ACT20M passive isolator

ACT20M passive isolatorOne and two-channel passive isolators with 6-mm design
With its new ACT20M Weidmüller offers users the choice of a one or two-channel passive isolator with a six millimetre design. Passive isolators guarantee electrical isolation in signal circuits – without an additional power supply. The passive isolator is either input loop powered (ILP) or output loop powered (OLP). This makes it possible to electrically isolate both channels in a module design width of just 6 mm. This represents the simplest, most space-saving and cost effective method of isolation to protect connected devices, and also improves the quality of the signals. High process reliability is assured on the one hand by the electrical isolation of 2.5 kV (300 V rated voltage) and on the other by the high measuring accuracy of up to 0.1 percent.
