| 适用范围 |
HOB-1防爆耦合器（户内安全区）
HOB-1防爆耦合器（户外危险区）
HOB-1多路防爆耦合器（户内安全区） |
| ●该产品放置在安全区，与程控交换机配套，信号输出至防爆区域防爆电话机、防爆电话站。 | |
| Application | |
| ●The
product is put in safety area and is the partnership of program switch.The
signal tranfer to explosion-proof telephone and station. |
|
| 产品功能 | |
| ●由于程控交换机输出电气参数未能达到本安电路要求，因此在程控交换机输出端和防爆电话机的输入端之间串接防爆耦合器进行多级限制保护措施，达到本安电路的输出要求，起到安全保护作用。 | |
| Product function | |
| ●Because the output of the program exchanger is not reach the increase safe requirement,so the coupling is used between the output of the program controlled exchange and the input of the explosion-proof telephone to realize the output of the coupling reach the requirement of increase safety |
