Cindest Posted August 3, 2023 Share Posted August 3, 2023 Since the output current is only 2.5 mA, I connected a boost circuit (Adafruit Boost 1000) which loads the output. I also tried a Boost 2 Click which loads the output. I need to supply 4 V and 9 mA to a SSR. What kind of boost will work? Link to comment Share on other sites More sharing options...
0 Fausto Posted August 3, 2023 Share Posted August 3, 2023 Hello @Cindest. The digital output current is 2.5 mA on the USB-3101 device. https://www.mccdaq.com/pdfs/manuals/USB-3101.pdf What are the requirements of the Adafruit devices? Do you have their datasheets to determine if their output will work with the SSR? Regards, Fausto Link to comment Share on other sites More sharing options...
0 Cindest Posted August 3, 2023 Author Share Posted August 3, 2023 The PowerBoost 1000 Basic states that it can boost 1.8 V with a TPS610 boost converter. The quiescent current of the powerBoost is 5 mA. The output is listed as 5.2 V. The SSR needs 4 V at 9 mA. The Boost 2 Click from Mikroe boosted the voltage, but the relay chattered. I tried the PowerBoost 1000 to solve that problem and it won't turn the relay on. I would appreciate any help you have. Link to comment Share on other sites More sharing options...
