This kit is our kits 3079A, 3079B and 3079C all supplied in one box. Each kit is supplied complete with all components and separate PCBs. Ideal for education use.
Each circuit is a simple well tried design. One uses two transistors in a super-Darlington set-up. The second uses the LM741 op-amp, and the third uses a Schmidt trigger design.
Each board has a PCB-mounted switch to convert the circuit from light to dark switching and vice versa. All board have an SPDT relay output rated to switch resistive loads of up to 5 Amps @ 240Vac or 28Vdc max.
