The 4–20 mA convention was born in the 1950s out of the earlier highly successful 3–15 psi pneumatic control signal standard, when electronics became cheap and reliable enough to emulate the older standard electrically. The 3–15 psi standard had the same features of being able to power some remote devices, and have a "live" zero.
A digital current loop uses the absence of current for high (space or break), and the presence of current in the loop for low (mark). [1] This is done to ensure that on normal conditions there is always current flowing and in the event of a line being cut the flow stops indefinitely, immediately raising the alarm of the event usually as the heavy noise of the teleprinter not being synchronized ...
For example, equipment sold in Europe, South Africa and Hong Kong used UHF channels 30–39 for this purpose. Equipment sold in Japan used channel 1 or 2 (Channel 13–16 is for cable converters). With other channels being used for RF modulation function in other regions, channel 3/4 output is a misnomer for those regions.
Drake TR-4, W-4, MS-4 circa 1971. The R. L. Drake Company is a manufacturer of electronic communications equipment located in Springboro, Ohio.It is also known for its line of equipment for amateur radio and shortwave listening, built in the 1950s through the 1980s.
In electronics, a transimpedance amplifier (TIA) is a current to voltage converter, almost exclusively implemented with one or more operational amplifiers. The TIA can be used to amplify [ 1 ] the current output of Geiger–Müller tubes , photo multiplier tubes, accelerometers , photo detectors and other types of sensors to a usable voltage.
A frequency changer or frequency converter is an electronic or electromechanical device that converts alternating current of one frequency to alternating current of another frequency. The device may also change the voltage , but if it does, that is incidental to its principal purpose, since voltage conversion of alternating current is much ...
The Ohio House voted Wednesday to make it harder to sell catalytic converters stolen off of vehicles. Rep. Bill Roemer, R-Richfield, one of sponsors of House Bill 328, said it will bolster law ...
An analog signal to discrete time interval converter (ASDTIC) is a specialized kind of an analog-to-digital converter, which converts the analog input signal (e.g. voltage or current) to time intervals between pulses. This conversion is a type of Pulse-width modulation (PWM). The origin of the term ASDTIC lies with NASA around 1970. [1]
