Parallel port output module (V2) (Assembled)

This is our Kit 74V2 but put into a box with top quality Dinkle connectors to the relays. With the rapid progress in computer technology many people now have a surplus computer just gathering dust somewhere. Thus these computers are free to be used as dedicated controllers for a variety of uses: turning on/off lights or other devices around the home, office, laboratory or factory come to mind. All that is needed is the interface to connect it to the real world. (CPA165)

PC Printer Port Relay Board (Assembled) (version 2)

Do you have an old PC lying around the house which absolutely no one wants? Then you can convert it into a dedicated controller. Communicate with the real world via the parallel printer port on your PC. Simply connect a DB25 straight trough cable from computer to DB25 connector on the relay board. There are 8 relays each capable of switching 12VDC/10A or 240VAC/5A. Each relay has an LED to indicate when it is operated. We provide two sets of complete, stand-alone software to control the relays: one works under DOS so you can write your own batch files to control individual relays, the other works under Windows. Needs 12VDC center positive 2.5mm power supply. PCB Size 6.75" x 2.75" (CPA74)

DS1820 TO92 IC

The DS18S20 Digital Thermometer provides 9–bit temperature readings which indicate the temperature of the device. Information is sent to/from the DS18S20 over a 1–Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor to a DS18S20. Power for reading, writing, and performing temperature conversions can be derived from the data line itself with no need for an external power source. Because each DS18S20 contains a unique silicon serial number, multiple DS18S20s can exist on the same 1–Wire bus. This allows for placing temperature sensors in many different places. Applications
where this feature is useful include HVAC environmental controls, sensing temperatures inside buildings, equipment or machinery, and process monitoring and control.

DS1213C Smart Socket (SC7)

"The DS1213C SmartSocket is a 28-pin, 600 mil DIP socket with a built-in CMOS controller circuit and an embedded lithium energy source. It accepts a 32K x 8 JEDEC bytewide CMOS static RAM. When the socket is mated with a CMOS RAM, it provides a complete solution o problems associated with memory
volatility. The SmartSocket monitors incoming VCC for an out-of- tolerance condition. When such a condition occurs, the internal lithium energy source is automatically switched on and write protection is unconditionally enabled to prevent data corruption."
