Note
Interface circuitry of an electricity meter has to withstand min. 15mA and min. 15V DC, both of which are applied by MIM-B16N.
Even though MIM-B16N interface circuitry is realized with electric isolation components, it’s highly recommended that interface
circuitry of an electricity meter be designed with isolation to ensure robustness from contact spike or electric interference
during wiring.
