Solid State Relay Selection

2008-02-28View Original

Thread Content

I am currently working on a small alarm project and need to elicit an output signal in our on-site DCS system. However, our output module output is a logic signal (5-12V), so we need a solid-state J relay to convert it and drive the alarm buzzer. The maximum output current of the logic signal is 100mA. It is controlled by a 5V power supply on site. The buzzer is a 110V power supply with a 20 mA conduction. Can anyone recommend me several types of solid-state relays? Thank you.
