ACT20M - Terminal Sized Signal Isolators & Converters

Control Engineering's 2012 Engineer's Choice Awards Winner!


High-quality signal isolation and conversion functionality in a 6mm 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 new ACT20M series provides time and cost savings when 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.

Weidmuller’s new ACT20M features two-channel, loop-powered isolation, signal splitting with power provided for the transmitter, or universal input conversion in a slim 6mm wide module – without compromising performance. The high isolation levels (2.5kV) and accuracy (<0.05%), combined with a wide ambient temperature range (-13°F 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. 


Weidmuller’s ACT20M models, with selectable voltage and current ranges, feature DIP switches. For the Universal input model, vendor-independent FDT-based configuration software is available for download on the Weidmuller Website. Regardless of the set-up method used, the calibration-free procedure saves the user time in getting the plant up-and-running.
