KL2808 | HD Bus Terminal, 8-channel digital output 24 V DC
The KL2808 digital output terminal connects the binary control **s from the automation device on to the actuators at the process level with electrical isolation. The KL2808 is protected against polarity reversal and processes load currents with outputs protected against overload and short-circuit. The Bus Terminal contains eight channels, consisting of a ** output and 0 V DC. The ** states are displayed by LEDs. The power contacts are looped through.
The outputs are fed via the 24 V power contact in the KL2808. The conductors can be connected without tools in the case of solid wires using a direct plug-in technique.
The HD Bus Terminals (High Density) with increased packing density feature 16 connection points in the housing of a 12 mm terminal block.

注意，CX10xx 和 CX90xx 的区别不仅在于时钟主频，还在于 CX10xx 的 CPU 是 x86，而 CX90xx 的 CPU 是 ARM 芯片，没有浮点运算协处理器。所以只有在纯逻辑运算的项目中， 才推荐使用 CX90xx 系列。
