Cautions regarding the protection element
1. Part numbers without protection
elements
1) 12 V models
When connecting a coil surge protection
circuit to these relays, we recommend a
Zener diode with a Zener voltage of 24 V
or higher, or a resistor (680 to 1,000 ).
When a diode is connected to the coil in
parallel, the release time will slow down
and working life may shorten. Before use,
please check the circuit and verify that
the diode is not connected in parallel to
the coil drive circuit.
2) 24 V models
When connecting a coil surge protection
circuit to these relays, we recommend a
Zener diode with a Zener voltage of 48 V
or higher, or a resistor (2,800 to
4,700 ).
When a diode is connected to the coil in
parallel, the release time will slow down
and working life may shorten. Before use,
please check the circuit and verify that
the diode is not connected in parallel to
the coil drive circuit.

Change of pick-up and drop-out voltage
2. Part numbers with diodes
These relays use a diode in the coil surge
protection element. Therefore, the
release time is slower and the working life
might be shorter compared to part
numbers without protection elements and
part numbers with resistors.
Be sure to use only after evaluating under
actual load conditions.
3. Part numbers with resistors
This part number employs a resistor in
the coil surge protection circuit; therefore,
an external surge protection element is
not required. In particular, when a diode
is connected in parallel with a coil, the
revert time becomes slower which could
adversely affect working life. Please
check the circuit and make sure that a
diode is not connected in parallel with the
coil drive circuit.
