The H3DK-F 24-240AC/DC is a low cost and high-performance timer designed by Omron. This timer is based on Omron's Proportional Timer Technology, which delivers a highly accurate and mathematically repeatable timing solution that is accurate within ± 0.03%. This timer has a wide variety of features, including a 2-step output, 1, 3/2/1 cycle control, forced trigger of an output when the power is restored, and a latency-free or immediate triggering of an output after a trigger is received. The H3DK-F 24-240AC/DC is also able to store up to 512 timer programs, each of which includes a maximum of 16,000 cycles. Additionally, users have access to a wide range of external and internal I/O, including real-time clock and motion control inputs, analog and serial RS232/RS485 inputs, and Ethernet TCP/IP. This timer is suitable for a wide range of applications, from HVAC control to automotive production.
