The output consists of an optically coupled solid state relay (SSR) and the input has an optocoupler. Both the
SSR and optocoupler have an isolation voltage of 1500 VRMS between the external terminals and internal
camera circuitry. The input is further protected with a serial 250Ω resistor and a debouncing circuit.
