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 module + tracking O/V + screw terminals
b. W2TF: - W2 module + tracking O/V + fastons
c. W2FS: - W2 module + fixed O/V + screw terminals
d. W2FF: - W2 module + fixed O/V + fastons
2. Programmable Module Options.
2.1 Options: -
a. V1: - 0-5v programming + inhibit
b. V2: - 0-5v programming + current programming + inhibit
c. V3: - 0-5v programming + enable
d. V4: - 0-5v programming + current programming + enable
e. R1: - 0-32k resistive programming + inhibit
f. R2: - 0-32k resistive programming + current programming + inhibit
g. R3: - 0-32k resistive programming + enable
h. R4: - 0-32k resistive programming + current programming + 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 0-32kΩ external resistance connected between pin 6
and pins 1-3 results in a linear 0.25-7.5 volt output (1kΩ/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.
