1. 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 continues power to flow to the current even if 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. 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. Timer is set to Function #2 and Trigger #4.
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 Self latching circuit with control from external source like vehicle ignition wire. Timer is set to Function #13 and Trigger #1. Circuit consumes no power during the off state. If 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. Timer is set to Function #12 and Trigger #2.
6. Function #21. Single Shot Time Reset and Hold on Trigger. One of the application is to create light control where a button is used to activate the light. The light will stay on until set time expires. Push ofthe button while lights are 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. Timer might be used to boost the output of another signal or control wire. The output of the timer will mimic logical state of the trigger wire. The output can also be changed to be opposite of the control signal.
8. Timer might be used to create a button interface. When button is pushed timer supplies power to the output for preset time. Secondary push of the button will turn the output off. 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 like shown below. Let's says you need for motor to rotate one direction when trigger is applied for X amount of time and rotate to opposite direction when trigger is removed. Configure timer to Function #25 and set the Trigger to #2. Trigger is connected to Dual Pole Dual Through (DPDT) relay which is used to change polarity of the voltage going to the motor and timer is used to supply power for X amount. When trigger voltage is applied it causes relay to switch the polarity and timer to generate power pulse. When trigger voltage is removed the polarity switches and 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. Timer can be configured as running daylight light (RDL) cancellation module. RDL cancellation module temporary turns off running lights when turn signal is activated. When timer turn signal is off timer supplies constant power to the RDL, as soon as it senses turn signal cycling it turns off the output until the turn signal is turn off again. Configure timer to Function #13 and set the Trigger to #2, and Output to Reverse.

11. You can use 5amp or 10amp timer to create delay off timer. For example, you want for a car GPS unit to come on when ignition first is turned On, and continue to be on for 30min 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. During the Off phase timer consumes about 5ma of current.
12. The following circuit allows to accomplish delay Off function (as in example #11) but with 0 power consumption after the output turns Off. Only 10amp timer version can be used as it has separate wire to power internal circuitry. For example, you want for a car GPS unit to come on when ignition first is turned On, and continue to be on for 30min 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 supplies the power to itself through a diode. And when ignition voltage drops to 0v the timer starts the countdown and turns the output after a preset amount of time.
13. 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.
