Features:Increased the power supply anti - reverse connection function.The input and output are isolated by optical coupler, which enhances the anti-interference ability.Setting parameters can be remembered forever even if power failure.High stability, industrial grade circuit boards, class PLC.It has multiple functions to meet more application requirements.Low power consumption, superior performance.The product has a wide range of applications and can be used in many fields.Specification:Material: PlasticWeight: 42g/1.5ozRelay capacity: AC 220V10A / DC30V10AStatic current: 20mAOperating current: 50mAService life: 100,000 timesOperating temperature: -40~85Size: 64.2*34.8*18.5mm/2.5*1.4*0.1inchInstructions:1. The signal triggers the relay to close. When the time is up, the relay is disconnected during the delayA: invalid trigger again B: trigger again to restart timing C: restart relay reset to terminate timing2. The timing time T1 at the beginning of signal trigger and T2 at the time of relay snap-in time and T2 at the time of disconnection (reset) are adjustable3. Cycle use: connect T1, disconnect T2, and cycle indefinitely. T1 and T2 are both adjustable4. If there is a signal, the relay is engaged, keep engaged, the signal disappears and the timing starts. When the time is up, the relay is disconnected.During the delay, the signal is given again. The delay is cancelled, the signal disappears and the time is retimed.Package List:1 x Timer Relay.
