CuriousTech Timers and other embedded solutions

 Quality designs and low cost

Email for any questions before or after ordering: greg@curioustech.net  Custom hookup diagrams and settings are always discussed before ordering, but after is fine as well.

Options are added when ordered, and units are tested and shipped within 24 hours.
Prices include lowest cost shipping anywhere in the world (no problem so far with US, UK, Italy, Ireland, Turkey, Austria, Russia...)
Although the features are well thought out with over 6 years of testing, many options are not listed, such as reversed logic on timers, more inputs, and custom features so just ask if there's something you want changed.
 
Timer Modules
Less expensive, smaller, uses less power, and more versatile than any timer on the market.   No relays, no guesswork or waiting an hour to see if the timer knob was turned right.  Solid state, digital programming and accurate.

Not sure what timer you need?  Describe the application and get the perfect timer. Easy as that.

Timer modules are highly versatile:
  Input voltage: 6.0-30VDC or 2.0-5.5VDC by request
  Quiescent current, 6.0-30VDC: 2.2mA,  2-0-5.5VDC: 45uA
  Output: 200mA Darlington Optocoupler: 1-40VDC open collector/open emitter
  3 Inputs: 2-20VDC (or 5V 20mA logic out for customized designs)
  250us debounce on inputs (can be ordered with longer times)

Order any timer and request your own design within the possible specifications for no additional charge.  Note: Design-a-timer may take extra time depending on the changes required.
   
 
TMR-1  Hold-On Timer / Safety Timer / Shutdown Timer
   $17.95   (Purchase above)

Shutdown timer example:
Input 1 -> ACC or IGN
Input 2 -> (Timer Enable) PC internal power (5V or 12V)
Output -> Relay or circuit requiring <200mA

Programmable timer: 1 minute to 45 days. Same programming as remote systems above.

Input 1 ON turns output ON, (if output already on, it stays on and stops timer).
Input 1 OFF starts timer if input 2 is ON.  Timer or input 2 will turn output off.
Button tap turns output ON, but not off.
Notes: Connect input 2 to power if not needed (to enable timer always)
________________________
Hybrid sleep timer example:
Input 1 -> IGN (connect to PSU IGN)
Input 2 -> PC internal power (5V or 12V)  (connect to Power for timer only)
Opto In -> Power
Opto Out -> Relay supplying power to PSU

IGN on turns relay on to power PSU. IGN off starts timer (1 hour for example) and will shut off power when timer ends or Input 2 goes off.
Stay-on Example:
Insert blue and white (ISO Out is white) inline where PSU IGN input is.
Use any switch.
When switch is off, TMR-1 will be passive.
When switch is on, output will stay on when IGN is turned off and start timer.
  (turn switch off any time to turn off and end timer)

 
TMR-2  Standby Timer
 
 
$17.95 (Purchase above)

Pulses output when the timer ends.  Timer has status and can be started and stopped several ways.

As a standby timer:
  2-Wire Output -> ACPI power button
  Input 1 -> Software controlled output
  Input 2 -> PC power when on such as USB 5V or fan if off in standby (optional)
  Output 2 -> 5V high when timer active (optional)

Programmable timer: 1 minute to 45 days.  Same programming as remote systems above.

Input 1 pulse <500ms starts timer.
Input 1 pulse >500ms stops timer.
Input 2 transition to high stops timer.
Output 1 is pulsed for 500ms at end of time.
Output 2 is high when timer is active.
Button tap pulses output and disables timer.
Example:  (DSR may not be green.  I'm just out of colors.)


Pulsing DTR (on, delay 200ms, off) starts timer.
Pulsing DTR (on, delay 800ms, off) stops timer.
DSR will be high if timer is active.

The software (not provided) can start the timer and enter sleep.  Upon resume, check DSR to determine if timer caused resume. If PWRMon is not used, pulse DTR for 1 sec to turn off timer.
If DSR is low, then timer causes wake.  Hibernate or do unattended work at that point.
 
TMR-3  On/Off to Pulse with on-sense and on-delay
  
$17.95 (Purchase above)

Turns a device on by pressing power button when input signal changes, with adjustable time delay for ON and input from device to ensure proper on/off state.

Options when ordering:
  On-sense enabled/disabled
  Time scale (seconds, minutes, or hours)
  Output pulse width
  External button with LED

Example applications would be turning a laptop on/off with ignition, or turning a monitor on/off when the PC turns on/off while not getting out of sync. Plus a manual button.

Programmable delayed on-timer (disabled or 1 second to 18 hours):
  Hold button for 5 seconds. Tap for number of seconds. 0-255 (default 10)
  Hold button for 10 seconds. Tap for number of multiplier. 1-255 (default 1)
  Hold button for 15 seconds. Tap for number of ON pulses. 1-255 (default 1) 250ms on, 250ms off.

Input 1 -> Source that turns on and off (2-20VDC).
2-Wire Output -> The momentary switch to control.
Input 2 -> Controlled device's internal power when on (2-20VDC).

Button tap pulses output always.
 
TMR-4  A multitude of timers. On-Delay, Off-Delay, Pulse, etc.
  
$17.95 (Purchase above)

Dual second/minute timer with exact times from 1 second to 42 days.
Delayed on timer for devices such automotive amplifiers, for anti-thump / speaker pop elimination.
Delayed off timer for extending powered time, ignoring short power-offs, or as a timed-on from a pulse.
Delayed pulse from constant or pulse

Note: Use the same precautions as with most head units. Powering devices without a remote-on input may require a relay.  The maximum limit for remote-on inputs is 50mA and is typically much lower, so at least 4 amplifiers may be safely connected.  The standard Bosch automotive relay consumes 160mA, so this can safely power only one large clunky relay or several more efficient ones.

Default:
  Input1 ON  starts on-timer, turns output ON at end of time
  Input1 OFF starts off-timer, turns output OFF at end of time

Button tap toggles output and cancels timers. (Compatible with C output of above PC Remote)

Basic connection for amplifiers:
  GND (Black)      -> Ground
  +12V (Red)        -> Constant, or Input source (No off-delay or manual switching if source used)
  Input (Blue)     -> Trigger: (2-20V source HU, USB, ACC, IGN, remote output, etc.)
  Collector (Yellow)-> +12V source normally (or 2 sides of switch/button)
  Emitter (White) -> Amp remote input      ("                   ")
Programming:
   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.

  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)
Mode Seconds Minutes Seconds
