For safety-oriented applications, the Safety Local Isolator Module with safe input and easy-to-adjust basic functions as well as a 400V Disconnecting Module are available. The two devices (only) work effectively together, since the 400V disconnect module facilitates double disconnection of the main circuit supply and feedback of the module's functional state via the bus.
These two components permit safe shutdown of the 400 V supply of the motor starters up to Category 4 / SIL 3.
Safety Local Isolator Module
The safety local isolator module features the same functions as a standard isolator module with an additional local safety function.
In the case of EMERGENCY STOP, the safety local isolator module switches the series-connected 400 V disconnecting module. This safely isolates the 400 V circuit up to CAT 4.
Disconnecting Module 400V
The 400 V disconnecting module can be used together with the safety local isolator module for local safety applications.
It contains two contactors connected in series for safety-oriented tripping of the main circuit. The auxiliary circuit supply of the device is via a safety power rail in the backplane bus module.
The ET 200pro safety motor starters Solution PROFIsafe is perfectly suited when safety technology on the control level is called for. Standard and safe communication are transmitted via a single bus system – PROFIBUS or PROFINET with PROFIsafe profile.
The modularity of the ET 200pro offers the possibility of realizing an easy conversion to PROFIsafe solutions using the F-Switch module. In connection with the 400 V disconnection module, a failsafe shutdown of the ET 200pro motor starters up to Cat. 4/SIL 3 is possible with PROFIsafe applications.
In addition, the high degree of protection IP65/67 does away with the on-site control cabinet.
The F-Switch is a failsafe electronic module for PROFIsafe safety applications. It is equipped with failsafe inputs and outputs for the reliable switching of the 24 V supply via backplane bus rails.
400 V Disconnecting Module
The 400 V disconnecting module can be employed for safety applications in connection with the F-Switch for PROFisafe.
It contains two contactors switched in series for a failsafe disconnection of the main circuit. The auxiliary supply of the device is realized via a safety bar in the backplane bus module.
