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.
CAUTION!
Extension of delay-on de-energisation
When several (n) devices are connected in series, the delay-on de-ener-
gisation time adds with the number of interconnected safety switches.
The max. delay-on de-energisation is made up of the
risk time (see Technical details [ 23])
+ (n-1) x max. delay-on de-energisation of the inputs
+ max. delay-on de-energisation of the evaluation device
} When making series connections using SDD, only use the following passive junctions.
– PSEN ix2 F4 code
– PSEN ix2 F8 code
– PSEN Y junction M8-M12/M12 PIGTAIL
– PSEN Y junction M12-M12/M12 PIGTAIL
– PSEN Y junction M12 SENSOR
– PSEN Y junction M12 cable channel
