ReviewsThis board is helpful for connecting digital systems (like a 5V microcontroller) to a high-voltage or noisy system. This board electrically isolates a controller from the high-power system by use of an opto-isolator IC.
This IC has four LEDs and four
photodiodes built-in.
This allows the low-voltage side to
control a high voltage side
We often use this board to allow a
microcontroller control servos
or other motors that use a higher
voltage than the TTL logic on the (3.3V or 5V) micro,
and may cause electromagnetic
interferance with our system as the motors turn on and off.
This board will isolate the
systems, creating a type of electrical noise barrier between devices
This breakout board uses the TLP281
optoisolator and discrete transistors to correct the logic.
Comes with four channels.
Great for use in noisy circuits
where signal lines require electrical isolation
A normal LED opto-isolator will
invert the logic of a signal.
We threw some transistors on this
compact board to correct the inversion.
What you put into the IN pins, will
be replicated on the the OUT pins, but at the higher voltage (HV)
Features:
Use of low level control high
level.
Such as the use of single chip
microcomputer 3V or 5V voltage 9V or 12V voltage control
HVCC maximum not more than
24V.
Outlet OUT1 / OUT2 / OUT3 / OUT4
output current is equal to the largest HVCC / 5.1K,
maximum absorption current
500mA
Input: IN1 / IN2 / IN3 / IN4, SCM
or for Arduino IO port,
GND with single-chip microcomputer
or for Arduino board GND connection.
IN1 / IN2 / IN3 / IN4 respectively
control the OUT1 / OUT2 / OUT3 / OUT4
Output: OUT1 / OUT2 / OUT3 / OUT4
Output: HVCC: Connection is control
of high voltage anode,
HGND connection is control of high
voltage anode
PCB Size: 25*24mm/0.98*0.94
Package Included:
1 x 4-Channel Opto-isolator IC Module for Arduino High and Low level Expansion Board
