Datasheet

COO (Country of Origin):: CN

Omron H3DT Series Timer Relay, 0.1 s-1200 h Time range, DPDT Contact configuration - H3DT-L2 24-240VAC/DC

This timer relay provides adjustable timing control for automation and control panels, offering a Compact DIN-rail mounting solution for timed switching in industrial environments. It accepts a broad supply range and is designed for multifunction timing tasks where configurable delay and repeat behaviours are required.

Features and Benefits:

• DPDT contacts rated for 5A enable reliable circuit switching
• Wide supply range 24–240V AC/DC supports mixed-voltage systems
• Timing span 0.1s–1200h allows short pulses to long delays
• Dial adjustment gives Rapid on-site time setting
• Screw terminals ensure secure conductor retention under vibration
• IP20 and IP30 protection classes suit enclosed installations

Applications

• Suitable for sequencing control in manufacturing lines
• Ideal for pump and motor start/stop delay functions
• Used with relay logic panels in building services controls
• Can be used for timed signalling in marine and offshore electrical racks
• Used for interval control in conveyor systems

What contact arrangement does it use and how many switching points are available

It uses two changeover contact sets providing four switching poles for independent circuits.

How is it mounted and connected within control equipment

It clips onto a DIN rail and connects via screw terminals to maintain firm electrical terminations.

What environmental temperature range will it operate within

It operates between -20°C and 60°C, suitable for typical indoor industrial locations.

Which standards and recognitions relate to its design and safety

It conforms to multiple international approvals including UL508, EN61812-1 and RoHS.

What is the maximum switching voltage and how does that affect load selection

The switching voltage is 250V, which should be matched to the voltage rating of the connected loads.
