Specifications: Timing range: 0–999 seconds, 0–999 minutes, 0–999 hours Supply voltage: AC 110V–220V Relay rating: 20A Maximum working current: 10A Maximum power rating: 500W Dimensions: 79 × 26 × 43 mm Panel cutout size: 72 × 40 mm Instructions: For first use, allow 6 seconds after setting values for the module to save the configuration. Short press SET button: Enters time setting mode. The display blinks. Adjust T1 and T2 using + and – buttons. After setting, wait 5 seconds for automatic save. Long press SET button: Enters parameter setting mode. Two parameter groups are available: P0 and P1. Press SET briefly to toggle between P0 and P1. Use + and – buttons to select options within each group. P0 settings (timing unit selection): P0–0: Timing range in seconds (0–999 s) P0–1: Timing range in minutes (0–999 min) P0–2: Timing range in hours (0–999 h) P1 settings (relay operation modes): P1–0: Relay activates after delay T1 P1–1: Relay deactivates after delay T1 P1–2: Relay activates after delay T1, then deactivates after delay T2 (single cycle) P1–3: Relay deactivates after delay T1, then activates after delay T2 (single cycle) P1–4: Relay activates after delay T1, then deactivates after delay T2 (repeating cycle) P1–5: Relay deactivates after delay T1, then activates after delay T2 (repeating cycle) Example: For a 10-second activation followed by a 20-second deactivation (repeating): Set T1 = 10, T2 = 20 Select P0–0 (seconds) Select P1–5 (repeating cycle mode) Package Includes: 1 × Digital Display Time Relay
