西门子总线电缆 西门子PROFIBUS-DP通讯线 若供水量减小,管网水压会升高,此时又需人工切除水泵。在深夜用水量较小时,为节能考虑用一台90kW水泵供水。由于水泵的流量较大,为避免“水锤”效应,人工投切时,投入泵时应遵循“先开机,后开阀”、切除泵时应遵循“先关阀,后停机”的操作程序。若是小功率的水泵,水泵的出水侧都装有普通止回阀,其本上能自动保证以上的操作程序,只是停机时止回阀关闭前的瞬间还是有“水锤”效应产生,如果安装的是“微阻缓闭止回阀”,停机时基本上也不存在“水锤”效应。 上海晋营自动化科技有限公司 联系人:邵泽春 电 话: 传 真:021-37605857 邮 箱:3117125529@ Q IE FC TP 标准电缆 GP 2 x 2: 专门为快速装配而设计、带有刚性芯线的标准总线电缆; 4 根硬线绞合成的 4 线绞合电缆 IE FC TP 耐用型标准电缆 GP 2x2: 标准的实芯总线电缆,专门针对快速安装而设计; 4 个实芯线,连接在 4 路星形分配器上,带坚固耐用的 TPE 外护套(热塑弹性材质制成) IE FC TP 软电缆 GP 2 x 2: 用于临时运动特殊应用的软总线电缆; 4 根绞线合成的 4 芯绞合电缆 IE FC TP 耐用型软电缆 GP 2x2: 软质总线电缆,专门针对临时性运行控制应用而设计; 4 个实芯线,连接在 4 路星形分配器上,带坚固耐用的 TPE 外护套(热塑弹性材质制成) IE FC TP FRNC 电缆 GP 2 x 2: 在建筑物内使用柔性、无卤素电缆(FRNC= 阻燃无腐蚀性);四条导线(柔性导线)被绞合成星绞四线组以便于偶然移动 IE FC TP 拖缆 GP / IE FC TP 拖缆 2 x 2: **于在轨道链中受力运动导引的较软总线电缆,例如在连续运动的机器部件中;4 根绞合线组成的 4 芯绞合电缆 IE FC 吊缆 GP 2 x 2: 在电缆拖曳/吊挂连续移动中使用的**柔性电缆,例如,在起重机系统中使用;四个线芯(标准)绞合为四线组 IE TP 抗扭电缆 2x2: 用于连续运动控制系统的较软总线电缆,例如用于机械手;绞合导线 IE FC TP 食品级电缆 2 x 2: 食品与饮料工业中使用的**柔性电缆; 四个线芯绞合为四线组 IE FC TP 食品级坚固电缆 2 x 2: 食品与饮料领域中使用的**拖曳电缆 (IP69);四个线芯,绞合为四线组 IE FC TP 船用电缆 2 x 2: 船用总线电缆;4 根绞合线组成的 4 芯绞合电缆,无卤素,船级社认证 IE TP 接地电缆 2x2: 用于在土中固定布线的总线电缆,四根硬线绞合组成的 4 芯绞合电缆,附加外部 PE 护套(内部 FC 电缆设计) IE TP 铁路电缆 2x2: 用于铁路等特殊应用的总线电缆,四根线(镀锡绞线)绞合组成的 4 芯绞合电缆,经认证用于铁路应用 产品概述 IE FC电缆 2 x 2(与 PROFINET 兼容,符合“PROFINET 电缆布线和互连技术指南”1)) 西门子总线电缆 PROFINET:A 型 西门子总线电缆 PROFINET:B 型: AWG 22/1 高质量布线 适合偶然移动的 AWG 22/7 柔性电缆 AWG 22 软电缆,用于连续移动,例如电缆护套或机械手 Technical Specifications Order number 6XV1840-2AH10 6XV1841-2A 6XV1870-2B 6XV1841-2B Product type designation IE FC TP Standard Cable GP 2 x 2 (Type A) IE FC TP Robust Standard Cable GP 2 x 2 (Type A) IE FC TP Flexible Cable GP 2 x 2 (Type B) IE FC TP Robust Flexible Cable GP 2 x 2 (Type B) Product description Standard bus cable (4-core), sold by the meter, unassembled Standard bus cable (4-core), sold by the meter, unassembled Flexible bus cable (4-core), sold by the meter, unassembled Flexible bus cable (4-core), sold by the meter, unassembled Suitability for use Standard cable with rigid cores for fast installation Standard cable with rigid cores for fast installation For occasionally moved machine parts For occasionally moved machine parts Cable designation 2YY (ST) CY 2x2x0,64/1,5-100 GN SF/UTP 2YH (ST) C99Y 2x2x0,64/1,5-100 GN SF/UTP 2YY (ST) CY 2x2x0,75/1,5-100 LI GN SF/UTP 2YH (ST) C99Y 2x2x0,75/1,5-100 LI GN SF/UTP Electrical data 西门子总线电缆 Damping ratio per length ● at 10 MHz maximum 52 dB/km 65 dB/km 60 dB/km 65 dB/km ● at 100 MHz maximum 195 dB/km 220 dB/km 210 dB/km 220 dB/km Impedance ● at 1 MHz ... 100 MHz 100 ? 100 ? 100 ? 100 ?
