Safety Precautions
Refer to Safety Precautions for All Relays.
The G2AK can be used for special purposes by utilizing its built-in diodes.
When built-in diodes are not required
• With the DC-coil Latching Relay, the built-in diodes become
unnecessary for a circuit in which a coil operating switch is
incorporated for each of the set and reset coils as shown on the
right.
• With the DC/AC-coil Latching Relay, if the junctions between the
set coil and built-in diode and between the reset coil and built-in
diode are connected as shown on the right, only one of the
built-in diode is required and the rest of the diodes become
unnecessary. However, a coil operating switch is required for
each coil. In this case, because of the diode characteristics, the
load rating must be 0.5 A or less.
When built-in diodes are required
• When using the AC-coil Latching Relay which operates on
commercial AC input, the built-in diodes are required.
• With the DC/AC-coil Latching Relay, the built-in diodes are
required for an inductive electrical equipment circuit which
consists of two or more set/reset coils, motor M, general
electromagnetic coil X, etc. per coil operating switch as shown
on the right.
Examples of built-in diode applied circuit
• With the DC-coil Latching Relay, the built-in diode(s) can be
used for surge absorption. in this case, pay attention to the
polarity of the coil. Note that the 5-minute rating applies only to
the set coil rated at 6 VDC and the continuous rating for other
DC coil voltages remains unchanged.
• With the AC-coil Latching Relay, a half-wave rectified power
supply can be obtained as shown on the right. This can be
used as a power supply for light-emitting diodes. However,
because of the diode characteristics, the load rating must be
0.5 A or less.
Note: If a smoothing capacitor is used as shown on the right, the
waveform of the current that flows into the set or reset coil
changes from half wave to that of nearly direct current. In
other words, ripple is improved but the coil temperature
rises, which may adversely affect the set or reset voltage.
Therefore, avoid circuit configuration with an electronic
device which improves ripple, such as a capacitor.
Circuits
Do not allow voltage to be applied simultaneously to both the
set and reset coil. If voltage is applied simultaneously, the
operation will become unstable.
