Specifications
General
Attribute Value
Number of modules supported,
maximum 63
Number of rack optimized
connections 5 (for digital modules only)
Number of direct connections,
maximum 20
Backplane output current,
maximum 0.8 A
The actual number of modules can vary. Add up the
requirements of the modules you want to use, for
current, to make sure they do not exceed the
amperage limit of 0.8 A for the 1738-AENTR.
Backplane current can be extended beyond 0.8 A by
using a 1738-EP24DC Backplane Extension Power
Supply. Add multiple 1738-EP24DC modules to
achieve the maximum limit of 63 modules.
Input voltage rating 24V DC nominal
10…28.8V DC range
Field side power requirements 24V DC (+20% = 28.8 V DC maximum) @ 400 mA
maximum
Inrush current, maximum 6 A for 10 ms
Interruption Output voltage will stay within specifications when
input drops out for 10 ms at 10V with maximum load.
Input overvoltage protection Reverse polarity protected
