ZK-TD4 is a MOS Switch Controller Trigger Delay Module with Timer and Cycle functions.It can work in 16kind work mode with or without trigger signal.It also can be delay a random time in the set range.
Neat find. I've never seen that module before. I'm thinking though that the "random" timing only applies to the DELAY mode or what they call mode P15... a random delay between 0 and 99 sec. That is, I don't think you can use the "random" capability in the cycle mode where it would be a random on-time (between 0-99sec) followed by a random off-time (between 0-99sec), repeating forever.
I suppose there might be some way to pair TWO of these modules, both set to random delay mode and triggering each other with one delay corresponding to the random on time, the other delay corresponding to the random off time.
