Normally Closed AC SSR
This is a Normally Closed PCB Mount SSR. That means when DC Control input is low, the triac is ON, the output passes the load current to turn on small heater-motor-lamp or a bigger...

This is an Application note i used to give with my ssr – app012.pdf Diagram of SSR 5000 DC 3-30 Control / 230V AC N.O. @ 3A.
2N2646 based Voltage controlled SCR Pulser
A Center tap 50Hz Step Down Transformer with two diodes is used to get a train of Positive Sine Pulses at 100Hz which is applied to Q6 base via R51. 2N2646 is a unijunction...
AC-AC SSR Solid State Relay
This is a AC Control Input AC Output SSR Solid State Relay. When a Process Controller has an AC output or a system generates an AC signal of above 100V AC to signal the...
Drive SCR thyristor with 555
This circuit gives a burst of pulses to fire 2 SCRs, when pin 4 is taken to 12V the SCR is turned on, to use this circuit you need 12V short pulses phase shifted...
Solid State Relay – Common
This is a DC controlled Solid State Relay which can turn 230V AC equipment on and off. The output is like a NO normally open contacts of a relay and have to be in...
Triac based Lamp Dimmer power control
This is a phase angle control of a Triac which is a evolution from an SCR. The 50 Hz or 60 Hz Sine wave of mains can be turned on at any point after...
