ENDA EM4401-230 is an industrial digital memory timer with an LCD display and 230V AC supply, designed for machinery, control panels and automation processes requiring accurate and flexible timing control.

Its compact 48x48 mm panel format and 2 x 4 digit LCD display make it suitable for machine control panels where both space and clear timer indication are important.

A major advantage of the EM4401 is its selectable PNP or NPN sensor input, allowing the timer to be integrated with a wide range of industrial sensors and control systems.

External control inputs include:

• Start
• Gate
• Reset

PNP or NPN input operation is selectable through programming, while minimum input ON and OFF pulse times can be adjusted from 1 ms to 100 ms.

Wide timing range

The EM4401 provides 9 selectable timing ranges, covering applications from 0...99.99 seconds up to 0...9999 hours.

The unit also offers:

• Up counting;
• Down counting;
• Memory function;
• 12 different output operating modes;
• Adjustable display brightness;
• Three-level parameter access protection.

Control outputs

The timer provides two control relay outputs:

• OUT1: 250V AC, 2A, NO + NC
• OUT2: 250V AC, 2A, NO

Compatible configurations also support open collector outputs up to 30V DC / 50mA. A 12V DC, maximum 50mA auxiliary supply is available for compatible sensors.

The manufacturer's specified timing accuracy is +/-0.01% +/-1 ms, supporting repeatable timing in industrial machine cycles.
