KC868-A16 to steer a 24V AC circuits - dobrogi - 11-17-2024 Hi I want to control 24V AC devices with KC868-A16 (irrigation valves). At first I thought I could use kc868-a16 outputs to directly steer the devices but it doesn't work for AC. So I thought I could make use of 16 channel relay module like the one below but it's controlled by 5V low-level inputs. How can I use A16 with the relay? What other devices do I need to make it work? RE: KC868-A16 to steer a 24V AC circuits - admin - 11-18-2024 why not chose a 12v extend relay board? it's commonly used in market. not chose 5v level version. RE: KC868-A16 to steer a 24V AC circuits - dobrogi - 11-18-2024 Hi, thank you for your answer. 1. Unfortunately it doesn't bring me closer to the solution of the problem how to use the devices I own. 2. 99% of 16 channels relay modules on the market are the one I mentioned in the first post. There are 2 types of working voltage 5V and 12V but both types have low-level steering inputs. I know, the best would be to use Kincony's KC868-E16 but it's 20x more expensive. RE: KC868-A16 to steer a 24V AC circuits - admin - 11-18-2024 if you want to use your own 5v extend relay board. you need add a level convert circuit. convert 5v -- 12v level. RE: KC868-A16 to steer a 24V AC circuits - dobrogi - 11-18-2024 I will probably use 2x 8 channel PC817 Optocoupler to control 5V circuits with 12V. RE: KC868-A16 to steer a 24V AC circuits - admin - 11-18-2024 it's ok, add a Optocoupler for convert.
