Manhua MT316S 12V DC Timer Switch with Seconds | 16A, Solar & Irrigation

Key Features

Timing accurate to the second rather than the minute is the real distinguishing feature here, useful for short repeated cycles like solar charge management or pulsed irrigation that a standard daily/weekly timer simply can't handle at that resolution. It's worth flagging a correction too: earlier listings for this exact product had quoted the 25A rating that actually belongs to its AC-powered sibling, corrected here to the true 16A rating for this 12V DC model.

Up to 28 on/off settings a day gives genuinely fine control over a schedule, whether that's staggering solar charge windows or running short irrigation pulses through the day rather than one long soak. DIN rail mounted for a standard distribution board install, with battery backup holding the programmed schedule through a power cut.
