The
Quad Relay Controller is a remotely operated device that can be used
for activating up to four separate electrical circuits. The
controller has
four onboard relays, each with 10A contacts (limited to 5A by board
traces). These
are Form C relays having normally-open, normally-closed & common
contacts.
Each relay is invidually controllable by one of four external switch
closure inputs. To implement a switch closure input, simply apply
a length of 2-conductor wire such as telephone cabling or speaker wire
and connect a normally-open switch of your choice. (Suitable
switches include reed, pushbutton, rotary, toggle, etc.)
The controller also accepts serial
host commands from a microcontroller. (Additional purchase options include USB, RS-232, and RF
wireless.) The following control
methods are
provided in the standard product:
- External
switch closure (x4)
- Microcontroller
TTL USART command
In addition,
the following purchase options are available:
- USB host
(option)
- RS-232
host (option)
- Wireless
RF keyfob (option)
- Plastic
enclosure (option)
The controller
device
can be used in a variety of applications:
- Robotics
- Industrial
control
- Animatronics
- Security
- Medical
devices
- and more!
To support a variety of applications, we offer several
control options listed below:
- USB (includes 6-foot cable
with type 'A' connector)
- RS-232 (requires 9-pin serial
cable, not included)
- Wireless
RF (includes keyfob transmitter with battery)

Serial Host Commands:
When using a serial communications method (TTL USART, USB option,
or RS-232 option), the host may issue commands for relay control.
You may use a terminal emulator program such as HypterTerminal or
Docklight to issue commands. Alternatively, a custom developed
application may also be used. Available commands are listed below:
- RONn [ttt] --Activate
relay [n = 1,2,3,4] [ttt=duration (secs)]
- RON! [ttt] --Activate all relays
- ROFn
--Deactivate relay [n = 1,2,3,4]
- ROF!
--Deactivate all relays
- GETn
--Get relay state [response = "OFF" or "ON"]
Each command
to the controller must be terminated with a carriage return (13)
character. (Responses from the controller will also be
appropriately terminated.) "OK\r" is returned by the
controller in response to a valid relay activation or deactivation
command. The following examples illustrate
proper command usage:
- RON2\r --
Activate
relay #2
- ROF2\r --
Deactivate relay #2
- RON2 025\r -- Activate relay #2 for
25
seconds, then deactivate
- GET2\r -- Get
activation state for relay #2
