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 ...
The Loop-Powered Transmitter (LPT) joins the more than 20 loop-powered devices—from digital panel meters to controllers—made by Otek Corp. The LPT uses a patent-pending technique, along with ...
Tracking down cable cuts and differentiating them from normal open circuits is critical. Flexibly evolving the circuit design ...
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 ...
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 ...
Use of 4-to-20-mA current loops involves more than just a simple series connection between sensor, display, and power supply. The point where a sensor takes a measurement is, at times, many yards away ...
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 ...
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, ...
Essex-based Pickering Interfaces has announced a PXI-based module that simulates current loop based sensors in industrial control applications – a PXIe version is also available. Called ’41-765 Analog ...
