USB hub powered, modular relay control board.
- Relays (4 x): 5 Amp 30VDC, 5Amp 250V AC
- Sealed omron mechanical relays.
- Command-line application.
- Standard FTDI USB module (dlls for most OSs)
- Power on LED, relay indicator LEDs
* USB cable not included.
The super4 USB relay board is driven over USB directly (not virtual com port). Each board is uniquely identified via its' serial number string, this can be changed using TCTECs RelayMapper application, making replacement of boards easy and programming simple to understand.
For indoor low voltage applications, The Super4 fits inside Jaycar cat: JP6011
A sealed polycarbonate enclosure in an appliance control application.
Using 20mm (22 mm hole) cable gland for the USB plug (fits a type-B plug). Use cable glands of required size for other wiring (example shows 1 for input cable and 1 for output cable).
All glands facing down for water proofing and drainage. Board is tacked in place with silicone, after USB is plugged in and relays wired.
Asheboro Fire Department
I am wanting to sound alarms for secondary dispatch(911 calls). We receive call information through email and will use Microsoft Outlook to make a rule to print the message and activate a relay through usb(an idea) to sound external alarms through-out the fire stations. Does this sound like it will work with the Super4 USB Relay Module, if so, how difficult will it be to setup programming?
The Microsoft outlook rule can be set to 'start application', if the email meets the specified criteria.
The application that is started can be a batch file called 'sound_alarm.bat' with the following line in it:
c:\program files\tctec\relayset.exe -salarm,01 -t10000
The above example will switch on relay one, of the relay board called 'alarm' for 10 seconds.
In this case, relayset.exe is located in C:\program files\tctec\
I tested this example on Microsoft outlook 2007.
Let me know if I can help further.

Question about the Super4. Does the board/switch hold it's state during a power disconnect. For example:
Port 1 = On
Port 2 = Off
Port 3 = On
Port 4 = On
Will these states remain when power is disconnected from the board or will we need to manage the state after accidental power disconnects?
The relays are non-latching, so when power is lost they default to the off (open) position.
The C source code for lrelayset.exe is on our webstite http://www.emx.net.au/page426.htm
It uses the ftdi linux library:http: libftd2xx.so
Alternatively,rather than use the libftd2xx.so library, a compilable C - library is available to interface the FT232RL chip directly. http://www.intra2net.com/en/developer/libftdi/
This has been used to control the super4 under Debian for example.
Note: The super4 uses the FT232RL serial to USB converter in 'bit-bang' mode.
Please let me know if I you any further questions,
