We
have simply perfected the art of controlling relays from the
serial port of a computer or microcontroller. We have
had to. Industry has depended on our controllers for 5 years
now. And in the past 5 years, none of our relay
controllers have been returned due to device failure.
So what makes our R16 better
than the rest? For starters, it switches more current
than any other 16-relay controller in its price range.
It is also smaller in size than
all the other 16-relay controllers we have found. So why
are the others so big? Well, the short answer is that it
is easy to design a large relay controller, but it takes
months of work to hand-route a controller that is physically
no larger than the sum of its components. If you look
carefully at the photograph, there is absolutely no room for
another component, not even a resistor.
A high-end relay controller
needs a brain to match its brawn. Equipped with our new
E3C compliant RS-232 interface processor, you can control 256
relay controllers from a single RS-232 serial port.
That's an amazing 4096 relays from a single serial port.
Perfect for your most demanding computer control applications.
Two banks of 10 LEDs provide
status information about all aspects of the relay controller
board. Two power LEDs indicate that power has been
properly applied to the board. A heartbeat LED is used
to indicate proper operation of the microprocessor. A
data receive LED is used to indicate data has been
received. And finally, 16 LEDs are used to indicate the
status of all 16 relays.
The R16 series relay
controllers are unique in that it supports a simple ASCII
based command set. Using simple ASCII character codes,
you can set the status of an individual relay, a bank of 8
relays, or all 16 relays simultaneously. You can even
ask the board what the current status is of any or all relays.
You can also store and recall
the on/off status of all 16 relays in 256 different memory
banks. This allows you to create simple macros for
making sure certain things are not turned on at the same
time.
And for those mission-critical applications, the
current status of all 16 relays can be stored as the power-up
default. That way, if the board every looses power, it
can activate the relays the way they were before the board
lost power.
Communication is one thing we
spend a lot of time on. And the results of our work are
reflected in the capabilities of our new R16 controller.
The R16 is equipped with a true 15 Kv ESD protected RS-232 transceiver,
capable of generating and accepting user commands at 2400,
4800, 9600, 19.2K, 38.4K, 57.6K, and 115.2K baud. In test mode,
the R16 cycles through the relays and resumes
normal operation at 9600 baud.
The R16 series is available in
three varieties: The R165 is our general-purpose
16-relay controller with sixteen 5-amp relays. The R1610
has sixteen sealed 10-amp relays, making it perfect for
high-current switching applications. It is also recommended
when the controller must be installed in a temperate
environment. If you need a little of both, the hybrid
R1615 is the perfect choice with eight 5-amp relays and eight
10-amp relays.
