4-Channel USB Relay Controller Board
; Individually configurable I/O channels!
; Compatible with DS18B20 temp sensors!
; USB control for your custom applications!
This professional quality USB relay controller and data acquisition
module allows computer controlled switching of external devices,
plus full bi-directional communication with the external world using
the USB port of your computer. The controller is very flexible and can be
used for a wide range of custom applications, including weather stations,
temperature monitoring, logging and control, etc.
It is compatible with both Windows and Apple OS X, as well as various
Linux flavors. When you plug it into your computer, it appears as
a USB CDC device that creates a Virtual Serial (COM) port allowing easy communication with the board through any programming language that supports serial communications (VB, VB.NET,
C#, C, C++, Perl, Java, etc).
The controller features four onboard relay outputs with a current rating of
10A each. Also onboard is a 6-channel Input/Output interface, with each channel individually configurable as Digital Input, Digital Output, Analog Input (10-bit Resolution), or DS18B20 series
In Digital Input/Output modes, each channel can support a T TL compatible or ST input or a 5V output signal. In
Analog Input mode, each channel can convert a voltage of between 0 to 5V into a 10-bit digital representation.
Finally, in Temperature Sensor mode, each channel can be connected to a DS18B20 series Digital Temp Sensor.
Ultimate 555 Timers
This new series builds on
the classic UT5 kit,
but takes it to a
whole new level!
You can configure
it on the fly with easy-to-use jumper settings, drive
relays, and directly interface all timer functions with
onboard controls or external signals.
All connections are easily made though terminal
blocks. Plus, we've replaced the ceramic capacitor of
other timer kits with a Mylar capacitor which keeps
your timings stable over a much wider range of voltages! Available in through hole or surface mount versions! Visit www.ramseykits.com for version details.

Keyless Entry Test Set
Keyless entry systems are great...
until they don’t work! Now, testing
your system is easy. To test the complete key fob-to-vehicle and vehicle-to-key fob communications path just stand
close to the vehicle with the WCT3 and
your key fob in hand. Press the test button and the WCT3 will detect and display
the presence of the vehicle's 125kHz/20kHz signal
and, if they "handshake", will also detect and display
the presence of your key fob's 315MHz return signal.
You can independently test key fob only signals (panic,
lock, trunk, etc.) by holding the key fob near the
WCT3, pressing the test button, and pushing the function button on the key fob. The same functionality
testing can be done with IR key fobs. Detects 20kHz,
125kHz, 315MHz, and IR. Requires 9V battery.
