Features There are many voltage and time ranges to choose from, both the switch-on time and the switch-off time are adjustable It is a time relay module with high precision, stable and reliable performance Widely used in timer operating equipment, recurring test circuits of machines, intermittent pumps of aquariums, etc Supports 2 modes, the mon mode (once) and the cycle mode, and you can easily switch the mode by adjusting the jumper Connect 2 wires of "Key" if the module should work repeatedly after switching on Specifications: Type: DC5V,0-30min/DC12V,0-120min/DC12V,0-24h/DC24V,0-15min/DC24V,0-30min (Optional) Standby current: <10 mA. Dynamic current: 45mA at 12V; 90mA at 5V; 30mA at 24V Contact: 1 group NO+NC. Load capacity: 10 A (AC0-250V, DC0-30V). Size: 70 x 20 x 18 mm/2.75 x 0.78 x 0.7 inches. Time accuracy: maximum value x 0.001. Mon. Mode: 1. The module power-on, when triggered, the relay is switched on, timer delay off. 2. If the delay process is triggered and triggered again, the delay is immediately interrupted. Cycle mode: 1. The module power-on, when triggered, the relay is switched on, (T1) timer delay off. (T2) Time Delay On Such cycle. T1 and T2 are each set by two adjustable resistors. 2. If the delay process is triggered and triggered again, the delay is immediately interrupted. Package includes: 1 x Time Relay Module Package List
