LANC 8 WATT SERIES REMOTE
ON CONTROL : 3.5 ~ 12V
OFF CONTROL : 0 ~1.2V
ON / OFF CONTROL
REMOTE ON / OFF CONTROL APPLICATION:
Isolated-Closure Remote On/Off
An isolated closure is a closure with both high- and low-impedance states that
sinks current, but does not source current. For on/off control, the closure is
between the ON/OFF pin and VI(–), and can be pro-vided by a device such as a
mechanical switch, an open-collector transistor, or an optoisolator. Figure 1
shows an example of an optoisolator connected. Note that Von/off is defined as the
voltage at the ON/OFF pin with respect to the VI(–) pin. Ion/off is the
current flowing out of the ON/OFF pin.
LANC 8 WATT when Von/off is left isolated to float high, the unit operates, and
when Von/off is pulled low or shorted to VI(–), the unit is off. Table 2 summarizes
the logic levels and module states.

Isolated-Closure Remote On/Off
Table 4 summarizes the electrical specifica-tions for the ON/OFF pin and the
switch for isolated closure positive-logic on/off. In order to satisfy the requirements
for the low-impedance state, the closure must maintain a voltage less than the
maximum logic-low on/off voltage.The logic-high on/off voltage defines the
maximum voltage to which the ON/OFF pin floats when the isolated closure is in
the high-impedance state.The isolated closure must be rated to handle the
logic-low on/off current during its low-impedance state and withstand the logic-high
on/off voltage during its high-impedance state.
