QMV TDR12V4 6-30 VDC SPDT 0.1 seconds to 999 Minutes Adjustable Time Delay On or Off Relay with looping

The QMV TDR12V1 is a very cool relay. Have you ever wanted to have something turn on or off after 0.13 seconds to 60 Minutes after power is applied? The TDR12V5 relay is just the relay for you. This relay is a time delay-on or delay off relay with adjustable timings allowing you to control any device. This relay is perfect for a variety of things such as delayed amplifier turn on. It utilizes mini relay with single pole dual throw contacts. It easily switches 10 amps of current and peaks of 15 amps.

Features:
• 0.13 seconds to 60 Minutes delay turn on or off mini relay
• Circuit board design with dual LED's
• Relay will operate on a wide spectrum of voltage from 6 volts to 30 volts DC
• Supports micro USB 5.0V power supply
• Adjustable time delay turn on from 0.13 seconds to 60 Minutes with push buttons and LCD display
• Reverse polarity protection
• Relay resets once power is removed
• 4-button controls for setting on operating time delay with emergency stop function
• 3.0 Volt - 24 Volt triggered inputs have optocoupler isolation to prevent dc ground issues or short circuits
• 10 amp / 15 amp rated contacts
• SPDT - Single pole Dual throw
• Non-volatile memory - After the relay is powered down, all parameter settings are not lost
• Power consumption @ 12Vdc 20 mA idle, 50 mA operating
• Screw terminals for easy connections up to 14 gauge wire
• Dimensions 1-1/2" (W) x 2-1/2" (L) x 3/4" (H) with terminals

Contact configuration:
• GND - Ground all-time, as this is what grounds the circuit on the relay
• VCC - 12 volt positive connection to trigger the relay
• COM - Common latching relay connection (Can be positive or negative depending on your need)
• NO - Normally open contact (Connects to common when relay latches)
• NC - Normally closed contact (Connects to common when relay is un-energized or at rest)

Uses: Low voltage trigger: input will trigger with as little as 3 volts Delayed turn onPrevent high current components from switching on during vehicle start (up to 999 minute delay) Delayed Voltage inverter: Reverse the polarity to an component for a short duration Looping timer: Trigger a pump to run for 5 minutes every 2 minutes for a certain amount of cycles or infinite while relay is powered Delayed turn off: Trigger a a device to turn off 5 minutes after a trigger is sent

Operating Modes:
• P1.1 - Requires trigger to initiate timer for OP time setting, then shuts down. Re-triggering will not trigger again until power it removed (Time delay off with NO and NC contacts)
• P1.2 - Requires trigger to initiate timer for OP time setting, then shuts down. Re-triggering will trigger again for OP time setting (Time delay off with NO and NC contacts)
• P1.3 - Requires trigger to initiate timer for OP time setting, then shuts down. Re-triggering will cause relay to stop timer and reset (Time delay off with NO and NC contacts)
• P1.4 -
• P2.1 -
• P2.2 -
• P3.1 - Requires trigger to initiate timer for time delay on, OP time setting is the delay, relay turns off after CL time. Re-triggering will cause relay to stop timer and reset. LOP cycles can be set for this mode (Time delay on with NO and NC contacts)
• P3.2 - No trigger required to initiate timer for time delay on, OP time setting is the delay, relay turns off after CL time. LOP cycles can be set for this mode (Time delay on with NO and NC contacts)
• P-4 - Signal hold function. If trigger is present the relay remains on, when trigger is removed the relay stays latched for OP time. Re-triggering will cause relay to stop timer and reset. (Signal hold on with delayed off - NO and NC contacts)

Legend:
• OP - On time
• CL - Off time
• LP - Loop (Total number of cycles)

Timing range:
• XXX. Decimal point is in one place, timing range: 1 second to 999 seconds
• XX.X decimal point in ten, timing range: 0.1 seconds to 99.9 seconds
• X.X.X. The decimal point is fully illuminated, the timing range is from 1 minute to 999 minutes

Instructions:

1. Determine what mode is required for your application
3. According to the working mode of the relay, in the main interface (when the module is powered on, it will flash the current working mode (default P1.1 mode), then enter the main interface "press and hold the SET button for 2 seconds and then release" to enter the mode selection.
5. You can select the appropriate mode by selecting the mode to be set P1.1 - P-4 by short pressing the UP and DOWN buttons.
7. Press the SET button to set the mode.
9. Display will flash OP ON time, CL OFF time, LOP cycle number “---” means unlimited.
11. To adjust OP/CL/LOP time use the UP, DOWN to adjust the time value.Buttons support long press (rapid increase or decrease) and short press (increase or decrease 1 unit)
13. Select the decimal point position by short pressing the STOP button, select Timing range (corresponding time 0.1 seconds to 999 minutes); short press the SET button to set the next parameter of the current mode, the process is the same as above.
15. After setting the parameters of the selected mode, press and hold the SET button for 2 seconds to release, the currently set mode will flash, then return to the main interface and set the parameters successfully.
17. Main interface: “000” (no decimal point) is displayed when the relay is not working, and the decimal point is clear when the relay is working.
19. Mode selection interface: long press SET button to enter, after setting is completed, long press SET button to exit, return to the main interface
