DS200TCCBG3BED 微处理器和多个PROM模块

GE I/O TC2000模拟板DS200TCCBG3BED具有一个80196微处理器和多个PROM模块。它还包含一个LED和2个50针连接器。从单板侧面可以看到LED。50针连接器的id为JCC和JDD。电路板上还有5个34针连接器。有一些指导方针要遵循，因为多个带状电缆可能连接到板。在断开带状电缆之前，请注意它们是如何在驱动柜内部布线的。电缆布线很重要，因为将信号电缆布线在电力电缆附近可能会对信号产生干扰。信号电缆的布放应远离电源线，并尽量减少两根电缆并联的走线长度。如果电源电缆和信号电缆交叉成90度角，则干扰最小。如果电路板上有光纤电缆，应确保它们不受干扰，可以靠近电力电缆。

检查旧板中的电缆路由的另一个原因是电缆可以阻止空气流动，这对于保持驱动器和所有组件冷却很重要。包括电机在内的运动部件在运行时产生热量。电子元件也会产生热量。如果布放不当，带状电缆会阻碍关键发热部件上方的气流。因此，在安装新单板时，请检查线缆的走线路径，并使用相同的走线路径。

The GE I/O TC2000 Analog Board DS200TCCBG3BED features one 80196 microprocessor and multiple PROM modules. It also contains one LED and 2 50-pin connectors. The LED is visible from the side view of the board. The IDs for the 50-pin connectors are JCC and JDD. There are also 5 34-pin connectors on the board. There are some guidelines to follow because of the multiple ribbon cables potentially connected to the board. Before you disconnect the ribbon cables, notice how they are routed in the interior of the drive cabinet. Cable routing is important because having signal cables routed near power cables can introduce interference to the signals. The best practice is to route signal cables far from power cables and to minimize the length of the run that the two cables are in parallel. If the power cables and the signal cables cross at 90 degree angle the interference is minimized. If the board contains fibre optic cables you should know that they are not subject to interference and can be near power cables.

Another reason to examine the cable routing in the old board is that cables can block air flow which is important for keeping the drive and all components cool. The moving parts, including the motor, generate heat while in operation. The electrical components also generate heat. The ribbon cable if not properly routed can block the air flow over the critical heat generating components. For these reasons examine the cable routing and use the same routing when you install the replacement board.
