This design will interest technicians who work on pneumatically operated valves and other 4-20mA current loop controlled devices. Although 4-20mA signal injector/calibrators are available, this one is ...

This reference design shows how to develop a high-performance, high-voltage 2- or 3-wire 4–20mA current-loop transmitter suitable for industrial process control and ...

Imagine this scenario: There is a flow meter with 4–20 mA output setup. The switch is flipped, thereby turning it on. Then it is noted that the readings are off, and the required output is not shown.

With an eye on factory automation, Maxim has released a reference design for a precision 4-20mA temperature transmitter with added data capability. The whole thing, branded Novato, is loop-powered, ...

Galvanically (that is, optically or electromagnetically) isolated 4- to 20-mA current loops offer robust noise immunity and tolerate long cable runs. These advantages, combined with simple unshielded ...

Analog Devices has designed a high-resolution data acquisition chip for 4-20mA current loops around an ARM Cortex-M3 core. Called ADuCM360, the chip includes dual 4ksample/s 24-bit sigma-delta DACs ...

Over long cable runs, an isolated 4-to-20-mA current loop offers robust noise immunity and tolerance. This characteristic makes it popular for analog data ...

A whitepaper that explains the proper way to use and install transmiters in a current loop is now available from Acromag. As the leading analog transmission standard for industrial I/O, the future ...

To reduce noise and voltage drops in analog voltage signals, the market place has adopted an analog current (4-20mA) output as its sensor signaling standard. A very robust signal, 4-20mA current ...

Acromag 600T series signal splitters receive a 4-20mA current input and provide two identical isolated 4-20mA output signals. Acromag 600T series signal splitters receive a 4-20mA current input and ...
