Datasheet

Omron H3DK Series Timer Relay, 100/120V AC Supply Voltage, 1 to 12s Time Range - H3DK-HCS 100-120VAC

This timer relay provides timed switching control for industrial and control-panel environments, designed for DIN-rail mounting and electrical automation interfaces. It accepts AC supply voltages around 100–120V and has DC supply compatibility across a wide range, enabling integration with varied control systems while offering a single timed contact for sequencing and delay functions.

Features and Benefits:

• Single changeover contact rated for 5A protects downstream circuits
• Dual time ranges of 1 to 12 s and 0.1 to 1.2 s suit coarse and fine timing
• Switching capability up to 250V AC supports common load voltages
• Screw Terminal connections ensure secure wiring and easy servicing
• Operating ambient span −20 to 55°C allows use in varied temperature conditions
• Compact width 22.5mm saves rail space in crowded panels

Applications

• Suitable for sequence delays in assembly-line automation
• Ideal for timing inputs to PLCs and control modules
• Used for pump and motor start/stop sequencing
• Can be used for conveyor indexing and dwell control
• Suitable for control panels requiring small-form-factor timers

What mounting method does it use for panel installation?

It attaches directly to standard DIN rail for Rapid installation and removal.

How many timing functions are available and how are they selected?

It offers a single timing function with two selectable time ranges to cover fast and slow delay needs.

Which approvals cover electrical safety and interoperability?

It holds multiple approvals including EN and North American standards for industrial control equipment.

What Terminal type is provided for field wiring?

Screw terminals are provided to accept standard conductor types for secure connections.

Can it handle DC supply voltages and what span is supported?

It accepts DC supplies across a broad range from 12 to 240V dc for flexible system integration.
