DS2413 − Dual Channel Addressable Switch
Dual Switch
3A [.]XXXXXXXXXXXX[XX][/[ PIO.[A|B|ALL|BYTE] | sensed.[A|B|ALL|BYTE] | ]]
3A
read-write,
yes-no
State of the open-drain output ( PIO ) pin. 0 =
non-conducting (off), 1 = conducting (on).
Writing zero will turn off the switch, non-zero will turn on
the switch. Reading the PIO state will return the
switch setting. To determine the actual logic level at the
switch, refer to the sensed property.
ALL references both channels simultaneously, comma
separated.
BYTE references both channels simultaneously as a single
byte, with channel A in bit 0.
read-only,
yes-no
Logic level at the PIO pin. 0 = ground. 1 = high
(˜2.4V - 5V ). Really makes sense only if the
PIO state is set to zero (off), else will read zero.
ALL references both channels simultaneously, comma
separated.
BYTE references both channels simultaneously as a single
byte, with channel A in bit 0.
Use the set_alarm property to set the alarm triggering criteria.
The DS2413
(3) allows control of other devices, like LEDs and
relays. It differs from the DS2405 with a cleaner
interface and two channels The DS2413 also has two
channels like the DS2406 and DS2407 but has no
memory, and no alarm. There is also varying types of switch
and sensing in the DS2408, DS2409, LCD, DS276x,
DS2450.
Unique among the switches, the DS2413 can switch
higher voltages, up to 28V.
