1785BEM PLC输入回路的设计 1．电源回路 PLC供电电源一般为 AC85—240V(也有DC24V)，适应电源范围较宽，但为了抗干扰，应加装电源净化元件(如电源滤波器、1：1隔离变压器等)。 2．PLC上DC24V电源的使用，各公司 PLC产品上一般都有DC24V电源，但该电源容量小，为几十毫安至几百毫安，用其带负载时要注意容量，同时作好防短路措施(因为该电源的过载或短路都将影响PLC的运行)。 3. 外部DC24V电源 若输入回路有 DC24V供电的接近开关、光电开关等，而PLC上DC24V电源容量不够时，要从外部提供DC24V电源；但该电源的“—”端不要与 PLC的 DC24V的“—”端以及“COM”端相连，否则会影响PLC的运行。 PC-0984-685 MODICON Modicon PC-A984-141 MODICON PC-A984-145 Modicon CPU PC-E984-251 Modicon PC-A984-141 CPU MODICON PC-0984-380 AS-9507-000 MODICON PC-0984-385 MODICON PC-A984-130 Modicon PC-A984-145 Modicon PC-M984-230 Modicon CPU PC-E984-245 MODICON PC-E984-685 Modicon PC-E984-685 PC-0984-480 MODICON PC-A984-145 MODICON Modicon PC-E984-480 Modicon PC-L984-785 PC-0984-380 MODICON PC-0984-485 MODICON PC-0984-385 MODICON Modicon PC-E984-385 MODICON PC-E984-685 PC-A984-130 MODICON Modicon PC-E984-685 BAUSCH 33-45-58 PC-E984-258 Modicon MODICON PC-0984-685 PC-E984-275 Modicon Modicon PC-E984-485 PC-A984-131 Modicon Modicon PC-A984-141 MODICON 100-021 Modicon AEG PC-E984-785 PC-E984-258 Modicon Modicon PC-K984-785 Modicon PC-A984-130 Modicon CPU PC-E984-785 PC-0984-780 MODICON Modicon PC-0984-455 MODICON PC-0984-485 Modicon PC-E984-265 MODICON PC-A984-141 MODICON PC-A984-130 PC-E984-265 Modicon MODICON PC-0085-103 Modicon PC-E984-275 PC-A984-145 Modicon Modicon PC-A984-145 Modicon PC-0984-455 Modicon PC-E984-685 MODICON AS-516P-002 MODICON 100-456 PC PC-E984-245 Modicon Modicon PC-E984-251 MODICON PC-0984-680 MODICON PC-E984-385 MODICON PC-E984-785 Modicon PC-0984-385 PCE984785 Modicon 1785ME32 Modicon PC-E984-785 Modicon PC-0984-120 MODICON PC-A984-145 MODICON PC-A984-145 MODICON PC-E984-685 Modicon PC-0984-685 PC-0984-381 MODICON Modicon PC-E984-685 Modicon PC-0984-381 MODICON PC-A984-145 MODICON PC-0984-480 MODICON PC-0984-381 MODICON PC-0984-455 MODICON AEG 984-785E Modicon PC-A984-245 PC-A984-131 Modicon Modicon PC-A984-145 Modicon PC-0984-455 Modicon CPU PC-O984-480 Modicon PC-E984-251 1785ME64 Modicon PC-E984-258 Modicon PC-E984-381 Modicon PC-E984-785 MODICON PC-A984-130 Modicon PC-0984-455 MODICON AS-212P-020 Modicon PC-0984-381 Modicon PC-0984-381 Modicon PC-0984-680 MODICON PC-A984-145 Modicon PC-0984-381 PC-A984-120 Modicon Modicon PC-M984-230 AM-SA85-000 MODICON Modicon CPU PC-O984-680 Modicon PC-0984-380 PC-0984-380 Modicon PLC Modicon PC-L984-785 Modicon PC-A984-130 MODICON PC-O984-685 CPU Modicon PC-K984-785 MODICON PC0984-381 MODICON AS-9584-000 Modicon PC-A984-145 MODICON PC-0984-785 PC-A984-120 MODICON Modicon PC-A984-145 CPU PC-0984-455 MODICON MODICON PC-0984-485 CPU PC-A984-145 MODICON PC-0984-485 MODICON MODICON PC-M984-230 MODICON PC-A984-141 Modicon PC-A984-145 Modicon PC-E984-785 MODICON PC-A984-130 Modicon PC-L984-785 Modicon BBC-43C Modicon PC-0984-145 CPU MODICON PC-E984-245 Modicon BCC-47 MODICON PC-A984-145 Modicon PC-0984-385 MODICON PC-A984-145 MODICON PC-E984-285 MODICON PC-A984-120 CPU MODICON PC-A984-130 CPU Modicon PC-E984-680 1785KE MODICON PC-0984-385 MODICON PC-0984-381 Modicon PC-0984-780 MODICON PC-0984-381 MODICON AS-P120-000 MODICON PC-0085-103 Modicon AEG PC-0984-145 CPU Modicon PC-A984-130 1785KA Modicon PC-0984-381 Modicon PC-F984-785 Modicon PC-E984-275 MODICON PC-A984-120 CPU MODICON PC-E984-685 MODICON PC-A984-145 Modicon AS-S954-100 MODICON PC-0984-130 MODICON PC-0085-102 MODICON PC-E984-241 1785L11B​ MODICON PC-F984-685 MODICON PC-0984-145 MODICON PC-0085-101 MODICON PC-A984-120 Modicon PCB M907-100 MODICON PC-0085-103 MODICON PC-0984-351 MODICON PC-0984-381 MODICON PC-0984-485 MODICON PC-0984-480 MODICON PC-0984-120 Modbus PC-A984-145 MODICON PC-CBCA-000 Modicon PC-0984-485 MODICON PC-M984-230 MODICON PC-A984-120 MODICON PC-A984-131 1785BEM
