Cautions regarding the protection element
1. Part numbers without protection
elements
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. 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.
For Cautions for Use, see Relay Technical Information.
