The unit can turn the output ON/OFF by dry contact between
Remote ON/OFF and +5-AUX.(Note)
Short (4.5 ~ 5.5V) : Power ON ; Open(0 ~ 0.5V) : Power OFF ;
The maximum input voltage is 5.5V
High (3.5 ~ 5.5V) : When the internal temperature exceeds
the limit of temperature alarm.
Low (-0.5 ~ 0.5V) : When the internal temperature is normal.
The maximum sourcing current is 10mA and only for output.(Note)
The maximum sourcing current is 10mA and only for output.(Note)
The maximum sourcing current is 10mA and only for output.(Note)
The maximum sourcing current is 10mA and only for output.(Note)
Auxiliary voltage output, 4.5~5.5V, referenced to GND-AUX
(pin 4,6,8,10,17,18) only for Remote ON/OFF used. This output
is not controlled by the Remote ON/OFF control.
High(3.5~5.5V):When the fan fail.
Low(-0.5~0.5V):When the fan works normally.

Auxiliary voltage output, 11.4~12.6V, referenced to
GND-AUX (pin17 & 18).
The maximum load current is 1A. This output is not controlled
by “Remote ON-OFF”.
Auxiliary voltage output GND.
The signal return is isolated from the output terV & -V).
Note: Isolated signal, referenced to (GND-AUX).

LED indictor:
Indicate the status of the supply and load condition.
Used to adjust output voltage. The one on the top for fine-tune,
the other for coarse-tune.
Position 4 is an internal termination resistor that prevents signal
rebound for differential signals of CAN bus and Modbus.
Position 1~3 are for device addressing when using communication
interface.
