| 电动门报警探头输出信号接口的类型应为继电器输出接口供电电压应为直流12—15V否则不能由本控制器直接供电.探头耗电应≤100毫安.根据现场情况可配用多只探头(一般以1――2只为宜)多探头时采用并接方式.探头.应避免其他热源或直射光影响上方应加防雨罩. The type of output signal interface of electric door alarm probe shall be that the power supply voltage of relay output interface shall be DC 12-15v, otherwise it can not be directly powered by the controller. The power consumption of probe shall be ≤ 100mA. According to the site conditions, multiple probes (generally 1-2 are suitable) can be equipped. When multiple probes are used, the parallel connection mode shall be adopted. The probe shall avoid the influence of other heat sources or direct light, and rain cover shall be added above. |
