The REMLIVE RL-24i Isolator Check provides the user with a positive check when isolating plant. It provides electrical isolation between the DIN rail unit and the door mounted display unit. The door unit is designed to fit through the front of a control panel or switch so the user can see a live/isolation status. The super bright REMLIVE RL-24i display provides the user with a quick and easy method of proof of isolation in lock out / tag out procedures.
