The CD4001BM, HEF4001BT, and MC14001D are NOR gates provide the system designer with direct implementation of the NOR function and supplement the existing family of CMOS gates. All inputs and outputs are buffered IC SOP-14 Pins Package.
The IRF540N is a 100V 30A To-220 Package Third generation power MOSFETs from Vishay provide the designer with the best combination of fast switching, ruggedized device design, low on-resistance and cost-effectiveness.
The low level triggers the relay module's power indicator (green) and the 4-way relay status indicator (red). User-friendly interface design, all interfaces can be directly connected through the terminal leads. Four fixing bolt holes are provided.
