QMV TDR12V1 12 VDC SPDT Latching relay with on board switch and switch leads

The QMV TDR12V1 is a very cool relay. Have you ever wanted to have something turn on after 1 to 10 seconds after power is applied? The TDR12V1 relay is just the relay for you. This relay is a time delay-on 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:
• 1 - 10 Second delay turn on mini relay
• Circuit board design with dual LED's
• Requires a minimum of 9 volts to function
• Adjustable time delay turn on from 1 seconds to 10 seconds with internal potentiometer
• Relay resets once power is removed
• Internal Red LED to indicate power
• Internal Blue LED to indicate relay has cycled
• 10 amp / 15 amp rated contacts
• SPDT - Single pole Dual throw
• 12 Vdc rated coil with minimum 8 volt to trigger
• Power consumption @ 12Vdc 40 mA
• Screw terminals for easy connections up to 14 gauge wire
• Dimensions 7/8" (W) x 2-5/8" (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)
• CK - Normally open contact (Connects to common when relay latches)
• CB - 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 9 volts
Prevent high current components from switching on during vehicle start (up to 10 second delay)
Delayed Voltage inverter: Reverse the polarity to an component for a short duration
Flip-Flop: by using two of these you can create a flip-flop circuit of equal duration on alternating duration

Note: Adjustment of the time delay function multiple full rotations of the potentiometer

Note: Duration can be extended by replacing 100 uF capacitor with a larger value such as 200 uF or 1000 uF
