Connection of Reset Input
Model
W
ithout Backup Power for Memory Protection
Connection
of the reset
input contact or an open collector transistor
between
terminals
A
and
C
permits the timer to reset when contact
is made or the transistor turns ON. Use of a high-reliability gold-
plated
contact is recommended for the reset input. For
the reset in

ings:
VCEO
= 20 V min.
IC = 50 mA min.
ICBO
= 0.5

Connection
of the gate
input contact or an open collector transistor
between
terminals
A
and
C
permits the timer to reset when contact
is made or the transistor turns ON. Use of a high-reliability gold-
plated
contact is recommended for the gate input. For the reset in
-
put transistor, select the one satisfying the following electrical rat-
ings:
Gate input contact
(Timer stops when
contact is made.)
Gate input transistor
(Timer stops when
transistor is ON.)

Connection
of the gate
input contact or an open collector transistor
between
terminals
C
and
E
permits the timer operation to be inter
-
rupted
while the contact or transistor is in the ON state. The same
recommendations
as mentioned above apply on the use of the gate
input contact or transistor. Use a gate input contact with a short
bounce time because the contact bounce time causes an error in
the
operate time of the timer for a period equalling the bounce time.
