Relay Modules and Optocoupler Modules | WAGO
The relay modules plug directly onto the carrier terminal blocks of the WAGO TOPJOB ® S and Classic Rail-Mount Terminal Block Systems for easy, secure installation.
Using Opto Couplers
The start of the design process is to specify the input and output conditions the optocoupler is to link. Typical optocouplers can handle input and output currents from a few microamps to tens of milliamps.
How to Connect a Relay through an Opto-Coupler
The idea of operating a relay with an optocoupler is simple, it''s all about providing an input DC from the source which needs to be isolated to the LED pin outs via a limiting resistor (as we normally do with
