Digital Delay Timer Module for LED Display, 12V DC Control Relay Switch

Increase the power supply anti-reverse function. Parameters are saved after power-on for persistent memory retention. Signal terminal voltage remains stable for extended periods. Designed for industrial-grade stability, compatible with PLC systems. Dimensions: 64.2 mm × 34.8 mm × 18.5 mm. Operating mode selection: After power-on, press and hold K12 for 12 seconds to enter setup mode. Use P1-1 to P1-4 to select operating modes. P1-1 Mode (Single-shot timer): A trigger signal activates the relay; after a user-defined time T, the relay deactivates. To set time T: Press K2 to begin editing the hundreds digit (display flashes), then press K3 to adjust; repeat for tens and units digits. Press K2 again to shift decimal point position. Decimal point placement defines time units: - With decimal point in hundreds position: 0–999 minutes - With decimal point in tens position: 0–99.9 seconds - Without decimal point: 0–999 seconds P1-2 Mode (On-Off cycle): A trigger signal starts countdown. Relay activates after X seconds, remains on for Y seconds, then turns off. Users can set both X and Y using the same digit-editing procedure as P1-1. Blue LED indicates relay OFF time setting. P1-3 Mode (Continuous cycle): Relay activates for X seconds, deactivates for Y seconds, repeating indefinitely. X and Y are set using the same method as P1-2. Relay Specifications: AC 220 V / 10 A or DC 30 V / 10 A. Quiescent Current: 20 mA Operating Current: 50 mA Operating Voltage: 10–16 V (custom ranges available) Signal Input Voltage: 4–20 V (custom ranges available) Mechanical Life: Approx. 100,000 cycles Operating Temperature: –40 °C to +85 °C Material: Printed Circuit Board Package Includes: 1 × DC 12 V Delay Timer Control Switch Module
