Siemens 6ES7144-4JF00-0AB0 SIMATIC ET 200pro EM 4 AI-RTD HF Analog Input Remote I/O Module

The Siemens 6ES7144-4JF00-0AB0 is a SIMATIC ET 200pro High Feature analog input module with 4 RTD channels covering Pt100/200/500/1000 and Ni100/120/200/500/1000 sensors, plus direct resistance ranges to 3000 ohms. It supports 2-, 3- and 4-wire connections, resolves 15 bit with overrange, and holds a temperature error of only 0.002%/K across four independently wired channels on the ET 200pro backplane.

Technical Specifications

Selection Notes

Support for both Pt and Ni resistance thermometers across nine sensor types, plus direct resistance ranges to 3000 ohms, means one module covers most RTD wiring already in a plant without matching a specific sensor type at order time. The 4-wire connection option removes lead-resistance error over long cable runs, which the simpler 2-wire mode doesn't correct for; use 4-wire whenever the RTD run exceeds a few meters. Choose the AI-TC module instead when the sensors are thermocouples rather than resistance elements.

Applications

Fits ET 200pro stations measuring process or bearing temperature from RTD sensors, such as tank, oven or motor-winding temperature monitoring where 0.002%/K temperature stability matters over long production runs.
