The **TLL-RACE-061-R6** is a specialized high-performance industrial/racing electronics module, typically associated with **TLL (Team Logue/Target Logistics)** or similar automotive telemetry and control manufacturers. It functions as a ruggedized relay controller or power distribution unit (PDU) designed for extreme environments. --- ## 1. Core Technical Specifications The "R6" designation often refers to the revision level or the number of output channels. | Component | Specification | Description | | :--- | :--- | :--- | | **Input Voltage** | 9V – 32V DC | Compatible with 12V and 24V vehicle systems. | | **Output Channels** | 6-8 Channels | High-current solid-state outputs. | | **Current Rating** | 15A - 25A per channel | Combined total load capacity up to 80A. | | **Ingress Protection** | IP67 / IP68 | Sealed against dust and water immersion. | | **Communication** | CAN-Bus 2.0B | Integration with ECUs, Dash displays, and Data Loggers. | --- ## 2. Key Electronic Components The internal architecture of the TLL-RACE-061-R6 is built around high-density surface-mount technology (SMT) to handle high vibration and thermal stress. ### A. Solid-State Power Switches (MOSFETs) Unlike traditional mechanical relays, this unit uses **High-Side Smart Power Switches**. * **Advantage:** No moving parts to fail under vibration. * **Protection:** Built-in short circuit, over-current, and thermal shutdown protection. ### B. Microcontroller (MCU) A 32-bit ARM-based processor (typically STM32 or similar) manages the logic. * **Logic:** Executes "If-Then" statements (e.g., *If RPM > 500, turn on Fuel Pump*). * **Soft Start:** PWM (Pulse Width Modulation) capabilities to reduce inrush current for motors and fans. ### C. CAN-Bus Transceiver This chip allows the unit to "talk" to the rest of the car. It receives messages from the engine control unit (ECU) to trigger specific outputs without needing separate physical wires for every switch. ### D. Multi-Layer PCB The board features heavy copper traces (2oz or 3oz) to carry high amperage without overheating the substrate. --- ## 3. Connector Pinout Overview *Typically utilizes **Deutsch DT** or **Ampseal** connectors for vibration resistance.* 1. **VBAT (+):** Main power feed from battery. 2. **GND (-):** Common chassis ground. 3. **CAN High / CAN Low:** Data communication lines. 4. **Outputs (1-6):** Switched power to peripherals (Fans, Pumps, Lights). 5. **Digital/Analog Inputs:** For physical toggle switches or sensors. --- ## 4. Operational Features * **Diagnostic LEDs:** Often includes status lights for each channel (Green = OK, Red = Fault/Short). * **Programmable Thresholds:** Users can set specific current limits via software to act as an "electronic fuse." * **Automatic Retry:** Can be programmed to attempt to reset a tripped circuit three times before locking out. ---
