Specifications - 1734-APB PROFIBUS Adapter Module
Communication Interface Specifications
Expansion I/O Capacity Up to 13 modules (13 times 75mA = 0.975, just under the limit
of 1.0A). The actual number of modules can vary. Add up the
current requirements of the modules you want to use to make
sure they do not exceed the amperage limit of the 1734-ADN.
(Note: Total expansion up to 63 modules - 13 modules maximum
with 1734-APB - add 1734-EP24DC modules for an additional 17
modules (or less based on current requirements), up to 63
module maximum)

Power Supply Specifications
Power Supply 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.
