1. A self-latching circuit is designed to use a push-button to activate the power to the load. When the button is pushed the power supplied to the load and to the relay. Relay shorts terminals 30 and 87 allowing for continuous power to flow to the current even if the button is released (self-latching). When the timeout expires timer shuts the power to the relay which disconnects the power to the timer. This circuit consumes no power during the off state. Great for battery-powered applications. The timer is set to Function #2 and Trigger #1 (disabled).
2. Self-latching circuit is designed to use a push-button to activate the power to the load. Power is constantly supplied to the timer. When the button is pushed trigger wire connected to the ground and starts the On Delay function supplying the power to the output for a period of time. When the timeout expires timer shuts the power off. The timer is set to Function #2 and Trigger #4.
The trigger can also be changed to be connected to +12v instead of the Ground. In that case, change the trigger programming to #2.
3. Another version of the Self-latching circuit with control from an external source like vehicle ignition wire. The timer is set to Function #13 and Trigger #1. The circuit consumes no power during the off state. If a small standby current is not a problem then remove the relay.
4. Time Off Delay Self latching circuit with zero current consumption during off state. The timer is set to Function #12 and Trigger #2.
6. Function #21. Single Shot Time Reset and Hold on Trigger. One of the applications is to create light control where a button is used to activate the light. The light will stay on until the set time expires. Push of the button while the light is on will reset the timeout. Holding the button will either reset time out (if not expired) or will keep the light on until the button is released.
7. The timer might be used to boost the output of another signal or control wire. The output of the timer will mimic the logical state of the trigger wire. The output can also be changed to provide the output opposite of the control signal.
8. The timer might be used to create a button interface. For example, the configuration can be used to add light control to the truck bed. When the button is pushed timer supplies power to the output for a preset time and then shuts off. A secondary push of the button will turn the output off. The timeout can also be set to indefinite. Function #23 and #24.
9. If you need to change polarity to the motor you can use the circuit as shown below. Let's says you need for the motor to rotate one direction when the trigger is applied for t1 amount of time and rotate to the opposite direction when the trigger is removed. Configure timer to Function #25 and set the Trigger to #2. The trigger is connected to Dual Pole Dual Through (DPDT) relay which is used to change the polarity of the voltage going to the motor and timer is used to supply power for the t1 and t2 amounts. When trigger voltage is applied it causes the relay to switch the polarity and timer to generate power pulse. When trigger voltage is removed the polarity switches and the timer generates power pulse again. If the trigger voltage is not strong enough to switch the relay you can add another timer with Function #22 to boost the trigger signal and drive the relay.
10. The timer can be configured as a running daylight (RDL) cancellation module. RDL cancellation module temporarily turns off running lights when turn signal is activated. When the timer turn signal is off, the timer supplies constant power to the RDL, as soon as the timer senses turn signal cycling it turns off the output until the turn signal is turned off again. Configure the timer to Function #13 and set the Trigger to #2, and Output to Reverse.

11. You can use 5amp or 10amp timer to create a delay off timer. For example, you want for a car GPS unit or backup camera to come on when ignition first is turned On, and continue to be on for 30 min after ignition is turned off. Configure timer to Function #12 and set the Trigger to #2. The trigger is connected to ignition wire. When ignition receives power timer's output turns On. And when ignition voltage drops to 0v the timer starts the countdown and turns the output after a preset amount of time.
12. The timer can be used to control lights with effects like soft startup and dimming. Just configure timer Output Mode to Gradual output and create soft startup and dimming effects.
13. Many RV users add additional cameras, adding them to each side mirror.The question that comes up is how to activate them with cycling turn signals. The configuration is similar to the Running Daylight Cancellation configuration in example 10 above, but you will need one timer for the left camera and a second for the right camera. Configure each timer to Function #13 and Trigger #2. Set the t1 to at least 1 sec. Or set for example to 5 seconds if you want to keep the camera on for 5 sec after the turn signal is canceled. The timer Red wire needs to be connected to 12v (ignition) and the blue wire is connected to the turn signal. Once the timer senses the turn signal is on it activates the output (Yellow wire). Each turn signal cycle resets the timeout. Connect the timer's output Yellow wire to the camera activation wire on the display. If the display select input needs to be activated by ground then you can purchase the Sink adapter we sell, OR you can reverse the Timer's output. So without a turn signal, the timer output will be 12V and when the turn signal is on the output will not be energized. If the floating wire is not enough to activate the display select input then connect a small resistor (about 1k ohm) between the activation wire and the ground. The resistor would provide the pull to the ground to activate the camera select input on the monitor.
