Product Details

一、海湾GST-LD-8301控制模块特点 
GST-LD-8301输入输出模块模块用于现场各种一次动作并有动作信号输出的被动型设备如:排烟阀、送风阀、防火阀等接入到控制总线上。 
本模块采用电子编码器进行编码,模块内有一对常开、常闭触点。模块具有直流24V电压输出,用于与继电器触点接成有源输出,满足现场的不同需求。另外模块还设有开关信号输入端,用来和现场设备的开关触点连接,以便对现场设备是否动作进行确认。本模块具有输入、输出具有检线功能。应当注意的是,不应将模块触点直接接入交流控制回路,以防强交流干扰信号损坏模块或控制设备。

二、海湾GST-LD-8301控制模块主要技术指标 
(1)工作电压: 
 总线电压:总线24V 
 电源电压:DC24V 
(2)监视电流: 
 总线电流≤1mA 
 电源电流≤5mA 
 (3)动作电流: 
 总线电流≤3mA 
 电源电流≤20mA 
(4)线制:与控制器采用无极性信号二总线连接,与DC24V电源采用无极性电源二总线连接 
(5)无源输出触点容量:DC24V/2A,正常时触点阻值为100kΩ,启动时闭合,适用于12V~48V直流或交流 
(6)有源输出容量:DC24V/1A 
(7)输出控制方式:脉冲、电平(继电器常开触点输出或有源输出,脉冲启动时继电器吸合时间为10s) 
(8)出厂设置:常开检线输入、有源输出方式 
(9)使用环境: 
 温度:-10℃~+55℃ 
         相对湿度≤95%,不结露 
(10)外壳防护等级:IP30 
(11)外形尺寸: 
 86mm×86mm×43mm(带底壳)

三、海湾GST-LD-8301控制模块结构特征、安装与布线 
GST-LD-8301模块的外形尺寸及结构与GST-LD-8319输入模块相同,安装方法也相同,其对外端子示意图如图2-32: 

其中: 
Z1、Z2:接火灾报警控制器信号二总线,无极性 
D1、D2:DC24V电源输入端子,无极性 
G、NG、V+、NO:DC24V有源输出辅助端子,出厂默认为有源输出:G和NG短接、V+和NO短接当需无源常开输出:应将G、NG、V+、NO之间的短路片断开。 
I、G:与被控制设备无源常开触点连接,用于实现设备动作回答确认(也可通过电子编码器设为常闭输入或自回答) 
COM、S-:有源输出端子,启动后输出DC24V,COM为正极、S-为负极 
COM、NO:无源常开输出端子

布线要求:信号总线Z1、Z2采用阻燃RVS型双绞线,截面积≥1.0mm2;电源线D1、D2采用阻燃BV线,截面积≥1.5mm2;G、NG、V+、NO、COM、S-、I采用阻燃RV线,截面积≥1.0mm2。

四、海湾GST-LD-8301控制模块应用方法 
模块输入端如果设置为“常开检线”状态输入,模块输入线末端(远离模块端)必须并联一个4.7kΩ的终端电阻;模块输入端如果设置为“常闭检线”状态输入模块输入线末端(远离模块端)必须串联一个4.7kΩ的终端电阻。模块为有源输出时,G和NG、V+、NO应该短接,COM、S-有源输出端应并联一个4.7kΩ的终端电阻,并串联一个IN4007二极管。
