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

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 ...

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 ...

The XTA-MRNO-6 is an interposing relay module with six digital inputs and six mechanical relay outputs intended for use with digital output modules for driving high energy loads. This module serves as ...

1. The well-established relay-driving circuit uses an optocoupler to isolate the grounds and noise coupling between the low-voltage digital-control signal circuit (left) and the relay as load (right).

“These multi-channel discrete contact sensor and relay output modules offer a safe, isolated interface between high-energy field devices and sensitive control system I/O modules,” explained Don Lupo, ...
