“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, ...
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 ...
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 ...
What is a relay? What is zero voltage switching? How to create a zero-crossing relay driver with a simple external circuit. A relay is a device that allows for a smaller electronic switch to control a ...
Introducing a series of 90 V/1.0 Ω hermetically sealed power MOSFET optocoupler, Avago’s HSSR-7111#100 series. The HSSR-7110, HSSR-7111, HSSR-7112, HSSR-711E and SMD 5962-93140 are single channel ...
