W type
･In case of standard type (W type), connector + to 1 and –
to 3 according the polarity. WA type connector + to 4
and – to 3 according the polarity.
･For DC voltages other than 12V and 24V,incorrect wiring
will case damage to the surge suppressor.
･The valve with the polarity protection diode be careful
about the allowable voltage fluctuation since a voltage
drop of about 1V.
･There is not ground to the valve of the WA type.

(There is no "S" type because the generation of surge
voltage is prevented by a rectifier.)

Varistor
Note) Surge voltage suppressor of varistor has residual
voltage corresponding to the protective element
and rated voltage ; therefore, protect the controller
side from the surge voltage. The residual voltage of
the diode is approximately 1V.
Y type DIN terminal
･Y type DIN connector conforming to DIN pitch 8mm
standard.
･ D type DIN connector with 9.4mm pitch between
terminals if not interchangeable.
･To distinguish from the D type DIN connector, "N" is listed
at the end of voltage symbol. (For connector parts
without lights, "N" is not indicated. Please refer to the
name plate to distinguish.)
･ Dimension are completely the same as D type DIN
connector.
･When exchanging the pilot valve assembly only. "V115-
□D" is interchangeable with "V115-□Y". Do not replace
V114(G,H,L,M,W) to V115 (DIN terminal), and vice versa.
