Series connection
The safety sensors PSENcode are also suitable for series connection with other sensors.
Maximum number of PSENcode sensors switched in series connections for SIL CL 3 using
SDD
}
PSENcode large design (PSEN cs1.xp - cs2.xp): 8
When using other SDD-compatible sensors, the number must be recalculated.
In practice, the maximum possible number will be limited by the following parameters,
among others:
}
The required SIL level (e.g. SIL CL 3),
}
the required performance level (e.g. PL e (Cat. 4)),
}
the maximum delay or risk time permitted by the application.
Ensure there is sufficient supply voltage, taking inrush currents and fusing into considera-
tion.
