Ask me a question about Solid State Relays?

Former Member

When to use Solid State Relays vs. Electromechnical Relays?

If faster switching response, no bounce, silent operation and long life are required.

    Hi Aiman,

    I am working on project to control a temperature of a coolant system so basically I am using PID temperature controller to drive 2 solid state relay to switch my loads on/off, the SSR drive in my PID controller Max current rate is 20mA, let assume that the 2 SSR required more current, could you help me to find external SSR Driver circuit that boost the current from my SSR driver in my PID controller  and this external SSR drive will drive my 2 SSR ( like if you give me a product name so I could purchase it) waiting for your reply with many thanks.
