A-2 Specifications
DeviceNet Power Specifications
Power Supply Note: In order to comply with CE Low Voltage
Directives (LVD), you must use a Safety Extra Low
Voltage (SELV) or a Protected Extra Low Voltage
(PELV) power supply to power this adapter.
Input Voltage Rating 24V dc nominal
DeviceNet Input Voltage Range 11-25V dc DeviceNet specification
Input Overvoltage Protection Reverse polarity protected
DeviceNet Power Requirements 24V dc (+4% = 25V dc max) @ 30mA maximum
Power Supply Specifications
Power Supply 1 Note: In order to comply with CE Low Voltage
Directives (LVD), you must use either a NEC Class 2,
a Safety Extra Low Voltage (SELV) or a Protected
Extra Low Voltage (PELV) power supply to power this
adapter. A SELV supply cannot exceed 30V rms,
42.4V peak or 60V dc under normal conditions and
under single fault conditions. A PELV supply has the
same rating and is connected to protected earth.
Input Voltage Rating 24V dc nominal
10-28.8V dc range
Field Side Power Requirements 24V dc (+20% = 28.8V dc maximum) @ 400mA
maximum
Inrush Current 6A maximum for 10ms
PointBus Output Current 1A maximum @ 5V dc ±5% (4.75 - 5.25)
Input Overvoltage Protection Reverse polarity protected
Interruption Output voltage will stay within specifications when
input drops out for 10ms at 10V with maximum load.

1. For the 1734-ADN, DeviceNet and user supplied power (I/O power) should be powered from separate
sources. For the 1734-ADNX, because there are three inputs, for CE purposes, the user supplied power must
be separate from the other two (because of surge testing). DeviceNet and the Subnet can be powered from
the same source.
