Omron H3DK Series DIN Rail Timer Relay, 2-Contact, 12 V dc, 1 to 120 s, Multifunction-Function, SPDT Switch

This timer relay is a multifunction timing device designed for control panels and automation systems, providing time-delay switching for electrical circuits in industrial environments. It accepts either 240VAC or 12V DC supply and offers selectable timing from 1 to 120s, enabling timed control of loads where single-pole changeover switching is required.

• SPDT contact delivers both make and break switching capability
• 5A contact rating handles moderate control loads reliably
• Multifunction timing offers varied operational modes for flexibility
• DIN rail mounting simplifies installation in control enclosures
• Screw terminals ensure secure electrical connections under vibration
• IP20 and IP30 protection classes suit indoor panel use

• Suitable for sequencing motors and actuators in automation systems
• Ideal for timed control of lighting circuits in industrial facilities
• Used for delay functions in conveyor and material-handling equipment
• Can be used for interlock timing in electrical control panels
• Suitable for replacing or upgrading panel-mounted timers in machinery

It functions across an operating range from -20°C to 55°C, permitting use in many indoor industrial environments.

It provides two contacts configured as a single-pole changeover, allowing one output to switch between two circuits.

The device has a width of 22.5mm, enabling close side-by-side mounting to conserve panel space.

Electrical connections are MADE via screw-type terminals to secure conductors in fixed installations.
