The MR-BusIO-PHOTORELAY is an
experiment board for switching output by
using AQV210E IC, PhotoMOS Relays.
PhotoMOS Relays combined advantage
of solid state relays and mechanical relays
together, so efficient is perfect and better
than other devices. The maximum peak
value at the load is 350V, 130mA for both
AC and DC.
The board can be use with MR-BusIO-
MAIN board or stand-alone. PCB size is
0.63” x 2.80”
The main of the circuit is AQV210E IC.
The internal of the IC consists of LED and
Optoelectronic which use light for
transmission. This make the input and
output totally isolated.
The operation of this board starts when
applying logic HIGH to an I/O pin. The
voltage get divide down to turn on BC547
transistor which then activate AQV210E
PhotoMOS and indicator LED. The current
is then start flowing at the 3-PIN terminal
block.
Please take a look at AQV210E datasheet
for more information.
User can connect output AC or DC load
up to 350V at 130mA. It can control
various types of loads such as relays,
motors, lamps and solenoids.
The MR-BusIO-MAIN is available for
purchase via our website. If you don’t see
the item you need, please contract our
sales department at sales@gravitech.us
• MR-BusIO-MAIN
Experiment board which receives output
signals from any microcontrollers. The
signals then distribute to daughter boards
for each experiment. It designed to
connect directly with 10PIN MRconnect©.
It is a quick and easy way to control up to
8 daughter boards.
