Input Connections
Signal Inputs
Connect thestartinput contact between terminals
C
and
F
,thereset
input contact between terminals
C
and
G
, the gate input contact be-
tween terminals
C
and
E
, and the check input contact between ter-
minals
C
and
D
.
For each signal input contact, use a gold-plated contacts with high
reliability. Be sure that these input signals satisfy the following re-
quirements:aresistanceof1k
$
(max.) andaresidual voltageof1V
(max.) when the contact is made.
Solid-state Signal Inputs
Connect the start input transistor between terminals
C
and
F
,there-
set input transistor between terminals
C
and
G
, the gate input tran-
sistorbetween terminals
C
and
E
, andthe check input transistorbe-
tween terminals
C
and
D
.
For signal input, use an open collector type transistor with charac-
teristics:V
CEO
=20Vmin.,V
CE(S)
= 1 V max., IC = 50 mA min. and
I
CBO
=0.5
&
A max. In addition, be sure that the input signals satisfy
the following requirements: a resistance of 1 k
$
(max.) and a resid-
ualvoltageof 1V (max.) when thetransistor is ON, andaresistance
of 200 k
$
(min.) when the transistor is OFF.
