YWBL-WH Adjustable Cycle Timer Delay Module, DC 5V 12V 24V On/Off Switch Relay Module for Machine Repetitive Test Connect 2 wires of "Key" if you need module to work recurrently after power on. It is a timer relay module with high precision, stable and performance. Timer module is widely used on timer operating equipment, machine repetitive test circuit, fish intermittent pump, etc. Specifications: Type: DC5V,0-30min/DC5V,0-24hr/DC12V,0-120min/DC12V,0-24hr/DC24V,0-15min/DC24V,0-30min (Optional) Quiescent Current: <10mA Dynamic Current: 45mA@12V; 90mA@5V; 30mA@24V : 1 group NO+NC Load Capacity: 10A(AC0-250V, DC0-30V Size: 70×20×18mm / 2.75×0.78×0.7" Time Accuracy: value*0.001 Mon. Mode: 1. The module Power-on, When triggered the relay is switched on, timer delay off. 2. When triggered on the delay process, again triggered, it will immediately interrupt the delay. Cycle Mode: 1. The module Power-on, When triggered the relay is switched on, (T1) timer delay off. (T2) timer delay on. Such cycle. T1 and T2 are set by two adjustable resistors, respectively. 2. When triggered on the delay process, again triggered, it will immediately interrupt the delay. Package Includes: 1 × Timer Relay Module
