SPFEC12 ABB 人工智能模块
【产品详情】
制造商:ABB
产品编号:SPFEC12
ABB型号名称:-
目录描述:人工智能模块，15通道，支持4-20mA，1-5V
SPFEC12是ABB Bailey Infi 90的ABB Symphony Plus版本IMFEC12 目录说明：AI模块，15通道，支持4-20mA，1-5V
备用部件号：IMFEC12，YSPFEC12，RSPFEC12，PSPFEC12，SPFEC12-REP
SPFEC12利用PLC控制电机正反转等正、反动作时，为避免PC的异常动作引起事故及机械损坏，应在外部组成一个连锁回路。接地：GR端子是大地接地端子。用防止感应电的专用接地线（截面积2mm2以上的电线）采用第三种接地方式（接地电阻100Ω以下）。LG是噪音滤波器中性端子，若因噪音大而产生误动作，或为了防止电击，把LG与GR短接，采用第三种接地方式。接地线的长度在20m以内为宜。接地线与其它设备共用或与建筑物的金属结构连接会适得其反，受到恶劣影响。 对于PLC输出不能直接带动负载的情况下，必须在外部采用驱动电路，可以用固态继电器或晶闸管电路驱动，同时应采用保护电路和浪涌吸收电路。

【英文介绍】
Manufacturer :ABB
Product number :SPFEC12
ABB model name :-
Description: Artificial Intelligence module, 15 channels, support 4-20mA, 1-5V
SPFEC12 is the ABB Symphony Plus version of ABB Bailey Infi 90 IMFEC12 Directory Description: AI module, 15 channels, 4-20mA, 1-5V
Standby component number: IMFEC12, YSPFEC12, RSPFEC12, PSPFEC12, SPFEC12-REP
When the SPFEC12 uses PLC to control the positive and negative action of the motor, in order to avoid accidents and mechanical damage caused by the abnormal action of the PC, a chain circuit should be formed outside. Ground: The GR terminal is a ground terminal. Use a special ground wire (wire with a cross-sectional area of more than 2mm2) to prevent induced electricity. Use the third ground method (ground resistance less than 100Ω). LG is the neutral terminal of the noise filter. If misoperation occurs due to loud noise or to prevent electric shock, short-circuit the LG and GR and use the third grounding method. The length of the ground cable should be less than 20 Mbit/s. Ground wires shared with other equipment or connected to the metal structure of the building will backfire and be adversely affected. In the case that the PLC output cannot directly drive the load, a drive circuit must be used externally, which can be driven by a solid-state relay or thyristor circuit, and a protection circuit and a surge absorption circuit should be used.
