A latching relay is a relay which only draws power during the brief voltage pulse required to make it change state. These are very useful in situations where energy efficiency is important, but also in sitations where you need the relay to remember its state – typically so that the user can press a button to close the relay , and press a second button to open the relay again. The devices PNOZ s PNOZ sand PNOZ s4. E-STOP and safety gates, their area of application also includes monitoring of light guards. The second advantage of using a relay is that it can be wired so that the circuit only goes live when the ignition is switched on.
