combined with a wide ambient temperature range (-13 to 158 F) and minimal temperature coefficient, make ACT20M a great solution for either the control room or the field enclosure, including Division 2 or Zone 2 areas. ACT20M models with selectable voltage and current ranges feature DIP switches. For the Universal input model, a vendor-independent FDT-based configuration software is available for download on Weidmuller’s website. Regardless of the setup method used, the calibration-free procedure saves the user time in getting the plant up-and-running.
