Power
consumption
H3DK-F At 240 VAC: 4.5VA max. *3
H3DK-FA At 12 VDC: 0.6 W max.
Control output Contact output (SPDT): 5 A at 250 VAC with resistive load (cosΦ = 1), 5 A at 24 VDC with resistive
load *3, *4
Ambient operating temperature -20 to 55°C (with no icing)
Storage temperature -40 to 70°C (with no icing)
Ambient operating humidity 25% to 85%

 

*1.When using a 24-VDC power supply voltage, there will be an inrush current of approximately 0.25 A. Allow for this inrush current when turning ON and OFF the power supply to the Timer with device with a solid-state output, such as a sensor.

*2.DC ripple: 20% max.

*3.Refer to DC Power Consumptions (Reference Information) on Data Sheet for DC power consumptions.

*4.The control output ratings are for one H3DK operating alone. If you operate two or more Timers side by side, refer to Installation Pitch and Output Switching Capacity (Reference Values) in the below.

*5.125 VDC: 0.15 A max. with resistive load, 125 VDC: 0.1 A with L/R of 7 ms.
Minimum load: 10 mA at 5 VDC (P level, reference value)
