1794-IF2XOF2I and 1794-IF2XOF2IXT 2 Input/2 Output Isolated
Analog Combination Module
The 1794-IF2XOF2I is a combination module with 2 inputs and 2 outputs with
isolated, individually-configurable channels. Inputs accept signals from a variety
of input sensors (2-, 3-, and 4-wire) in the range of ±10V or ±20 mA. Outputs
produce signals in the range of ±10V or 0…20 mA.
The 1794-IF2XOF2IXT is the extended temperature version of the
1794-IF2XOF2I module.
Dimensions (HxWxD), approx 46 x 94 x 53 mm (1.8 x 3.7 x 2.1 in.)
94 x 94 x 69 mm (3.7 x 3.7 x 2.7 in.) installed
Temperature, operating 1794-IE4XOE2: 0…55 °C (32…131 °F)
1794-IE4XOE2XT: -20…70 °C (-4…185 °F)
(1) Includes offset, gain, non-linearity and repeatability error terms.
ATTENTION: Only connect either a voltage input or a current input per
channel, not both.
