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

Increase the power supply anti-reverse function. Parameters are saved after power-on for permanent 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: Single-trigger timer mode — A signal triggers the relay; after a user-defined time T, the relay de-energizes. To set time T: - Press K2 to start flashing the hundreds digit; press K3 to adjust. - Press K2 to flash the tens digit; press K3 to adjust. - Press K2 to flash the units digit; press K3 to adjust. - Press K2 again to enable decimal point shift: - With decimal point lit: range is 0–999 minutes (hundreds = minutes), or 0–99.9 seconds (tens = seconds, units = tenths). - Without decimal point: range is 0–999 seconds. - Press K2 once more to confirm setting. P1-2: On-Delay + Off-Delay cycle — A signal triggers the relay ON for X seconds, then OFF for Y seconds. Users can set both X and Y using the same digit-adjustment method as P1-1. Blue LED indicates OFF-time setting. P1-3: Continuous ON/OFF cycling — Relay turns ON for X seconds, then OFF for Y seconds, repeating indefinitely. X and Y are set similarly to 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 DC (custom voltage ranges available upon request) Signal Input Voltage Range: 4–20 V DC (custom ranges available upon request) Mechanical Life: Approx. 100,000 operations Operating Temperature: –40 °C to +85 °C PCB Material: Printed circuit board Package Includes: 1 × DC 12 V Delay Timer Control Switch Module Note: Color appearance may vary slightly due to lighting and display settings.
