2.11 Power supply

The safe PROFINET gateway is operated using a 24 V DC voltage which is supplied

redundantly.

2.11.1 Power supply principle

The figure below shows the principle for the redundant power supply of the safe PROFINET

gateway. Supply the FL PN/PN SDIO-2TX/2TX with 24 V DC each at voltage inputs

U

are electrically isolated inside the device.

The electronics inside the device monitor both input voltages. They make sure that the safe

PROFINET gateway is supplied with voltage with an output value that is within the valid

range.

For more detailed information on the insulation voltage/electrical isolation and on the input

voltage range, please refer to “Technical data” on page 61.
