1794-IE4XOE2 and 1794-IE4XOE2XT 4 Input/2 Output Analog
Combination Modules
The 1794-IE4XOE2 is a combination module with 4 inputs and 2 outputs.
Inputs can be configured individually for different modes. Inputs accept signals
from a variety of inputs sensors (2-, 3-, and 4-wire) in the range of ±10V or
0…20 mA. Outputs are also individually configurable for different modes.
Outputs produce signals in the range of ±10V or 0…20 mA.
1794-IE4XOE2XT is the extended temperature version of the 1794-IE4XOE2.
