INFORMATION
When the solenoid is operated in single-channel, only a safety level of PL d
(Cat. 2)/SIL CL 2 can be achieved.
To achieve PL e (Cat. 4/SIL CL 3, the solenoid must have dual-channel op-
eration, e. g. via safe pulsed semiconductor outputs with high current load
capacity (0.9 A for 50 ms).
