8 Relay 8 Analog USB IO Controller 12 V
 
Description: The KTA-225 is a USB or RS485 controlled IO module for interfacing PCs to real world applications, such as controlling lights and sprinkler systems, reading sensors and monitoring switches or analog signals. The Relays are capable of switching up to 5A at 250VAC, 10A at 120VAC and 10A at 24VDC but the PCB tracks will only handle up to about 5A. A simple ASCII protocol allows control from Windows/Mac/Linux using either USB Virtual COM drivers or RS485. Additionally, multiple devices can be connected to one RS485 bus, allowing control of many devices from one USB port.

The KTA-225 has relays with 12 V DC coils and requires an 9 to 15 V DC supply.

This controller is based on the hardware of the KTA-223 controller, but the number of analog inputs has been increased at the cost of the digital inputs. It can be programmed as a stand-alone controller using the free, open source Arduino environment. Internally, the controller is “shield compatible”, allowing the use of many extension boards designed for the Arduino Deumilanove. As shipped the controller is loaded with a sketch or program that receives simple commands over the USB or RS485 serial port and switches relays or responds with the status of the analog inputs.

Multiple controllers can be connected to one or more PCs in an RS485 network. Each controller can be assigned an address and will respond to commands addressed to them.



Features:

  • 8 Relay Outputs 5A 250VAC
  • 8 Analog Inputs (10 bit)
  • Connections via Pluggable Screw Terminals
  • 0-5V 0-3.3V or 0-20mA Analog Inputs, Jumper Selectable
  • 5A Relay Switching
  • Power Indicator LED
  • All enclosed in Professional looking plastic case
  • Arduino Compatible
  • Accepts Arduino Shields (Ethernet / XBee)
  • USB Virtual Serial Port or RS485 Input
  • Easily connect multiple units far apart by RS485

    Missile Switch Cover - Red
     
    Description: It's not what project you have in mind that may use a rocket launch switch... The question is what project will you come up with once you have one in hand? Everyone has a proverbial missile to launch.

    The hot red safety cover protects a toggle switch from accidentally being turned on. When flipped up, the user has full access to a switch underneath. Upon closing the cover, the cover will force the switch arm back into the lower position - a safety mechanism so you can quickly hit the cover down and deactivate the switch.

    Note: This is the cover for the switch only.

    Dimensions:
    • 1.5cm (W) X 5cm (L) X 2.75cm (H)
    • 0.59in (W) X 1.96in (L) X 1.08in (H)
    • note: taken with a tape measure, so allow for extra room

    FTDI Cable 5V
     
    Description: The FTDI cable is a USB to Serial (TTL level) converter which allows for a simple way to connect TTL interface devices to USB. The I/O pins of this FTDI cable are configured to operate at 5V.

    The FTDI cable is designed around an FT232RQ, which is housed in a USB A connector. The other side of the cable is terminated with a 0.1" pitch, 6-pin connector with the following pinout: RTS, RX, TX, 5V, CTS, GND (RTS is the green cable and GND is black).

    This cable has the same pinout and functionality as our FTDI Basic Breakout board; you can use it to program your Arduino Pro, Pro Mini and Lilypad. For use with those boards, align the black and green wires of the FTDI cable with the 'BLK' and 'GRN' labels on the PCB.

    There are pros and cons to the FTDI Cable vs the FTDI Basic. The FTDI Basic has great LED indicators, but requires a Mini-B cable. The FTDI Cable is well protected against the elements, but is large and cannot be embedded into a project as easily. The FTDI Basic uses DTR to cause a hardware reset where the FTDI cable uses the RTS signal. The cable is 1.8m or about 6ft long.

    Force Sensitive Resistor - Square  (Out of Stock)
     
    Description: This is a force sensitive resistor with a square, 1.75x1.5", sensing area. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR its resistance will be larger than 1MΩ. This FSR can sense applied force anywhere in the range of 100g-10kg.

    Two pins extend from the bottom of the sensor with 0.1" pitch making it bread board friendly. There is a peel-and-stick rubber backing on the other side of the sensing area to mount the FSR.

    These sensors are simple to set up and great for sensing pressure, but they aren't incredibly accurate. Use them to sense if it's being squeezed, but you may not want to use it as a scale.

    Dimensions:
    • Overall length: 3.5"

    QUAD TRIAC SWITCH CARD (Assembled)
     
    Relays are usually used to switch AC voltages by means of an electronic control because of their simplicity. However, when switching occurs too frequently or too quickly the life time of the contact points is shortened considerably. This can be solved perfectly by replacing the relays with a triac. Using optocouplers, the entire interface network remains electrically isolated from the voltage that has to be switched. (K2634)

    LIQUID LEVEL CONTROLLER (Assembled)
     
    Forgotten to turn off the tap, leaking washing machines, water level dropping in your aquarium, rain tank or water tank suddenly dry or over flowing, water in your cellar, etc. Such situations are often the cause of trouble and financial burden. Prevention is better than cure. So use this fluid detector. This multifunctional device is easy to use in a variety of applications : 1) LED control of set fluid level : LOW, MIDDLE, HIGH ; 2) Controller : the relay automatically switches a pump and/or valve to keep the fluid level between the LOW and HIGH marks ; 3) Alarm : if the sensor detects a level which is too high or too low (selectable), the relay will operate a bell or other alarm device.

    DUAL ELECTRONIC DICE (Assembled)
     
    Board games provide an excellent source of pleasant and healthy entertainment. However, the dice can be a constant source of distraction : they fall off the table, allow cheating, one or more players don't see the results properly and so on. There can be no doubt at all about the result displayed on this electronic dice module, and cheating is out of the question. Two fully independent dice. At your choice you can play with one or two dice. Displays are switched off automatically after 30 seconds to save battery power. (K3400)

    PARKING RADAR (Assembled)
     
    NEW - LOWER PRICE!
    Price was: $36.26

    If you have problems parking then this kit is for you. Using (ultrasonic) sound waves, whose frequency is beyond our range of hearing, we can "measure" a distance. Consequently, a sensor mounted at the back of the car can give an indication of the distance between your car and the car parked behind you or other obstacles (only at the same height as the sensor). When the preset minimum distance is crossed, an audible signal is generated. (K3502)

    STEREO TUBE AMPLIFIER / CHROME VERSION (Assembled)  (Out of Stock)
     
    Please note: This item is not carried ex-stock in our warehouse. This item will ship to you around 1 week after you submit your order.

    For most of us a high power tube amplifier is unaffordable. This kit changes that, so that now everybody can enjoy that sublime "tube sound". The sound of tubes has never been surpassed, nor by transistors, nor by FETs. In the course of developing this amplifier, special attention was given to the housing so that the expensive tubes are on display in a way that is very pleasing to the eye. The weakest point of an tube amplifier are the output transformers ; that's the reason why we use ultra-linear and over-rated output transformers (toroidal) to guarantee a rich bass response. To extend the life of the precious valves, the amplifier is provided with an switch on delay, so that the high voltage is switched on when the tubes are warmed up. (K4040)
