TRM01 Time Delay Relay Module utilizes high-quality components for stable performance and ease of use. It's widely applicable in various control situations requiring delayed self-locking. This module comes with 4 preset functions to meet diverse application needs, and custom functions can be added upon user request. Features: Includes anti-reverse power supply protection to prevent module damage. Available in three working voltage versions: 5V / 12V / 24V for user selection. Delay time can be set arbitrarily between 0.1 seconds and 120 seconds. Supports delay on, delay off, self-locking, and trigger delay functions. Parameters are saved, so settings are retained even after power loss. Specification: Working Voltage: DC 5V, 12V, 24V (Optional) Working Current: ≤80mA at 5V (≤1mA when relay is not operating); ≤35mA at 12V (≤1mA when relay is not operating); ≤18mA at 24V (≤1mA when relay is not operating) Load Capacity: Normally Open Port: DC 0-30V / 10A, AC 0-250V / 10A; Normally Closed Port: DC 0-28V / 10A, AC 0-125V / 10A Working Temperature: -20 ~ 60℃ (Limit Range -30 ~ 70℃) Size: 60 * 35 * 20mm / 2.35 * 1.38 * 0.79in Package Weight: Approx. 23g Module Function: Users can select one of the following four functions by pressing the button. Delay time can be adjusted using the potentiometer. Delay time T1 can be set between 0.1 seconds and 120 seconds. Function F1: Power-on Delay: After a delay of T1 from power-on, the relay will engage and send a high-level pulse signal to the X1 interface at any time.
