, PL e, SIL3
Output testing:
Always active (Test pulse: max. 600 μs, mini-
mum range between two test pulse: 4 ms)
Voltage at switched of output: Max. 2.4 V
Effect by incorrectly connection (external
voltage on output):
Potential defect

Category 4 hence PL e and therefore PL e are only valid, if the following
SDOs pairs are used: SDO0 + SDO1, SDO2 + SDO3, SDO4 + SDO5, ...

Quantity: 2 (SDO8 - SDO9)
Type:
Protected output (according to EN 611-31-2),
non storing
Nominal voltage: 24 V DC PELV
Norminal current: 2 A
Inductive load (Energy): 200 mJ at 0.2 Hz
Capacitive load: Max. 200 nF
Status display: Orange LED
