The safety unit provides 4 inputs. The EDM & START inputs can be defined freely.
The inputs may not be connected to other potentials, but rather only directly or
through potential-free switches to + (for EDM/START).
Switching current static 4 mA at 24 V, dynamic 30 mA at 24 V (T=100 µs).

Semiconductor outputs. Max. contact load: 0.5 A DC-13 at 30 V.
1.14, 2.14; 1.13, 2.13
Potential-free relay contacts. Safety relay with one contact set for read-back. Max.
contact load: 3 A AC-15 at 30 V, 3 A DC-13 at 30 V.
0 V, 24 V
Semiconductor outputs are powered by separate 24 V DC.
+ (for EDM/Start)
Output supply, powered by AS-i. May not be connected to other potentials, but
rather only directly or through potential-free switches to one of the EDM or START
inputs. Voltage 30 ... 15 V
Subject to reasonable modifications due to technical advances.
