Omron H3DK Series Timer Relay, 1 to 120s Time Range, SPDT Contact Configuration - H3DK-HCL AC100-120

This timer relay provides configurable time-delay functionality for industrial control systems, enabling delayed switching and valve power-off sequencing within automation panels. It is intended for DIN-rail mounting and suits electrical, electronic and mechanical installations requiring Compact time control and a changeover contact for load switching.

Features and Benefits:

• SPDT contact rated for 5A delivers direct load-switching capability
• Multifunction timing covers 1 to 120 s for versatile delay selection
• Accepts 100/120V AC or 24–240V DC supplies for flexible power options
• Screw terminals ensure secure, serviceable wiring connections
• 250V AC switching voltage supports common AC load requirements
• UL508, CSA, EN and IEC standards certification confirms industrial acceptability

Applications

• Suitable for valve power-off delay operations in pneumatic systems
• Ideal for pump and motor control panels requiring timed shut-off
• Used with PLCs for auxiliary timing and interlock sequences
• Can be used for machinery safety delays during stop procedures

What mounting method is required for panel installation?

It clips onto a standard DIN rail to allow Rapid fitting and replacement within control cabinets.

Which environmental limits affect placement inside enclosures?

It operates between -20 °C and 55 °C, so enclosures should maintain ambient temperatures within this range.

How many switching contacts are available for control circuits?

There are two contacts arranged as a single changeover contact providing one switching output.

What protection ratings describe suitability for interior installations?

The product has IP20 and IP30 ratings, indicating protection against finger access and limited solid ingress for indoor use.

How is wiring secured and maintained during service?

Terminals are screw type to permit firm conductor clamping and straightforward retightening during maintenance.
