Product Description:
The H3DKZ-F is a DIN rail-mounted twin flicker timer from the Omron H3DKZ series, 22.5 mm slim width. Independent dials set the ON and OFF times, producing adjustable flashing or cycling patterns; a front switch selects OFF start or ON start. It suits replacement and maintenance of existing H3DKZ-F circuits.
Key features:
- Twin flicker function: OFF start or ON start selectable
- Independent ON time and OFF time setting
- 8 timing ranges from 0.1 s to 1200 h
- SPDT (1c) relay output, 5 A @ 250 VAC resistive load
- 24-240 VAC/DC supply; 12 VDC version (FA) available
- Separate ON and OFF output indicators
- 35 mm DIN rail mounting, 22.5 mm slim profile
Accuracy of operating time +/-1% FS max.; mechanical life 10,000,000 operations min.; electrical life 100,000 operations min. at 5 A @ 250 VAC. Operating temperature -20 to +55 C, protection IP30 (terminal block IP20).
Typical applications: flashing warning lights and signal towers, buzzer/alarm cycling, pulsed output, intermittent pump or valve operation, indicator and traffic flashing, replacement of aging H3DKZ-F timers in panels and field maintenance.

Applications:
Motor Control
This category encompasses methods such as star-delta (also known as wye-delta) reduced-voltage motor starting techniques. Additionally, it includes managing delayed start-up sequences for pumps, fans, compressors, and conveyors. There is also a focus on motor interlock mechanisms and run-on timing to ensure safe and efficient operation.
Sequence & Process Control
Sequence and process control involves utilizing ON-delay and OFF-delay switching within machine operation sequences. It also covers generating interval pulses and one-shot output signals for precise control. Signal-triggered ON/OFF delay loops are implemented to respond dynamically to system inputs. This control extends to the sequencing of heating, lighting, and auxiliary circuits to optimize performance.
Signaling & Alarm
Signaling and alarm systems include features like flashing warning lights and the cycling of signal towers to attract attention. The operation of buzzers and alarms in an intermittent manner is also managed within this area. Furthermore, pulsed or intermittent outputs are used for indicators and sirens to ensure timely alerts.
Building, HVAC & Utilities
In building management, HVAC, and utility applications, delay control is applied to ventilation, air conditioning, and lighting systems. The cycling of valves and pumps is important for water treatment and irrigation processes. Timing control is also critical for elevators, escalators, and various auxiliary equipment to maintain functionality and safety.
OEM Machinery & Panels
This field covers control panels designed for packaging, textile, printing, and machine tools. It emphasizes general-purpose automation as well as relay replacement. Additionally, it includes the retrofit and maintenance of existing H3DK and H3DKZ system installations, ensuring continued reliability and performance.
