Feature: 1. The relay module is made of plastic material and can control DC or AC loads within 30A 2. Relay module adopts a permanent memory mode when power off, and can start and stop the switch board with one button 3. The high-power relay module has strong anti-interference ability, stable performance and reliable quality 4. Adopt 9.5mm black fence type terminal, standard 30A terminal, high-power relay module is stable and firm 5. Delay time range 0 second to 100 minutes can be adjusted arbitrarily, minimum 1 second adjustable Specification: Item Type: High‑power Relay Module Product Model: YYLOCK-2 (24V) Output Capacity: AC 250V/30A, DC 30V/30A or less Strong Anti-Interference Ability and Stable Performance Function List Description: P--1: Self-locking Turn on the signal relay once (work), and stop (stop) the signal relay again P--2: There is a signal, the relay is closed, the input signal is disconnected, and the output is powered off after a period of time; the signal is kept output during the delay period, and the timing stops, which is equivalent to the power-off delay P--3: Give the signal, the output will automatically stop for a period of time; the signal will be invalid during the delay period If the signal is directly short-circuited, it can be realized: the power-on output will be disconnected for a period of time until the power is off P--4: The signal exceeds a certain time, the output works; the signal disappears, the timing is cleared, and the output stops If the signal is directly short-circuited, it can be realized: the relay will automatically pull in after a period of power-on delay until the power is off.
