Hi alect_t,
OK, it is not that easy to follow the circuit of this remote. Everything is connected to a IC (unknown for me).
On top of this, there are buttons on the remote which switch ON/OFF all the 4 channels, and these buttons have the oposite polarity, e.g. the common wire is (-) and the ON and OFF wires are (+), while the other 4 channels are as described before - common (+), ON/OFF wires - (-).
So I have decided to use a low current reed IC relays (very fast, almost totaly silent, etc.). Thus the module I am building here will be more universal and I will be able to use it for other purposes/drives, etc. For instance I am going to use another remote controlling not RF Sockets, but RF wall switches.
So I've connected the two relays to the NPN transistors and your circiut works perfectly.
BUT, when I press the button (this button is only to test), the ON line and ON relay are producing maybe 10 very fast switching when the time of the signal overs. The OFF relay works perfect - it never produces more than 1 switching. This behaviour is the same also if no relays (the LED is kind of bliking very fast for a short period at the end of the signal).
How to solve this? Is it something related with the hysteresis effect? Do we have hysteresis effect with HEX TRIGGER at all?
Maybe I didn't connect something properly, or how to check this? BTW, the issue is only seen after 1-2 cycles, i.e. after several seconds of idle, the 1st trigger is always good.
Thanks for your time and apologies for the delay but I was away from home these days.
