Relay Sequencer Circuit at Jean Perrier blog

Relay Sequencer Circuit. So we are going to use a simple transistor to switch the relay connected to it. Discover how the single pole double throw (spdt) relay works with helpful wiring diagrams, videos, and applications. The circuit is powered by 12v ; This project describes how to build this sequencer. The end goal will be to design a circuit to perform relay or mosfet (have not decided yet) sequencing with some added features. This of course ensures your relays never actually switch rf. 60ms later, outputs regulated 5v for the ldmos bias; When 12 v is removed during tx, a relay in preamp2 will ground the input and protect the electronic circuit. Following the schematic posted below and build the circuit. This will require using a fair amount of circuit board. Immediately outputs 12v to close the t/r relays; I used two from radioshack. Closing the top switch causes the light bulb to turn on, and stays on when the top switch is opened. In this post, i’ll share the sequencer. Ic 555 is incapable of driving relay directly since the output current from a typical 555 ic is low.

This will require using a fair amount of circuit board. A relay sequencer is used in a radio transverter and is use to activate particular stages in order after short delay. I used two from radioshack. Closing the top switch causes the light bulb to turn on, and stays on when the top switch is opened. Immediately outputs 12v to close the t/r relays; Following the schematic posted below and build the circuit. 60ms later, outputs regulated 5v for the ldmos bias; The heart of the sequencer is the relay. Ic 555 is incapable of driving relay directly since the output current from a typical 555 ic is low. When 12 v is removed during tx, a relay in preamp2 will ground the input and protect the electronic circuit.
