Can some one who has use this in the past

Can any one tell what the values that would be used in the· Standard Circuit· the one ·in the data sheet

    Sam,

    What do you mean? Which circuit?

    @Sam, DigiKey lists 34 items for Sharp 8A solid state relays so you need to be a bit more specific to get an answer.

    PS - Have you received the two boards I sent back to you? They should have arrived a while back.

    Yes, I can help in like manner. The Standard Circuit always uses standard values as per the datasheet. If that doesn't work just try the standard thing.

    See, no problems. roll.gif

    The one that Parallax sell

    In the Data sheet dose not give any values on the circuit I do not know ·what to use· Standard Circuit·

    Sam,

    Isn't it a courtesy to at least give a link to the product or be a bit more descriptive? I mean, you have taken the time to ask the question and others take the time to answer or at least read it.
    Do you want each of us to hunt and guess as well?

    Sam,

    Forget the standard circuit, its for Micros that can't source 20mA. Its just an IR LED inside the module (pins 3 and 4)

    If you're using a prop, connect the prop output pin to one side of a 100 ohm resistor (for 20mA through the LED, whose forward voltage is about 1.3v), and other side of the resistor to pin 3 of the sharp module. Connect pin 4 to ground / Vss.

    Agree with others though, more info and/or links up front would get you a much quicker response!

    cheers

    FYI what Tubular says applies to most (but not all) SSR's regardless of their output voltage and current ratings. they are IR leds on the input and a series resistor of 100 ohms for 3.3V or 180 ohms for 5V operation is all that is required as long as the micro or other circuit can provide 20mA. You also do not need a snubber circuit on the output for resistive loads with 60Hz.

    I have a 240V 50A three phase SSR from Crydom that is controlled directly from a prop pin through a 100 ohm resistor.

    Thank You for your reply

    I have used Optic sensor before but not this type of SSR

    So when it show part symbol with·NO value then I have·NO··idea.gif·how to use it



    You also do not need a snubber circuit on the output for resistive loads with 60Hz.

    Is a snubber circuit used when you are using a Motor with a SSR

    I want to thank every one who reply to this post

    A snubber is used with a motor and other inductive loads to keep the SSR from being turned on by fast voltage spikes.
