RC-T2off-357 Delay Timer by VideoLink

The RC-T2off-357 delay timer is a compact module from the VideoLink brand, designed for automatic activation of actuators after a fixed time following disconnection from the control line. The device ensures reliable operation in drone and quadcopter systems, particularly in the Stacks (FC+ESC) category, where delayed activation of actuators is required for safety and synchronization.

Operation Description

The module outputs a current pulse 3, 5, or 7 seconds after the board is disconnected from the control line. Constant power is not required for the timer to activate: even if power circuits are disconnected, the timer can perform its function. The ability to discharge (reset the timer) by operator command is provided, allowing remote control over the process. Control is performed by sending pulses of a specified duration from the control panel via a signal wire, ensuring simple integration with existing command and control systems.

Application

The RC-T2off-357 is suitable for use in unmanned systems where delayed activation of actuators is necessary after loss of control signal or during a special startup procedure. The module is compatible with flight controllers and ESCs used in the Stacks (FC+ESC) category and is useful in cases where the sequence of circuit activation or protection against accidental startup is important.

Technical Specifications

• Dimensions and weight: 30x20x15 mm, 11 g
• Supply voltage: +5÷7 V
• Current consumption: no more than 70 mA
• Load resistance: no less than 1 Ohm
• Initial output pulse voltage: no less than 10 V
• Output pulse duration to 3 V level: no less than 3 ms
• Output pulse energy: no less than 200 mJ

Compact dimensions and low weight allow the module to be installed even in densely packed assemblies without significantly affecting the apparatus's mass and balance. Low current consumption makes it an energy-efficient solution for drone battery systems. A reliable output pulse with high initial voltage and specified energy ensures correct activation of most actuators.
