集电极开路
需要特别注意集电极开路电路(下图中的上半部分电路),使输入电 压能够产生足够大的源电流,因为它不仅受限于1756-HSC输入电 阻,还受限于集电极开路上拉电阻。
根据所选择的输入端子,会产生各种不同的选项,如下表所示。如果 我们假设D1 + Q1上的压降为2.0 V,则可以使用以下等式计算可用 电流:
(供电电压)-(Vdrop)
(上拉电阻)+ R1 (如果使用)+ (R2)=可用电流
示例 供电电压 输入端子 总阻抗 可用电流
1 12 12…24 V 3.15 kQ 3.1 mA (不足)
2 12 5 V 2.15 kQ 4.6 mA (低)
3 24 12…24 V 3.15 kQ 6.9 mA (佳)
4 24 5 V 2.15 kQ 10.2 mA (可接受)
您将供电电压增大到12 V以上, 以确保足够大白 输入电流来克服
额外的2kQ上拉阻抗。请牢记可用电流至少为4mA。
