Self-locking Relay Timer 555 DC 24V for Timed Control

Welcome to our shop! Discover our TRM01 time delay relay module, a versatile and reliable control component for your automation projects. This compact module (dimensions: 60 x 35 x 20 mm / 2.36 x 1.38 x 0.79 inches) is designed with high-quality components for stable performance and ease of use. **Main Features:** This intelligent module incorporates four predefined operating modes to meet a multitude of needs: ON delay, OFF delay, self-locking mode, and time-delay triggering mode. It is equipped with reverse polarity protection to prevent damage. You can choose from three operating voltages: 5V, 12V, or 24V DC. The delay time is precisely adjustable from 0.1 seconds to 120 seconds via a potentiometer. A major advantage: all defined parameters are saved in memory and are not lost after a power outage.**Technical Specifications:*** **Operating Voltage:** DC 5V, 12V or 24V (selectable).** **Consumption:** <80mA at 5V, <35mA at 12V, <18mA at 24V (and <1mA when the relay is inactive).** **Relay Load Capacity:** *Normally Open (NO) Terminal: DC 0-30V/10A, AC 0-250V/10A. * Normally Closed (NC) Terminal: DC 0-28V/10A, AC 0-125V/10A.* **Operating Temperature:** -20°C to +60°C (limit range: -30°C to +70°C).* **Package Weight:** Approximately 23 grams.** Mode Descriptions (F1 to F4):*** **F1 (Activation Delay):** After a delay T1 following power-up, the relay activates. A high pulse signal sent to interface X1 resets the cycle.* **F2 (Deactivation Delay):** The relay is activated immediately upon power-up. After a time T1, it deactivates. A signal on X1 resets the cycle.* **F3 (Self-Locking Mode):** A high pulse on X1 activates the relay. A new high pulse deactivates it.* **F4 (Level-Triggered Mode):** At startup, the relay is deactivated. Sending a continuous high signal to X1 immediately activates the relay. Even after the X1 signal disappears, the relay remains activated until the T1 delay expires, then it switches off.**Connections:*** **Power/Signal:** 3 terminals (DC+, DC-, X1 for input signal).* **Relay Output:** 3 terminals (COM common, NO normally open, NC normally closed).**Package Contents:** You will receive 1 time-delay relay module. Ideal for a wide range of control applications requiring delay and latching sequences.
