Maximum achievable safety class in safety
mode
SIL according to IEC 61508, DIN EN 62061
Performance Level according to EN ISO 13849-1
Category according to EN ISO 13849-1
Failsafe performance characteristics
Resistive and protected inductive loads
(unprotected inductive loads should not be used
for failsafe functions)
Low Demand (PFD) according to SIL 2
(per channel)
High Demand (PFH) according to SIL 2
(per channel)
SIL 2
DC: PLb | AC: PLc
DC: Cat. B | AC: Cat. 1
< 2,53 E-2 (up to 10 yr proof time)
< 5,06 E-2 (up to 20 yr proof time)
< 5,77 E-7 1/h
Note:
SIL2 requires that there is a signal change at least once a year and that the
process status is read back.
If a fault is detected during this function test, replace the Relay MTA module.
