(Unit: mm)

 

Rating

• *1 When the power supply voltage is 24 V DC, there is an inrush current of approx. 0.25 A. Therefore, care must be taken when the power supply of the main body of the timer is switched for a non-contact output, such as a sensor.
• *2 The ripple of DC power supply is 20% or less.
• *3 Refer to the catalog for reference power consumption at DC.
• *4 The control output is the rating of Type H3DK starter. When using 2 or more units in a row, refer to "Relationship Between Mounting Interval and Output Switching Capacity" in the catalog.

Conditions for obtaining CCC

Relationship between the mounting interval of 2 or more H3DK units and the output switching capacity (reference value)

See the figure below for the relationship between the mounting interval and the load current.
Note that using the timer under higher load conditions may shorten the lifespan of internal components due to temperature rise inside the timer.

Test method

• *1. For terminal connections,use a single wire of 2.5 mm^2 or less or bar terminals with insulation sleeves.
• To ensure the withstand voltage after connection, set the length of the exposed conductive portion to be inserted into the terminal to 8 mm or less.
• *2. Screw tightening torque / recommended torque: 0.49 N⋅m, maximum torque: 0.98 N⋅m max

For single wires of 2.5 mm^2 or less

For bar terminals with insulation sleeves

Cautions

• * There is a risk of ignition or explosion due to arcing or heat generation in the relay caused by opening and closing. Do not use in an atmosphere of flammable or explosive gases.
• * The H3DK series has a power supply transformer-less system. Note that you may get an electric shock if you touch the input terminal while the power supply is applied.
• * The inrush current differs depending on the type of load, which affects the opening and closing frequency of the contact and the number of times it is used. Check the inrush current together with the rated current, and design the circuit with a margin.
• * The lifespan of the output relay varies greatly depending on the switching capacity and switching conditions, so be sure to use it within the rated load and the number of electrical lifespan cycles, taking into consideration the actual usage conditions. If it is used beyond its lifespan, contact welding or burnout may occur. Be sure to use the load current below the rated value. When using a heater, etc., be sure to use a thermo switch in the load circuit.
• * Do not remove the outer case.
• * Mild electric shock, fire, and equipment failure may occur in rare cases. Do not disassemble, modify, repair, or touch the inside.
• *For product information other than the above, refer to the catalog.
