Section 11 - Wide Range Programmable Modules
W2 Programmable Module
1.1 The
single slot module
W2
has a range of
0.25-7.5V DC
with a current capability of
30 amps
.
1.2 The
W2
Module
must
be fitted with any one of the control options listed in section. 2.1.
1.3 Select one of the following when designating the baseboard required: -
a.
W2TS
: - W2 tracking O/V + screw terminals
b.
W2TF
: - W2 tracking O/V + fastons
c.
W2FS
: - W2 fixed O/V + screw terminals
d.
W2FF
: - W2 fixed O/V + fastons
2. Programmable Module Options.
2.1 Options: -
a.
V1
: -
0-5v progr inhibit
b.
V2

0-5v progr current progr inhibit
c.
V3
: -
0-5v progr enable
d.
V4
: -
0-5v progr current progr enable
e.
R1
: -
0-32k resistive progr inhibit
f.
R2
: -

g.
R3
: -
0-32k resistive progr enable
h.
R4
: -
0-32k resistive progr current progr enable
2.2 Options brief description: -
a.
Subscript V
: - voltage programming, a
0-5 volt
input from an external DC source, connected
between
pin 4
(+ 0-5V) and
pins 1-3
(0V) results in a linear
0.25-7.5
volt output.
b.
Subscript R
: - resistance programming, a
0-32k
Ω
external resistance connected between
pin 6
and
pins 1-3
results in a linear
0.25-7.5
volt output
(1k
Ω
/0.234 volts)
.
c.
Digits 1-4
: - combinations of additional options including
programmable current limit
and
Inhibit
or
Enable
see
figure 4
for further details. The programmable current limit requires a
0-5
volt
input from an external DC source, connected between
pin 5
(+ 0-5V) and
pins 1-3
(0V)
results in a linear current limit
0.8-30 amps
.
