Where can I obtain an owners manual, spec sheet, etc on the Audio TPA3116 Mini Power Amplifier which I just received, purchased from Amazon.com. It arrived nicely packaged, but absolutely no literature with it other than a business card Droking.com.

Please send programing /calibration/ operator manual for 4-20 ma signal generator . I want to have display 0-100.0 count with 4-20 ma output. How do I use the two buttons in the inside to set the generator?

is it possible to get these images again?

i want to add the on/off switch as well

Hello Ed Quittkat,
Thank you for writing in.
Do you mean you want to use a switch to control the power supply for this module on/off?
If yes,there is a solder joint place for controlling power on/off.
You can try to remove D2 diode and install it to D1. Then use leading wire to transfer the positive pole of D2 the position of Power on/off and shorted the botton part of the solder joint place of Power On/off.
Here are some images for referrence:






Hope this can help you.
If there is any question, please feel free to contact us.
Best regards

I was running an online real estate agency, but requests were rare: the website was clunky, social media was empty, and the CRM was manual. I was considering going back to offline until I saw a review about https://fntmanagement.com/services/ . We got branding, digital ads, workflow automation, and calendar integration. Property viewings increased, transactions doubled, and the team is working efficiently. My business in Quebec has flourished thanks to their approach.
