* Channel configuration refers to the directionality of the isolation channels. For products with integrated, isolated power, the second number corresponds to the number of inputs on the side with the isolated power. For example, "2/1" means two channels communicate in one direction while the third channel communicates in the reverse direction, with two inputs on the non-isolated supply side, and one input on the isolated supply side.
