Features Increased the power supply anti ‑ reverse connection function.Low power consumption, superior performance. 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.The product has a wide range of applications and can be used in many fields. High stability, industrial grade circuit boards, class PLC.It has multiple functions to meet more application requirements. The signal terminal can hold the voltage signal for a long time. Specification: Material: Plastic Weight: 42g/1.5oz Voltage: 12V Relay capacity: AC 220V10A / DC30V10A Static current: 20mA Operating current: 50mA Signal voltage: 4V~20V Service life: 100,000 times Operating temperature: -40~85℃ Size: 64.2*34.8*18.5mm/2.5*1.4*0.1inch Instructions: 1. The signal triggers the relay to close. When the time is up, the relay is disconnected during the delay A: invalid trigger again B: trigger again to restart timing C: restart relay reset to terminate timing 2. 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 adjustable 3. Cycle use: connect T1, disconnect T2, and cycle indefinitely. T1 and T2 are both adjustable 4. 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.
