Abstract
A common-mode interference dissipation circuit to provide circuitry immunity to electrical interference, such as common mode impedance interference, is described herein. The common-mode interference dissipation circuit may include one or more variable resistors each having a first terminal and a second terminal and a capacitor coupled in series with the one or more variable resistors and having a first terminal and a second terminal. The first terminal of the one or more variable resistors may be coupled to a port of the first set of ports, the second terminal of the one or more variable resistors may be coupled to the first terminal of the capacitor, and the second terminal of the capacitor may be coupled to a chassis in an industrial automation environment.
