In electronic and industrial automation systems, relay modules play a crucial role by allowing low-power control signals to switch high-power devices. Selecting between a 5V relay module and a 12V ...

Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...

Few realize how close an optical coupler resembles a relay. It is so close, in fact, that one can be wired as a Run-Stop latch circuit. One advantage over the relay is that it may be turned off via a ...

WIXOM -- The Wixom manufacturing electronics manufacturer Acromag has released new BusWorks XT Series multi-channel optocouplers and interposing relay modules that connect discrete field devices to ...

Many microcontroller designs typically mix multiple interfacing methods. A microcontroller (µC) system can be viewed as a system that reads from inputs, performs processing and writes to outputs.

Optocouplers provide high-voltage isolation between a low-voltage device like a microcontroller or a pulse-width modulation (PWM) generator and a high-voltage device like an intelligent or integrated ...
