![]() ![]() Overall this ON delay relay circuit is a good value for the money. I ended up putting this circuit into a small plastic box and brought the wires in through little holes to prevent them from moving. Size: 45mm x 100mm x 130mm (1.8 x 4 x 5) Weight: 200g (7 oz) Standard Connector: Deans. Range: The unit can measure any Lipo pack of 2 6 cells in the range of 500mAh 6000mAh. For a completely stationary application, this might not be a problem, but if the attached wires are moved at all, there is a chance that they will come loose, even if the terminal screws are tightened fully. Protection: Unit is protected against reverse polarity on both main power and search wire inputs. My only quibble with the quality of this device is the weakness of the external wire terminals to hold on to a wire under a fairly small amount of pulling force. The actual delay period is more like 40-50 seconds maximum, but it can be adjusted down to zero with the turn of a small potentiometer. ![]() The pair of LED's is a nice touch to indicate when power is applied to the device and then when the relay is energized after the delay period. Again, for the expert technician, these things could be dismissed, but the novice might be left confused. The video demonstration was fairly clear, but it contained extraneous wires leading to unknown devices off-screen. No instructions arrived with the shipment. For an experienced electronics person, this was made clear by the video, but for some who might be able to use this device but are less technically oriented, the description and video could have been a lot clearer. This little circuit should have been titled an "ON Delay relay" circuit.
