In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...
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 ...
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 ...
Murrelektronik optocouplers, slim interface relays and multi-mode relay timers are now available from AutomationDirect. Murrelektronik optocouplers (from $16.50) are used to combine different signal ...
Off-the-shelf Solid State Relays (SSR) are reliable and compact, but it’s hard to find one that can conduct more than a few hundred milliamps of current. If you need an isolated SSR to switch line ...
