The electrically isolated contacts can be used for many applications such as signalling, turning on lights, strobes etc. It has volt-free contacts (Normally Open and Normally Closed) as standard but can be wired to give a 230V output or 24V output using an external 24V supply. The Ei428 is mains powered and has a backup rechargeable lithium cells in the event of mains power failure.
