ManHua MT316S AC Timer Switch with Seconds | 25A 220VAC, 1 Sec to 168 Hrs

Key Features

Second-level timing precision from 1 second up to 168 hours, with 28 daily programs, rated for 25A on a standard 220V AC circuit.

That 1-second-to-168-hour range is unusually wide for a DIN rail timer, most competing models step in minutes rather than seconds, which matters specifically for applications where a school bell or a piece of industrial machinery needs to fire at an exact moment rather than somewhere within a minute-wide window.

Specifications

• 220V AC, single phase, 25A rated load
• Programming: seconds, daily and weekly, 1 second to 168 hours
• Up to 28 ON/OFF settings a day
• DIN rail mount, battery backup

Common uses include school bell systems, street and security lighting, irrigation, and industrial machinery scheduling where minute-level timing genuinely isn't precise enough for what's being automated.

Best Uses

School bell systems, street and security lighting, irrigation and industrial machinery scheduling, anywhere minute-level timing isn't precise enough for what's being automated.
