| Descripción del artículo | Isolated safety barriers / surge protection switching input transistor output isolated safety gate, the switch contact from the danger area or close to the switch input signal, through the safety gate isolated transmission to the safety zone transistor output. Line fault detection is output by a separate relay and displayed by an LED light at the top of the module. The dip switch of the module is used to set the input and output in phase or reverse phase control, as well as to set on or off the line fault detection alarm indicator function. The product needs independent power supply, and the power supply, input and output are isolated |
