Siemens 6ES7144-4FF01-0AB0 SIMATIC ET 200pro EM 4AI-U HF Analog Input Remote I/O Module

The Siemens 6ES7144-4FF01-0AB0 is a SIMATIC ET 200pro High Feature analog input module with 4 voltage channels covering 0 to 10 V, 1 to 5 V, -5 to +5 V and -10 to +10 V. It resolves 15 bit plus sign with a linearity error of only 0.0075%, and it mounts on the ET 200pro bus module with a separate connection module ordered apart.

Technical Specifications

Selection Notes

The four selectable voltage ranges, including bipolar +/-5 V and +/-10 V, mean this module covers most standard sensor and transducer voltage outputs without a separate range-specific part. Its 15-bit-plus-sign resolution and 0.0075% linearity error are High Feature grade, worth choosing over a standard-accuracy analog input module wherever a control loop is sensitive to measurement noise, and the parameterizable smoothing (1x/4x/16x/64x cycle time) trades response speed for further noise reduction when the process is slow.

Applications

Fits ET 200pro stations reading analog voltage signals from process transmitters, potentiometers or 0-10 V sensors where measurement accuracy matters, such as level, position or setpoint feedback loops.
