Description of 1734-IE2C
The 1734-IE2C module is a member of the Allen-Bradley 1734 series
of distributed I/O modules. This module operates at an input
current of 4 to 20 mA or one of 0 to 20 mA. For wiring input
signals, recommended wire size is 22 to 14 AWG solid or stranded
shielded copper wire rated at 167 degrees Fahrenheit or higher.
This module weighs approximately 0.036 kilograms or 0.08 pounds. In
addition, it has an open-style enclosure type rating and it has
dimensions of 56 x 12 x 75.5 millimeters or 2.21 x 0.47 x 2.97
inches. The 1734-IE2C’s compact design makes installation easy and
it can be mounted horizontally or vertically.
The 1734-IE2C POINT I/O current input analog module has 2
single-ended, non-isolated channels. It gives 16 bits across a 0 to
21 mA resolution. When mounting to a terminal base, position the
key switch at 3. The 1734-IE2C is a 2-channel module that converts
an analog input current to a digital value and reads a current
input between 0 to 20 mA or 4 to 20 mA depending on the mode that
is selected. The supported networks include ControlNet, DeviceNet,
and EtherNet/IP. Moreover, the 1734-IE2C uses an external DC power
supply rated at 10 to 28.8 Volts DC and 24 Volts DC nominal, and it
uses a current with a 10 mA rating. The 1734-IE2C is rated to
withstand 2550 Volts DC for 60 seconds and it has 50 Volts of
continuous isolation voltage. It gives off a maximum power
dissipation of 0.6 W at 28.8 Volts DC and a maximum thermal
dissipation of 2.0 BTU/hour at 28.8 Volts DC.
The 1734-IE2C is basically an analog input card that requires a
terminal base to function. Compatible terminal bases for use with
this analog input module include 1734-TB, 1734-TBS, 1734-TOP, or
1734-TOPS. This module support vertical and horizontal mounting and
support mounting to a standard 35 mm DIN rail. When mounting the
module to the appropriate terminal base, the module’s keyswitch
must be positioned at position 3.
The 1732-IE2C has an internal Analog to Digital (ADC) converter
which has a conversion resolution of 16 bits – over 0...21 mA 0.32
μA/cnt using Delta-Sigma conversion. Converted data is stored in
Signed Integer format with absolute accuracy of 0.1% Full Scale @
25 °C (77 °F) with accuracy drift of 30 ppm/°C.
The 1734-IE2C is compatible for use with any Allen-Bradley
controller platform. Most especially, it is well suited with the
Logix product family specifically, CompactLogix and ControlLogix
controller platforms. This module supports a variety of
communication adapters which enable the module to communicate to
the master controller over a particular industrial protocol.

The 1734-IE2C is an analog input module that is part of
Allen-Bradley’s POINT IO product family. This module features Two
(2) single-ended, non-isolated Current input channels. Each channel
is configurable for 0-20 mA and 4-20 mA output signals with 16 bits
resolution - over 0...21 mA 0.32 μA/cnt. It is compatible with any
POINT IO communication adapter, typically used for implementing
distributed I/O architecture. This module requires 1734-TB,
1734-TBS, 1734-TOP, or 1734-TOPS wiring base assemblies.
