Hello Everybody,
Richard Erlacher said Could you clarify how you apply the relay, please? If it is driven by a switch, then you could probably omit the relay, too, again, provided it doesn't violate some regulatory restriction. It's possible you might need either the relay or the optoisolator because you must be isolated from the signal source, but you probably don't need both, as either one provides isolation. Thanks Richard, 1.There are 10 IR remote control handsets in 10 different rooms numbered 1 to 10. 2.Each of these 10 rooms have wall mounted receivers suitable for above handsets. 3.Each of these 10 receivers,when activated by a key press in the handset,toggles the relay inside the receiver. 4.Each of these 10 receiver-relay's contact points (two in numbers) are in turn taken out of the rooms to be connected to a remotely located central-detector. 5.This central-detector has to detect which all room's remote receiver has been activated and naturally take programmed actions. Kindly let me know if the picture is clearer. With best regards A.S.Rudra |
