1.4 Power supply
Only for device variants featuring supply voltage with characteristic value C
(24 V DC ... 48 V DC), K (60 V DC ... 250 V DC / 110 V AC ... 230 V AC,
50 Hz ... 60 Hz) or W (24 V DC):
For redundant and failure-resistant power supply, you have the option of
connecting multiple voltage sources in any combination at the same time.
The device selects the used voltage source automatically.
Switching to a redundant voltage source possibly occurs with a short delay.
If the active power source is lost and another power source takes over the
power supply to the device, the device reboots if necessary to activate the
redundant power supply.
1.4.1 Supply voltage with the characteristic value C
(24 V DC ... 48 V DC)
A 4-pin 7/8" plug is available for the power supply to the device.
Further information:
“Supply voltage with the characteristic value C (24 V DC ... 48 V DC)” on
page 47
1.4.2 Supply voltage with the characteristic value K
(60 V DC ... 250 V DC / 110 V AC ... 230 V AC, 50 Hz ...
60 Hz)
A 3-pin 7/8" plug is available for the power supply to the device.

“Supply voltage with the characteristic value K (60 V DC ... 250 V DC /
110 V AC ... 230 V AC, 50 Hz ... 60 Hz)” on page 47
1.4.3 Supply voltage with the characteristic value P
(Power supply only through PoE)
Note: With supply voltage with the characteristic value P (Power supply only
through PoE), the signal contact is omitted.
Your device is a PD (powered device). PSE (power sourcing equipment)
connected via a twisted pair cable on the PoE PD port serves as the PoE
power supply voltage. The PoE power supply means that no separate power
supply is required for your device.
