ENDA ATM9321-230 is an industrial analog timer relay with a digital display and 230V AC supply, designed for applications where equipment must be switched according to a preset time interval.

Unlike basic analog timer relays, the ATM9321 combines easy analog adjustment with a digital indication of the timer value. This allows operators to view and change the timing setting quickly without complex programming.

Three selectable timing ranges are available:

• 0...9.99 minutes
• 0...99.9 minutes
• 0...999 minutes

This makes the same timer suitable for both short timing cycles and industrial processes requiring considerably longer operating periods.

The ATM9321 provides two selectable operating functions:

Mode A - On Delay: the control output is energized after the preset time has elapsed.

Mode B - Timed Output: the control output remains energized during the preset timing period.

External Start and Reset contact inputs allow easy integration into industrial machines and electrical control panels.
