Hi, I'm re-designing a yet-to-be-implemented home remote control
lighting system that uses mechanical latching bistable (or impulse)
relays. These particular relays will change state with a low voltage
pulse on only 1 input pin.
I would like to convert the system to use SSR's but I'm uncertain
which to choose and how to achieve the one-wire bi-stable control. I
prefer SSR's for the higher operation count. A single relay will
drive a resistive load at most
of 2.5A 120V AC. The control voltage can be anything below 24V AC or
DC. I don't care about the retain-state-even-thru-a-power-outage
feature offered by the mechanical relays. I'm using simple momentary
contact pushbuttons for controls with no debouncing.
questions:
1) Do any SSR's exist that already contain some or all of the extra
features I need? (debouncing, bi-stable, one-wire control)? I'd like
to keep it cheap --at most $25 per relay.
2) The question #1 is no, can you point me to some simple SSR support
circuits that would work?
