 Outputs
Output function  2 safety-related switching outputs (floating contacts)
1 fault output "Fault" (positive switching)
1 diagnostic output "Overspeed" (positive switching)
Output data  Fault output "Fault" Y7 and diagnostic output "Overspeed" Y8
≤ 20 mA, 24 V DC, voltage drop ≤ 2 V DC, short-circuit proof, non safe
Contact rating  6 A, 250 V AC / 24 V DC (≥ 6 mA); ohmic resistance
Short-circuit protection  The contacts are to be protected by means of fuses with a nominal current of < 3.6 A.
