Note
Inrush current
The requirements in accordance with NAMUR NE21, Section 4.5 are complied with. The
maximum inrush current does not exceed 4 A. Typical value with an input voltage of 24 V is 2
A for 25 ms. A 24 V power source with a limit current lower than 2.0 A is not permitted. A
voltage drop under 18.0 V during booting of the device is not permitted.
