Unlike generic consumer 555 timer relays, these are microprocessor controlled electronic timers designed for versatility, allowing for precise timing and complex, customized logic.
Important: These are the only consumer MOSFET switch timers so they are silent, never wear out, can switch high current, are extremely efficient and can run at a very wide voltage range.  However, they are not designed for any specific load.  Inductive loads (relays, solenoids) require a flyback diode (free with request) to ensure proper function, with diagrams to explain hookup.
Not sure what you need?  Describe the application and get the perfect timer. Easy as that.

AutoCharge  7A 5V
$13.95
Charge timer for USB devices.

Programming is set based on mode (see table below), i.e the on time cane be in minutes or hours, while off in days from 0 to 255.

Current sensing is in 100mA increments (see table). When current drops below programmed threshold for a few seconds, charging is paused for the off duration.

Note, this will not work with most portable power banks which turn off when current drain stops because the AutoCharge device is undetectable.

Time modes (setting 2 and 3):
  0     1      2       3    4   5      6
  1m, 10m, 30m, 1h, 6h, 12h, 24h

Current setting (setting 4):
 0=50mA, 1=100mA, 2=200mA....
LED (setting 5):
 0=off, 1=pulse when charging, 2=sensing)		 AutoCharge USB charger timer
 
Button tap toggles output and cancels timers (will pulse output if pulse mode used, or start/stop in repeat mode).

 Programming for TMR-2 (All settings are stored in EEPROM and can be factory programmed, and user programmed at any time)

 Units made before April 2013:
    Hold button, LED will off-blink at 5, 10, 15, 20 second intervals. Release after 5 for option 1, etc.  Tap for desired number.
   No input for 5 seconds ends programming. No input disables option (sets to 0).
   Options 1, 2, 3 confirms with blinks: on-time, pause, off-time, pause, multiplier.  Option 4 confirms only option 4.
Units made April 2013 - Dec 2014:
    Hold button, LED will off-blink at 4, 8, 12, 16, 20 second intervals. Release after 4 seconds to view settings.  Release after 8 for option 1, etc.
  Tap for desired number.  No input for 5 seconds ends programming. No input disables option (sets to 0).  LED will blink number entered.

  1. On-timer (0-255)  Timed delay after input ON to turn output ON or pulse
  2. Off-timer (0-255)  Timed delay after input OFF to turn output OFF
  3. Multiplier (1-255) Multiplies on and off timer by number of minutes/seconds.
  4. Mode (See Mode Table)

Examples:
On Off Mult Mode Description
10 10 1 0 In-High = 10 sec delay to ON, In-Low = 10 sec to OFF (Default)
   In < 10 seconds = never ON (Delay On Make & Break)
       
10 20 6 1 In-High = 1 hour delay to ON, In-Low = 2 hour delay to OFF
0 30 1 1 In-High = Instant ON, In-Low = 30 min delay to OFF
    In-Pulse = 30 minutes on  (Delay on Break)
       
10 0 1 0 In-High = 10 sec delay to ON, In-Low = Instant OFF
     In < 10 seconds = never ON (Delay on Make)
       
10 2 1 2 In-High/Pulse = 10 sec delay to pulse, In-Low = 2 sec delay to pulse
10 0 1 2 In-High/Pulse = 10 sec delay to pulse, In-Low = nothing
0 10 1 2 In-High/Pulse = pulse, 10 second delay, pulse
10 10 1 3 Same as mode 2 but minutes instead of seconds
1 10 10 4 In-High/Pulse = 10 sec delay to ON, ON for 100 sec
10 0 1 4 In-High/Pulse = 10 sec delay to Toggle
1 60 1 5 In-Pulse = 1 min delay to ON, ON for 60 min
15 2 1 13 Off for 15 mins, ON for 2 mins, repeat while input ON

Example:  Setting delay-on to 5, then selecting display which reads 5, 3, 1, 1
 
 
Custom designs are not impossible, but all the timers above are the most versatile on the market today and fit most needs.
