QMV TDR5V1 5 VDC SPDT 1 - 10 Seconds Adjustable On Time Delay Relay
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 5.5 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
- SPST - Single pole Single throw
- 5 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 - 5 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
Current limiter: 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

Relay Pinout Diagrams Explained
A relay pinout diagram shows the function of each terminal (pin) on a relay and how the internal connections work. It helps you wire the relay correctly for your project.
1. Basic Relay Anatomy
Most automotive relays have two main parts:
- Coil – An electromagnet that switches the relay on/off (low current side)
- Switch Contacts – The high-current switch that turns your accessory on/off
2. Most Common Automotive Relay: 5-Pin SPDT
This is the standard relay type used with sockets like BRSCN, BRSPC, BRSS, etc.
| Pin | Name | Function |
|---|---|---|
| 30 | Common | Power input (goes to the load) |
| 87 | Normally Open (NO) | Closed when relay is energized (ON) |
| 87a | Normally Closed (NC) | Closed when relay is de-energized (OFF) |
| 85 | Coil Ground | Negative side of coil |
| 86 | Coil Positive | Positive side of coil (+12V trigger) |

85 ───────── 86
How It Works:
- No power to 85/86 → Current flows between 30 and 87a
- +12V applied to 85/86 → Coil energizes → Current flows between 30 and 87
4. How to Read a Relay Pinout Diagram
Most relay pinout diagrams include the following elements:
- A box or outline representing the relay body
- Pin numbers clearly labeled next to each terminal
- Internal connections shown with lines or dotted lines
- Coil symbol (usually a rectangle or spring-like coil)
- Switch contacts shown with an arrow indicating movement when the relay is energized

Coil
Understanding the Symbols:
- 30 — Common terminal (input power)
- 87 — Normally Open (NO) contact
- 87a — Normally Closed (NC) contact
- 85 & 86 — Coil terminals (control side)
When the relay coil is energized (pins 85/86 powered), the internal switch moves from 87a to 87.
Quick Wiring Examples (5-Pin Relay)
1. Basic On/Off Circuit (Most Common)
Used for lights, fans, fuel pumps, horns, etc.
- 86 → Switched +12V (from switch, toggle, or ECU output)
- 85 → Ground (or switched ground)
- 30 → Constant +12V Power (from battery or fuse box)
- 87 → Output to Accessory (lights, fan, etc.)
- 87a → Not used (leave disconnected)
2. Changeover / Dual Circuit Setup
Use both 87 and 87a when you need to switch between two different circuits.
- 30 → Input Power
- 87 → Circuit A (ON when relay is energized)
- 87a → Circuit B (ON when relay is OFF)
- 85 & 86 → Coil control
3. Typical Pin Connections Summary
| Pin | Connection | Typical Wire Color | Purpose |
|---|---|---|---|
| 30 | Constant +12V | Black (BRS14E & BRS12E) | Power Input |
| 87 | To Accessory | Green (BRS14E & BRS12E) | Power Output (ON) |
| 87a | Optional 2nd Circuit | Blue (BRS14E & BRS12E) | Power Output (OFF) |
| 85 | Ground | White (BRS14E & BRS12E) | Coil Negative |
| 86 | Switched +12V | Red (BRS14E & BRS12E) | Coil Positive |
Tip: Always use a fused power source on pin 30 for safety.
Basic 5-Pin Relay Wiring Harness
Battery +12V ──► [Fuse] ──► Pin 30 (Common)
Pin 87 ──► Accessory (Lights / Fan / Pump / Amp etc.)
Pin 86 ──► Switched +12V Trigger
(from switch, headlight wire, remote turn-on, etc.)
Pin 85 ──► Ground
Pin 87a ──► (Optional - Not used in basic setup)
Recommended Wiring (Empty relay socket or spade connectors (Not BRS14E & BRS12E):
- Pin 30 — Red wire with inline fuse (closest to battery)
- Pin 87 — Red or Blue wire to device
- Pin 86 — White or Pink trigger wire
- Pin 85 — Black ground wire
Dual Output (Changeover) Relay Harness
Pin 30 → Constant +12V (Fused)
Pin 87 → Circuit A (ON when relay activated)
Pin 87a → Circuit B (ON when relay is off)
Pin 86 → Trigger +12V
Pin 85 → Ground
