Product Description:
Series Overview
The H3DK and H3DKZ series consist of compact solid-state timers designed for DIN rail mounting. These electronic timers are ideal for use in cabinet and machine control systems. With a slim profile measuring just 22.5 mm in width, they are perfectly suited for installation in densely packed control panels.
These timers offer a comprehensive range of timing functions to meet various application needs. Available options include single ON-delay, multifunction timers with 8-mode and 4-mode settings, twin flicker for asymmetric cycling, and star-delta motor starting functions. Relay output configurations include SPDT (single pole double throw) and DPDT (double pole double throw) types. Selected models also feature additional capabilities such as a voltage start input or a switchable time-limit with instantaneous contact.
The series is designed to support a broad supply voltage range from 24 to 240 VAC/DC, with certain models further offering options for 12 VDC and 240 to 440 VAC. They cover a wide timing scale, spanning from as short as 0.1 seconds up to 1200 hours, which allows the entire family to accommodate tasks involving brief pulses, extensive delays, and everything in between.
For clear operational feedback, the timers are equipped with green LEDs indicating power and operation status, along with orange LEDs to indicate output status. Safety is prioritized through finger-safe screw terminals that use captive screws and comply with the EN 50274 standard, ensuring secure and safe wiring in all installations.

Applications:
Motor Control
This category includes methods for starting motors with reduced voltage, such as star-delta (also known as wye-delta) starting techniques. It also covers the management of start-up delays for pumps, fans, compressors, and conveyors. Additionally, it involves motor interlock mechanisms along with timing for run-on operations to ensure smooth motor control.
Sequence & Process Control
Sequence and process control entails implementing ON-delay and OFF-delay switching within machine sequences to optimize operations. This includes generating interval pulses and one-shot output signals as well as establishing signal-triggered ON/OFF delay loops. The control processes are crucial for managing heating, lighting, and auxiliary circuit sequencing effectively.
Signaling & Alarm
In signaling and alarm systems, techniques are applied such as flashing warning lights and cycling signal towers to alert users. Buzzer and alarm systems often utilize intermittent operation patterns. Additionally, these systems provide pulsed or intermittent outputs that feed indicators and sirens to enhance safety and notification capabilities.
Building, HVAC & Utilities
Control applications in building, HVAC, and utilities include managing ventilation, air-conditioning, and lighting with precise delay controls. The timing of valve and pump cycling is essential in water treatment and irrigation systems. Moreover, equipment such as elevators and escalators, along with auxiliary devices, rely on accurate timing mechanisms for optimal operation.
OEM Machinery & Panels
This area focuses on control panels for OEM machinery used in packaging, textile, printing, and machine-tool industries. It involves general-purpose automation solutions and serves as a replacement for traditional relay systems. Furthermore, it supports the retrofit and maintenance of existing H3DK and H3DKZ installations to ensure continued reliability and performance.
