Ordering Information
■List of Models
Note: 1. Sockets and Hold-down Clips are not included with the H3YN. They must be ordered separately.
2. Only models with 24-VDC power supply are available.
3. Use the H3YN-4 or H3YN-41 Series when switching micro loads, and use the H3YN-4-Z or H3YN-41-Z Series when switching even
smaller loads.

■Ratings
Note: 1. Do not use the output from an inverter as the power supply. Refer to Safety Precautions for All Times for details.
2. Single-phase, full-wave-rectified power supplies can be used.
3. When using the H3YN continuously in any place where the ambient temperature is in a range of 45°C to 50°C, supply 90% to 110% of
the rated supply voltages (supply 95% to 110% with 12 VDC type).
4. Set the reset voltage as follows to ensure proper resetting.
100 to 120 VAC: 10 VAC max.
200 to 230 VAC: 20 VAC max.
100 to 110 VDC: 10 VDC max.
5. Refer to Safety Precautions for All Timers when combining the Timer with an AC 2-wire proximity sensor.
6. A diode to prevent reverse voltages is provided only on models with a DC power supply.

Safety Precautions
Refer to Safety Precautions for All Timers.
Warning Indications
Meaning of Product Safety Symbols
Risk of fire and explosion due to arcing and relay heat
generation that accompanies switching. Do not use in an
environment where flammable or explosive gas is present.
The service life of the output relay varies widely
depending on switching capacity and switching
conditions. Use only within the rated load and
electrical life count, based on actual conditions of use.
Risk of contact sticking and burning if used past the
service life. Always use a load current that does not
exceed the rating, and if a heater is used, use a thermal switch in the
load circuit.
Do not remove the outer casing.
In rare circumstances there is a risk of slight electrical
shock, fire, or device damage. Do not disassemble,
modify, repair, or otherwise touch the inside.
Tighten the screws for the lead wires to the Socket to
the following torque.
PYF Socket: 0.78 to 1.18 N·m
This is the recommended range when crimp terminals
are used.
If the screws are not tightened sufficiently on Front-
connecting Sockets, the lead wires may come off, connection failure
may cause abnormal heating, or fires may occur.
If they are tightened excessively, the screw threads may be
damaged.
Adverse operating environments may accelerate the deterioration of
the setting dial, LEDs, and resin parts, possibly resulting in malfunc-
tion or display defects. Perform periodic inspections and part
replacements.
We recommend that you use a surge absorber if surge voltages may
occur.
When you dispose of the Timer, do so according to all local ordi-
nances for processing industrial waste.
The operating voltage will increase when using the H3YN continu-
ously in any place where the ambient temperature is in a range of
45°C to 50°C. Supply 90% to 110% of the rated voltages (at 12 VDC:
95% to 110%).
Do not leave the H3YN in time-up condition for a long period of time
(for example, more than one month in any place where the ambient
temperature is high), otherwise the internal parts (aluminum electro-
lytic capacitor) may become damaged. Therefore, the use of the
H3YN with a relay as shown in the following circuit diagram is recom-
mended to extend the service life of the H3YN.
The H3YN must be disconnected from the Socket when setting the
DIP switch, otherwise the user may touch a terminal imposed with a
high voltage and get an electric shock.
Do not connect the H3YN as shown in the following circuit diagram
on the right hand side, otherwise the H3YN’s internal contacts differ-
ent from each other in polarity may become short-circuited.
Use the following safety circuit when building a self-holding or self-
resetting circuit with the H3YN and an auxiliary relay, such as an MY
Relay, in combination.
In the case of the above circuit, the H3YN will be in pulse operation.
Therefore, if the circuit shown on page 6 is used, no auxiliary relay
will be required.
Do not set to the minimum setting in the flicker modes, otherwise the
contact may become damaged.
Be careful not to apply any voltage to the terminal screws on the
back of the Timer. Mount the product so that the screws will not come
in contact with the panel or metal parts.
Do not use the H3YN in places where there is excessive dust, corro-
sive gas, or direct sunlight.
Do not mount more than one H3YN closely together, otherwise the
internal parts may become damaged. Make sure that there is a
space of 5 mm or more between any H3YN models next to each
other to allow heat radiation.
CAUTION Indicates a potentially hazardous situation
which, if not avoided, may result in minor
or moderate injury or in property damage.

The internal parts may become damaged if a supply voltage other
than the rated ones is imposed on the H3YN.
In order to conform to UL and CSA requirements when using the
H3YN-4/-41 or H3YN-4-Z/-41-Z, connect the Unit so that output con-
tacts (contacts of different poles) have the same electric potential.
In cases such as PLC input where the load is extremely small for the
control output of a timer containing a power relay (using other than
gold-plated contacts), reliability can be increased by using contacts
of the same poles (e.g., the H3Y-2) in parallel.
Always use the same type of wire.
Installation
There are no restrictions on the installation orientation.
Install the Timer securely.
Precautions for EN61812-1
Conformance
The H3YN as a built-in timer conforms to EN61812-1 provided that
the following conditions are satisfied.
Handling
Do not touch the DIP switch while power is supplied to the H3YN.
Before dismounting the H3YN from the Socket, make sure that no
voltage is imposed on any terminal of the H3YN.
The applicable Socket is the PYF@A.
Only basic insulation is ensured between the Y92H-3 Hold-down
Clips and H3YN internal circuits.
Do not allow the Y92H-3 Hold-down Clips to contact other parts.
The insulation test voltage between different pole contacts for the 4-
pole model is the impulse voltage of 2.95 kV.
Wiring
The power supply for the H3YN must be protected with equipment
such as a breaker approved by VDE.
Basic insulation is ensured between the H3YN’s operating circuit and
control output.
Basic insulation: Overvoltage category II,
pollution degree 1 (H3YN-4/-41, H3YN-4-Z/-
41-Z), pollution degree 2 (H3YN-2/-21)
(with a clearance of 1.5 mm and a creepage
distance of 2.5 mm at 240 VAC)
