Master clock controller for slave clocks

• Will work straight out of the box.
• Gives a 24 V pulse every minute, every 30 seconds, or every second. These voltage pulses are used to drive slave clocks used in institutions like factories, offices, and schools.
• Easy to use Windows program to change pulse interval, pulse length and pulse polarity. No driver installation required. Supported operating systems: Windows 10 / 11.
• Factory calibrated for 1 second accuracy within a month.
• Crystal fine tuning to recalibrate the device if necessary.
• Will produce either unipolar or bipolar (polarity reversing) clock pulses.
• Provides a maximum output current of 500 mA.
• If you have a slave clock using working voltage less than 24 volts, you can calculate the value for the required series resistor here.
