Hi,
I wonder if there is any board that fits my needs...
I'm driving lights & blinds using 24VDC relays and all over the house I have buttons(lights) or up/down buttons(blinds). All this buttons have 24VDC and are connected to main junction box that has all this relays which drive 240VAC lights/blinds.
I want board that has single pin(so I need to connect just 1 wire, per light) that reads that wire 24V via optocoupler at same time board has on same pin MOSFET that can drive that relay.
So idea is, that I can detect when user is pressing some button and they drive lights, but at same time I can drive lights and in both cases I want to read this signals.
Does such board exist?
I already have KC868-A16 but as far as understand I need additional optocoupler, since I'm not allowed to connect 24VDC on input, so I need external optocoupler to simulate dry contact on KC868-A16 and makes everything ugly with additional optocoupler and 2 wires per relay.
Thanks,
David
