These Leybold start/stop switches can be used to remotely turn the turbo pump on and off. When the Turbo.Controller 300 is in remote mode (remote switch is located on the back of the controller) the start/start switch is needed to start the turbo. The switch can be mounted at a distance, for example, in your control panel, by using a straight through RS-232 extension cable. The TURBO.DRIVE 400 requires a supply voltage of 24 V DC. It is equipped with interfaces for programmable controls (Remote Switch PID: P105455).
