系统接地方式有:浮地方式、直接接地方式和电容接地三种方式。对PLC控制系统而言,它属高速低电平控制装置,应采用直接接地方式。由于信号电缆分布电容和输入装置滤波等的影响,装置之间的信号交换频率一般都低于1MHz,所以PLC控制系统接地线采用一点接地和串联一点接地方式。集中布置的PLC系统适于并联一点接地方式,各装置的柜体中心接地点以单独的接地线引向接地极。如果装置间距较大,应采用串联一点接地方式。用一根大截面铜母线(或绝缘电缆)连接各装置的柜体中心接地点,然后将接地母线直接连接接地极。接地线采用截面大于22 mm2的铜导线,总母线使用截面大于60mm2的铜排。接地极的接地电阻小于2Ω,接地极最好埋在距建筑物10 ~ 15m远处(或与控制器间不大于50m),而且PLC系统接地点必须与强电设备接地点相距10m以上。
信号源接地时,屏蔽层应在信号侧接地;不接地时,应在PLC侧接地;信号线中间有接头时,屏蔽层应牢固连接并进行绝缘处理,一定要避免多点接地;多个测点信号的屏蔽双绞线与多芯对绞总屏电缆连接时,各屏蔽层应相互连接好,并经绝缘处理。选择适当的接地处单点接点。 NUMATICS 24VDC 4.0W 14.5-232 PSIG-AIR SOLENOID VALVE, I22BB500R061D61 NUMATICS NPTF 150 PSIG-AIR PNEUMATIC SOLENOID VALVE, I23BB500MP14X61 NIB NUMATICS 120V .24A 280 PSIG-AIR SOLENOID VALVE W/ BASE, I35SS73BK BAILEY BABCOCK & WILCOX PNEUMATIC FUNCTION GENERATOR FG111 NUMATICS 150PSIG SOLENOID VALVE NNB I35SS43BK000030 101800 VICKERS VANE TYPE HYDRAULIC PUMP 4535V 60A 35 KYOHO56H40026 HCI-XD CYLINDER 40MM BORE 910MM STROKE 40X910-LB YUKEN HYDRAULIC CYLINDER CJT70-FA 80C 65H-ABD NUMATICS SOLENOID 225-372B, 24VDC 6.0 WATTS 26AMP, 150PDIG- AIR NNB NUMATICS 123SS515K 120 VOLTS 50/60 HERTZ 150 PSIG DOUBLE SOLENOID VALVE STAFSJO KNIFE GATE VALVE W/ PNEUMATIC ACTUATOR AC-160 102573 CAT PUMPS GENUINE PARTS CONNECTION ROD 121467 NIB NUMATICS 120V .12A 150 PSIG-AIR SOLENOID VALVE W/ BASE, 082SA415K ENIDINE HYDRAULIC SHOCK ABSORBER MT 206313 NIB MONITEUR * SENTINEL PNEUMATIC VALVE WITH PARTS * AMYB-5120 FESTO LINEAR CYLINDER DZH-50-100-PPV-?A SMC 32MM BORE 30MM STROKE 0.7MPA PRECISION CYLINDER, MTS32-W2316-30 BIMBA SS PNEUMATIC CYLINDER 094-NRP FESTO PNEUMATIC STANDARD CYLINDER DNG-100-25-PPV-?A NNB SCHROEDER FILTER KW NIB SMC PRESISION AIR PRESSURE REGULATOR AR20-01B FESTO DZH-40-PPV-A CYLINDER REPLACEMENT PARTS NIB WHITEY 200PSI SPRING RETURN W/ VALVE 133 SR MAC AIR VALVE 56C-52-RA *MANUFACTURER REFURBISHED* FESTO 63MM BORE 725MM STROKE PNEUMATIC CYLINDER, DGP-63-725-PPV-?A-B BIMBA BF-091-R SQUARE HEAD PNEUMATIC CYLINDER, NNB DE-STA-CO 82P35 CLAMP 82P35- 5400000-NPT 105491 VEKTEK RIGHT HAND, 5000 LB CAPACITY SINGLE ACTION SWING CLAMP 15-0118-00 RH NUMATICS 120V, 50-60HZ, 0.11 AMPS SOLENOID VALVE 153SA43AK KYOHO MACHINE WORKS HCI-XD HYDRAULIC CYLINDER 50X108-CB / 66H50887 NUMATICS SOLENOID VALVE 24 VDC 6.3 WATTS 225-285B AEROQUIP 2681-24 SINGLE WIRE BRAID HI-IMPULSE LOW PRESSURE HOSE, NNB HYDRAULIC THREAD NUT HMV120 SMC CDLABN80-K5242-?XC11 (80+60) BIMBA 25MM BORE 50MM STROKE PNEUMATIC CYLINDER E-25-50-U PARKER FLANGE FITTING P11571-20-20 SAE CODE 61 FLANGE STRAIGHT SERIES 71 SMC PNEUMATIC AIR ACTUATOR MGPM63-75-Z73L-?XC35 NUMATICS 124BA415MP00061 24 VDC 150 PSIG PNEUMATIC VALVE COMPACT PNEUMATIC CYLINDER QJ93-2096 JAMESBURY PNEUMATIC VALVE ACTUATOR ST-1200 W/ POSITIONER 103495 NUMATICS 120V .37A 50/60HZ 150 PSIG-AIR PNEUMATIC SOLENOID VALVE, 555SA43AK PHD INC.
