Highly Reliable, 4-pole Miniature Relay Ideal
for Sequence Control
• Card lift-off employed for greater life and stable quality.
• Long endurance and stable quality are assured by card lift-off
system.
• Mounting interchangeability with MY-series Relays.
• Operation indicator mechanism incorporated for at-a-glance
monitoring of ON/OFF operation. In addition, a built-in operation
indicator model is also included in this Relay Series.
The arc barrier equipped model is
a relay designed to prevent arc
short-circuiting between phases
and can be used in a circuit which
has potential difference between
phases. The switching power of
such a circuit with potential difference must be limited to less than
1/2 the rated load when using this
Relay.
The built-in diode model is a relay
which incorporates a diode for absorption of the reverse voltage
that may be generated when the
coil is de-energized. Because the
release time of this model is longer than the standard model, pay
adequate attention to this point in
designing a circuit. Also, pay attention to the + polarity of the coil.
The reverse-breakdown voltage
of the diode is 1,000 V.
The built-in operation indicator
model has a newly added operation indicator to the conventional
operation indication mechanism
and facilitates operation monitoring without being affected by ambient illumination.
With the -N model (rated at 16,
12, 24, and 48 VDC) and -N1
model rated at 6, 12, 24, 48, and
100 VDC), pay attention to the +
polarity of the coil.

Note: 1. The PYF@A-TU is a high-humidity relay with nickel-plated rustproof terminal screws that are the same as the PYF@A in size.
2. The PYF14T is slightly different from the PYF14A(-TU) in shape and size.
3. The PYF@A-E is a finger-protection model, for which round terminals are not available. Use fork-shaped terminals or equivalent ones
instead.

Precautions
Refer to page 11 for general precautions.
A DC coil model with a built-in indicator or built-in diode has coil
polarity. Be sure to wire the terminals correctly, otherwise the diode
may be broken or the operating indicator may not be lit. Furthermore,
as a result of the short-circuiting of the built-in diode, the devices in
the circuit may be damaged.
