Company Announcement - When a 4-20mA loop transmitter is calibrated or configured it requires a 24 volt power supply – often in remote field locations without easy access to AC power. Additionally, ...

For VCRs, TVs, and other equipment that requires a standby mode, you must supply power to a µP when other components are asleep to receive and interpret any wake-up signal from the remote control or ...

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 ...

The loop output can go directly to an ADC (analog-to-digital converter) or DMM in the configuration of K22 shown. If, however, filtering is needed to reduce noise during measurements, K22 can be ...
