Series connection
The safety sensors PSENcode are also suitable for series connection with other sensors.
The series connection of maximum 32 sensors PSENcs 5.x and PSENcs 6.x is approved
for SIL CL 3 without using the SDD.
When using the SDD, the series connection of maximum 16 sensors PSENcs 5.x and
PSENcs 6.x is approved
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.
