DDC-331 Automation Delay Timer 12VDC - (AD30553)

Description:

New 12Vdc automation timer module with relay switch and high-quality plastic case. It simplifies what the user needs, uses an optocoupler to isolate the input from the output. Configuration parameters can be stored after power-off. The voltage terminal signal can be maintained for a long time. The relay output is a passive contact with no load, and it controls the line in its ON-OFF state.

Working mode selection:

1. After powering on, press and hold K1 for 2 seconds, then select the mode (P1 to P4), press K2 to enter the mode.

    a. P-1: Monostable trigger delay: a signal to trigger the relay, timing starts, then the relay disconnects.

    b. P-2: A trigger signal and the negative count begins, T1 seconds later the relay activates, T2 seconds later the relay disconnects.

    c. P-3: The relay activates for T1 seconds, then disconnects for T2 seconds, in an infinite cycle. Users can set T1 and T2 times.

   d. P-4: The relay activates when the trigger signal turns ON, when the trigger signal turns OFF the digital countdown begins, and the relay deactivates when T1 reaches 0.
