Current loop converters convert an analog or digital signal to a current loop output such as 4-20 mA or 0-20 mA

Electrical current sensors measure AC and/or DC current levels.

Voltage-to-frequency converter chips provide a signal frequency output as a function of an analog input voltage

Voltage-to-frequency converters accept a voltage signal and convert its analog level to a signal with a corresponding frequency

Loop powered devices are modules and computer boards which are powered by the system they serve.

Current sense amplifiers are integrated circuits with operational amplifiers and sense resistors that are used in measuring the amplitude and direction of current in circuits

Serial data converters are used to interconnect two different serial standards, such as RS232 to RS422, USB to RS232, etc.
