The HCPL-4100 isolated 20 mA currrent loop transmitter is designed to operate as a transmitter in equipment using the 20 mA current loop. 20 mA current loop systems conventionally signal a logic high ...

Significant efficiency and performance improvements can be realized by improving the current loop’s power supplies, replacing linear regulators with high-efficiency buck regulators. It also increases ...

To complement the 2-wire and 3-wire sensor transmitter blogs that Kevin Duke and I have already published on Precision Hub, my next few blog topics will be on 4-wire sensor transmitters. The blogs ...

Many industrial and control applications use analog current loops as the physical link for measurements and actuator control. Although several ranges are used, the most popular is still the 4- to ...

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 ...

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 ...

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, ...

Many instrumentation and control applications use analogue current loops as the physical links for telemetry measurements and remote actuator control. Most popular is the 4 to 20mA standard, in which ...
