INFORMATION

In the case of single-pole wiring of the safe digital inputs/outputs, the feasible safety integrity level pursuant to EN 62061/EN 61800-5-2 is reduced to SIL 2 or the performance level pursuant to EN ISO 13849-1 is reduced to PL d. Continue to observe the installation requirements.
When using the F-DO0x outputs in the single-channel, sourcing output connection variant, the PFH value increases to 5.3 × 10−9 1/h.
