Are there any 4-20mA current loop products?
The MAX15500/MAX15501 analog output conditioners provide a programmable current up to ±24mA, or The MAX15500/MAX15501 analog output conditioners provide a programmable current up to ±24mA, or The MAX12900 is an ultra-low-power, highly integrated 4-20mA sensor transmitter. The MAX12900 in…
What is the span of a 4 to 20 mA signal?
The range of a signal consists of two values, such as 4 mA to 20 mA, or 1 VDC to 5 VDC. The span of a signal is the difference between the two ends of the range, such as 16 mA and 4 VDC, respectively. www.PDHcenter.com PDH Course E271 www.PDHonline.org © David A.

Is the max12900 a 4-20mA sensor transmitter?
The MAX12900 is an ultra-low-power, highly integrated 4-20mA sensor transmitter. The MAX12900 in… The MAX12900 evaluation kit (EV kit) provides a proven design to evaluate the MAX12900, loop-pow…
Which is the low end of the analog signal range?
An analog signal range that has a non-zero low-end, such as 3 to 15 PSIG or 4 to 20 mA, is known as a “live-zero”range because the low end is not dead, but has some pressure, voltage, or current present at all times. Before the 1970s, most analog loops were 3 to 15 PSIG pneumatic loops.
What do you need to know about Maxim current loop?
Maxim provides a wide range of products designed for implementing and protecting 4-20mA communication links. Faulty current loop conditions as well as reverse inputs can easily damage sensor devices. Maxim… Analog signals from sensors need to be conditioned or prepared for further processing, e.g., for…
Why are current loops used in analog communication?
Current loops are useful for accurately communicating analog signals over long distances. Unlike voltage, current does not vary due to line resistance or capacitance—both which change with cable length. Current loops provide a high level of noise immunity. As a result, they are widely used in electrically noisy environments.
