Function
The module is disabled by a high logic level applied to this pin.
Reset output (GS-R405S only).
DC input voltage. Recommended maximum voltage is 46V.
Return for input voltage source.
100kHz oscillator output. To be connected to Sync (pin 6) input if the unit is a master and
left open if it is a slave (GS-R400VB only). See fig. 5.
Synchronization input. To be connected to the Oscillator output (pin 5) of the master (GS-
R400VB only). See fig. 5.
A resistor ( 2.2k ) connected from this pin to pin 9 sets the current limiting level
(GS-R400VB only).
Return for output current path.
Internally connected to pin 4.
Senses the remote load return. Must be tied to pin 8 when the remote sensing feature is
not used. See fig. 1.
Senses the remote load high side. Must be tied to pin 11 when the remote load sensing
feature is not used. See fig. 1.
Regulated DC output voltage.
A resistor ( 18k ) connected between this pin and pin 10 sets the output voltage
(GS-R400V and GS-R400VB only).
