The I/O capabilities built into most microcontrollers make it easy to measure the analog world. Say you want to build a data logger for temperature. All you need to do is get some kind of sensor that ...

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 ...

Sealevel Systems, Inc. adds a new 4-20 mA current loop board to the SeaRAQ family of I/O expansion designed for Relio industrial computers. Sealevel Systems, Inc. adds a new 4-20 mA current loop board ...

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 ...

Current-mode control loops (particularly the popular 4- to 20-mA controls) are used in many industrial applications because of their immunity to induced EMI from motors, contactors, relays, and other ...

The MR267 current-loop controller (CLC) optional attachment remotely controls a motorized potentiometer or rotary camswitch via 4 to 20-mA current loop, 0 to 2.5-V input, or external potentiometer.

Each channel operates independently to prevent interaction between channels. Galvanic isolation eliminates ground loops, reduces noise, and blocks transient signals. Splitters are available in 2-wire ...

This application note’s primary goal is to provide an easy-to-understand primer for users who are not familiar with 4-20mA current-loops and their applications. Some of the many topics discussed ...
