There is a common misconception that optocouplers will always fail with an “open” circuit when a high-voltage event breaks the device. Although there are many ways that an optocoupler can fail open, ...

Designed specifically for high-voltage sensing, a new generation of optically isolated amplifiers make monitoring and system protection circuits more accurate and easier to design. These iso-amps can ...

Isolation is a means of preventing direct current (DC) and unwanted alternating current (AC) between two parts of a system, while still allowing a signal and power transfer between those two parts.

Vishay has introduced a precision isolation amplifier with 5kVrms isolation test voltage and 150kV/μs typical (100kV/μs min) common-mode transient immunity: VIA0050DD. “Isolation amplifiers in the VIA ...

AutomationDirect's ProSense universal input conditioners/isolators accept a wide range of RTD, thermocouple, resistance, potentiometer, mA or voltage inputs, and offer current, voltage and/or relay ...

Having problems with your process controls and electrical instrumentation? The source may be a grounding disturbance known as a ground loop. According to the ANSI/ IEEE Standard Dictionary of ...

Many new designs today absolutely require galvanic isolation between two or more pieces of equipment, or between two critical sections of a single product or system. If you haven’t done this before, ...

TCC-82 signal isolators provide bidirectional serial communication with full electrical isolation between two RS-232 devices. These isolators protect both sides of the connection optically from ...
