Multi-range, Multi-mode Timer H3DK-M / -S

DIN Track-mounted, 22.5-mm-width Standard Timer Series

 

Features :

Multiple time ranges and operating modes let you cover a wide range of applications.

The time-limit DPDT output contacts can be changed to time-limit SPDT and instantaneous SPDT output contacts using a switch.

Sequence checks are easily performed by setting an instantaneous output to 0.

Start signal control for the H3DK-M.

*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.The power consumption is for mode A after the Timer times out.
For the H3DK-M[], the maximum power consumption is given, including the current consumed by the input circuit.

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

*5.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.

*6.125 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)

Installation Pitch and Output Switching Capacity (Reference Values)

The relation between the installation pitch and the load current is shown in the following graph. (Except for the H3DK-GE)
If Timer is used under load conditions that exceed the specified values, the temperature inside the Timer will increase, reducing the life expectancy of internal parts.

I/O

 


Model H3DK-M1/-M2 H3DK-S1/-S2
Input Start Functions to start timing. There is no start input.
Output Control output The output is turned ON/OFF according to the operating mode when the value that is set on the dial is
reached. *

 

*If the INST/TIME switch on the front of the Timer is set to INST on the H3DK-M2/-S2, relay R2 will operate as instantaneous contacts and will turn ON/OFF in synchronization with the power supply.*If the INST/TIME switch on the front of the Timer is set to INST on the H3DK-M2/-S2, relay R2 will operate as instantaneous contacts and will turn ON/OFF in synchronization with the power supply.
