4.4.4 Power Supply
Voltage 1L, 2L
24 VDC, –25 %/+30 % (18 VDC ...31.2 VDC)
Voltages above 34 V can permanently damage the
product.
Voltages below approx. 10 V lead to a product reset.
Undervoltage warning
17.0 V (17.5 V −3 %) ON message,
18 V (17.5 V +3 %) OFF message
Overvoltage warning
32.1 V (31.2 V +3 %) ON message,
30.3 V (31.2 V −3 %) OFF message
Module power consumption
1L: 0.2 A (at 24 VDC)
2L: 0.1 A (at 24 VDC)
Power consumption of supply connections
Max. 16 A; ensure external limitation or use fuses in
the cables
The maximum total current of the device, including
transmission between the power supply connections,
must not exceed 16 A for both 1L and 2L individually. If
additional modules are connected to X32 (PWR OUT),
it may be necessary for the maximum total current to
be monitored with external power supply management.
Maximum current: Observe derating as a function of
temperature
Conductor cross-section
For UL-compliant use: 2.5 mm
2
Reverse voltage protection
Yes
4.4.5 Electrical Safety
Insulation resistance
60 VDC
Test voltage
550 VAC RMS
Min. creepage distance
0.7 mm
Requirements
• Use of PELV/SELV power supplies with fault voltage limited to 60 VDC.
• When SELV power supplies are used: SELV power supplies with supply via the same
network phase
• If PELV (Protective Extra Low Voltage) power supplies are used: PELV (Protective Ex-
tra Low Voltage) power supplies with a secondary power supply connection to the
common reference point
4.4.6 Environmental Conditions
Surrounding air temperature (operation)
