使用特性1、导体的直流电阻参照聚氯乙烯绝缘及护套电力电缆2、交流电压试验成品电缆经受交流50HZ、5min、3500V的试验电压不击穿,对于单芯电缆,应进行浸水耐压试验。耐火电缆和阻燃电缆分别符合耐火和阻燃性能要求。
在PLC系统中,常用的标准串行接口主要有RS232接口、RS422接口、RS485接口等。RS232/422/485为PLC系统最为常用的通信接口:RS232接口是一种计算机、PLC控制系统中最为常见的标准串行接口,接口一般使用9芯或25芯连接器,使用的信号名称、代号、引脚的意义如下表所示:RS422接口是一种计算机、PLC控制系统中常见的标准串行接口,称为“平衡电压数字接口”。接口一般使用9芯连接器,使用的信号名称、代号、引脚的意义如下表所示:RS-485接口是在RS-422基础上发展起来的一种标准串行接口,同样采用了“平衡差分驱动”方式。

BV line, BVR line, RVSP double stranded shielded cable, RVS double stranded cable, RVB parallel line, RV line RVSP Shielded twisted-pair cable RVSP (shielded twisted-pair cable, shielded cable, shielding twisted-pair electric (HYVP, RVVP) RVVP twisted-pair shielded cable < < shielded wire > > is shielded twisted-pair cable RVSP series on the basis of RVS coupled with a layer of copper wire shielding net, so the transmission loss, shielding the outside world better than RVS series, but because of the copper wire shielding network, its cost is also much higher than RVS series. Are often used to those who has a high requirement on the transmission. Technical indicators: polyvinyl chloride insulated cable long-term allowed working temperature over 70 ℃, the cable temperature under installation should not below 0 ℃, outer diameter (D) is less than 25 The allowable bending radius of mm cable shall not be less than 4 times the outer diameter of the cable. Diameter (D) of 25 mm and above of permissive bending radius of cable, not less than 6 times of cable diameter.

3.P<Imin(Emin-IminRLmax)变送器的最小耗费功率P不能超过上式,一般<90mW。式中:Emin=最低电源电压,对大都外表而言Emin=24(1-5%)=22.8V,5%为24V电源答应的负向改变量;Imax=20mA;Imin=4mA;RLmax=250Ω+传输导线电阻。若是变送器在规划上满意了上述的三个条件,就可完成两线制传输。所谓两线制即电源、负载串联在一起,有一公共点,而现场变送器与控制室外表之间的信号联络及供电仅用两根电线,这两根电线既是电源线又是信号线。
5.电缆允许弯曲半径:非铠装电缆最小为电缆外径的6倍,铜带屏蔽或钢带铠装电缆最小为电缆外径的12倍。煤矿用控制电缆使用特性:电缆导体的长期允许工作温度为70℃,电缆敷设温度应不低于0℃。电缆允许的弯曲半径:对有铠装或铜带屏蔽结构的电缆应不小于电缆外径的12倍。
