XBTF032310
本产品的数字输入和输出可以连接正逻辑或负逻辑。
信号输入受到反极性保护，输出受到短路保护。输入和
输出功能隔离。
如果使用负逻辑，则信号的接地故障被检测为接通状态。
逻辑类型的选择
逻辑类型由DI\U COM和DQ\U COM的布线决定。逻辑类型影响接线和控制
传感器数量；因此，您必须在工程设计阶段根据
应用
特殊情况：安全功能STO
安全功能STO的输入（输入STO\u A和STO\u B）只能连接到正极逻辑。
逻辑类型激活状态
（1） 正逻辑输出提供电流（源输出）
电流流向输入端（接收器输入端）
（2） 负逻辑输出消耗电流（接收器输出）
输入电流（源输入）
警告
非预期设备操作
确认信号短路不会导致设备意外运行。
不遵守这些说明可能导致死亡、重伤或设备损坏。

The digital inputs and outputs of this product can be wired for positive logic or negative logic. Signal inputs are protected against reverse polarity, outputs are short-circuit protected. The inputs and outputs are functionally isolated. If negative logic is used, a ground fault of a signal is detected as an On state. Selection of the Logic Type The logic type is determined by the wiring of DI_COM and DQ_COM. The logic type affects wiring and control of the sensors; therefore, you must determine the required value in the engineering phase in view of the application. Special Case: Safety Function STO The inputs for the safety function STO (inputs STO_A and STO_B) can only be wired for positive logic. Logic type Active state (1) Positive logic Output supplies current (source output) Current flows to the input (sink input) (2) Negative logic Output draws current (sink output) Current flows from the input (source input) WARNING UNINTENDED EQUIPMENT OPERATION Verify that a short-circuit of a signal cannot cause unintended equipment operation. Failure to follow these instructions can result in death, serious injury, or equipment damage.
