D26 Series—Type M, DC Multipole with Convertible Contacts
Product Description
Type M, DC multipole
relays are physically and
mechanically similar to
the (D26) Type M AC
relays described on Page
V7-T3-159. They differ only in
the electrical ratings and
available pole combinations
due to the use of a normally
closed late opening, coil
clearing contact, factory
wired to the pickup winding
of the magnet coil. (Contact is
shown as L in figure to the
right.) Magnet coil has built-in
varistor for transient
suppression.
The mechanically latched
relay has one extra contact,
normally open early closing,
factory wired in series with
the winding of the
intermittent rated latch coil.
(Contact is shown as S in
figure to the right.)
Component parts for
these relays are the same
as those listed for the (D26)
Type M AC relays on Page
V7-T3-159, except for the
Indicating Light, which is not
applicable to a DC relay.
Contact poles D26MPR and
D26MPF in 2- to 7-pole relays
are convertible NO to NC or
vice versa. Simply reverse the
terminal screws and rotate
the unit pole 180 ° (in either
direction).
Latch Operation
With the latch coil de-
energized, energizing the
relay coil will pick up the relay
and mechanically latch it in
the pickup position. With the
relay coil de-energized,
energizing the latch coil will
allow the relay to drop out.
