I want to be able to turn something on and off from several locations. This is an ideal board for that purpose. It uses the dedicated HR810 for that pushbutton switching. Board has wide operating voltage up to 24V and I assume as most that includes 24V battery systems that would normally run at 27V-29V. The relay used in this device is 5V and it is run from a linear regulator. That relay takes 70ma when on which could be a big battery drain on some systems. It also means a lot of heat will be created at high voltages. At 24V the board temperature got to 48C operating at 14V. When voltage increased to 27V the board was over 86C, getting near boiling. This can easily be corrected by dissipating some of that heat in an external resistor. This IC can operate at this temperature, experience has just taught me that extended life will happen at lower temperatures. Just assume the board needs 10V to operate. For every volt above that add an additional 10 to 15 ohms. For lowest board heat that would be 33 ohms 1/2W for a 14V supply and 200 ohms 1W for 28V.The board works well with the trigger input switching to common. That input is powered from +5V and it suitable for sensors with an open collector NPN output.

The circuit is designed to “feel” like a latching relay, but it is a standard relay that toggles on or off but must be continuously powered or, like any SPD-xxVDC-SL-C relay, the state will not be maintained. This means if you are building a low-power system, you’ll need to burn battery to continuously energize the coil in the relay to maintain a non-normal state. There are true latching relays that, once set, remain in that state: Adafruit has a nice one, but this is not one.

This is a simple Bistable* Filp-Flop Module, with a Cube Relay for the Output. *Bistable means two 'stable' states: one is [ the RELAY is ON ] and the other is [ the RELAY is OFF ].TO USE: Connect the [V] Terminal to +24VDC, and the [G] Terminal to (Zero Volts/Ground/24VDC "Return"). Whenever the [T] / "Trigger" Terminal is connected to ( Zero Volts/Ground/24VDC "Return" ), the OUTPUT WILL CHANGE STATE ( Toggle from OFF to ON to OFF to ON and so on, each time a new connection to [G] is made ).When the Relay is not energized, the module draws 4 mA ( 0.004 Amps ) at 24VDC. When the Relay IS Energized, the module draws 68 mA ( 0.068 Amps ) at 24VDC. When 24VDC power is first applied, the Relay is OFF. The Circuit Board says: "DC 5 - 24V". I have only used it at 24VDC and it seems fine.The Circuit Board appears to be well made. The "Cube" Relay is stamped with the [ The “Recognized Component Mark” ] issued by Underwriters Laboratories (UL). This mark is placed on components that are intended to be part of a UL listed product, but which cannot receive the full UL logo themselves. That is because the UL Mark can Only be given to the entire 'Product', not just to one of the components.The Relay Contacts are Rated [ 10Amps at 250VAC and 10Amps at 30VDC ], but it is quite small. I would NOT use it at 10Amps and expect a 'Long Life'. I would keep it under 2Amps, Max, to be safe. - Don -

Wanted to use a momentary push button to turn some 12v lights on and off. I didn't have all the components on hand to build my own flip-flop. So I searched Amazon and sure enough, I found a pre-made one I could get the next day. It works great and is holding up well in its abusive environment.
