Customizable Relay Board
with Latching Option & Active High/Low Options
This listing is for a fully assembled and tested customizable single channel relay driver board. Using only one header connector, you can choose the trigger to be active high, active low, or toggle. It requires 7-12 volts to operate. To trigger an operation, there is an input signal line labelled "SIG". This is TTL (5v) compatible. No more than 5v should be applied to this line. This makes it easy for you to interface with your Arduino, TTL project, Basic Stamp, ARM or PIC project. It comes sealed in an ESD bag, with a single header connector. Please watch the video above for a demonstration. We also sell these in DIY kit form for a few dollars less. There is an assembly demonstration video below that also offers another test demonstration. The below information talks about the different operations you can choose from. You can not make changes on the fly. When you power up, depending on how you have your header connected will determine your mode of operation until you power off and on again. The colour of the relay may vary. It may be blue or green. Just an FYI =) Control your low power AC devices, or DC actuators today!
Operation Option#1 (ACTIVE-LOW)
If you place your header connector on the header marked "LOW", then the relay will be ON when there is 0v at the SIG (Signal) input, and LOW when you place 5v on the SIG (Signal) input. This is the ACTIVE-LOW Option.
Operation Option#2 (ACTIVE-HIGH)
If you make no connections to either the "LOW" or "LAT" connectors, then you are in the default mode, which is ACTIVE-HIGH mode. When you place a 5v signal on the SIG line, the relay actives and will stay activated until the voltage at the SIG line goes low (0v).
Operation Option#3 (LATCHING MODE - The Coolest Mode!)
If you place your header connector on the "LAT" header (Stands for "latching"), then every time the device receives a pulse at the SIG line, the output will toggle. When you first power up the device, the relay is off. After a single pulse is pulsed to the SIG line, the relay turns on and stays on until another pulse triggers the relay to toggle off. This is my favourite mode, and I think that it is likely the most useful mode. Please watch the videos for a demonstration.
Requirements:
1) 7-12VDC for power.
2) Signal Input "SIG" is rated for digital 0-5v signals.
Pinout:
1) V+ = Positive Power Supply Pin
2) SIG = Signal Input
3) GND = DC Ground
4) NC = Normally Connected To Common Relay Pin (Normally Closed)
5) CO = Common Pin
6) NO = Normally Unconnected To Common (Normally Open)
WARNING:
If you are going to be connecting 120VAC or higher to the relay, and you don't know what you're doing, make sure that someone is with you who can offer you some safety tips. high voltage can kill you easily, and I won't be held responsible if you hurt yourself. You have been warned =)
