Datasheet

Omron H3DT Series Timer, 1 to 120s Time Range, 100V AC Supply Voltage - H3DT-HCL 100-120VAC

This timer is a DIN-rail mounted time relay designed for industrial control and automation panels, providing selectable delay timing for switching tasks in electrical systems. It accepts AC or DC supplies and offers an adjustable timing window suitable for sequential control, interlocking and delay-based operations in factory and building installations.

Features and Benefits:

• 1-120s timing range enables fine control of delay intervals
• SPDT contact arrangement allows changeover switching between circuits
• Push-in terminals speed installation and reduce wiring time
• 5A contact rating supports moderate load switching tasks
• 100VAC-120VAC and 240VDC supply options suit varied power architectures
• IP30 protection rating offers Basic panel dust defence

Applications

• Suitable for sequence control in conveyor and material-handling systems
• Used for interlock timing on motor starter circuits
• Ideal for delay functions in HVAC control panels
• Can be used for timed lighting control in industrial facilities
• Used with relay logic for safety timing and reset sequences

What Terminal style does it use for connection and what is the benefit?

It uses push-in terminals which permit tool-free conductor insertion, reducing assembly time and improving consistency during wiring.

How does the contact configuration affect wiring options?

The SPDT configuration provides a common output that can switch between normally open and normally closed circuits, enabling alternative routing without extra relays.

What environmental temperatures can it operate within?

The device is rated for operation from -20°C up to 60°C, allowing use across typical indoor industrial temperature ranges.

Which standards and approvals are relevant for integration into control panels?

It carries multiple approvals including UL 508 and EN 61812-1, facilitating incorporation into systems that require recognised safety and performance assessments.

What switching voltage and current constraints should installers observe?

The maximum switching voltage is 250VAC and contact current is 5A, so loads should be selected or interfacing devices used accordingly.
