        More Information

        Overview Manuals RTD Wiring Value Conversion Channel Diagnostics Field Mounting

        Features:

        • Two Pt100 inputs extend an ET 200X station with distributed resistance-temperature measurement.
        • Each channel supports two-, three- or four-wire sensor circuits through the documented M12 connections.
        • Wire-break, overrange, underrange and limit diagnostics identify measurement-path faults by channel.
        The EM 144 converts resistance changes into controller values while keeping the sensor wiring in the field-mounted I/O node.

        Selectable integration aligns conversion with 50 or 60 Hz interference suppression on the shielded measurement cable.

        Connector sealing and channel parameterization need to be preserved together when the module is exchanged.

        The Siemens 6ES7144-1JB31-0XB0 ET 200X EM 144 AI 2 RTD Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Pt100 lead arrangements

        • Two-wire circuit: Both lead resistances remain in the measurement path and must be considered in the configured result.
        • Three-wire circuit: The matched third lead supports compensation according to the documented terminal assignment.
        • Four-wire circuit: Separate source and sense leads remove the connecting lead resistance from the measured element path.
        • Connector boundary: The field sensor circuits enter through the specified 4/5-pin M12 connectors.

        Turning Pt100 resistance into controller data

        • Excitation: The module applies a typical 1.5 mA measuring current to the resistance-type transmitter.
        • Linearization: Parameterizable Pt100 linearization converts resistance to the assigned temperature value.
        • Digital format: Values are available in S7 or S5 format with 12 bits plus sign.
        • Noise rejection: Integration of 16.7 or 20 ms corresponds to 60 or 50 Hz interference suppression.

        What the channel diagnostics report

        • Lead failure: Wire-break detection identifies an open Pt100 measurement circuit.
        • Range state: Overflow and underflow messages show when the converted value exceeds its range.
        • Limit events: Upper and lower limit alarms are assigned separately by channel.
        • Module indication: The red group-error LED summarizes a diagnostic condition at the module.

        Installation details tied to the field enclosure

        • Ingress protection: IP66/IP67 depends on intact housing, seals and correctly tightened field connectors.
        • Cable run: The shielded RTD cable length is limited to 30 m.
        • Module width: The expansion-module body occupies the documented 60 mm module width within the ET 200X assembly.
        • Sensor boundary: Keep the shield and connector routing separate from interference sources that can disturb resistance measurement.
        Description
        Siemens 6ES7144-1JB31-0XB0 is the SIMATIC ET 200X EM 144 AI 2 RTD expansion module. It adds two Pt100 resistance-temperature inputs to a distributed ET 200X station and returns the converted temperature values to the controller through the module's analog data path.

        Each channel on 6ES7144-1JB31-0XB0 can be wired as a two-, three- or four-wire resistance circuit. A four-wire connection separates both lead pairs from the measuring element, while three-wire compensation and two-wire operation use the corresponding documented terminal arrangement and therefore cannot be interchanged without updating the wiring and channel setup.

        The integrating converter presents values in S7 or S5 format with 12-bit resolution plus sign and selectable 16.7 or 20 ms integration. Matching the integration time to 50 or 60 Hz interference suppression helps the 6ES7144-1JB31-0XB0 reject mains-frequency noise on the shielded sensor cable.

        Channel-level diagnostics on 6ES7144-1JB31-0XB0 include wire-break, overflow and underflow information together with upper- and lower-limit alarms. The IP66/IP67 field module uses M12 connectors, so the enclosure seal, connector coding and shield path must be preserved when it is replaced in an installed ET 200X node.

        Technical notes
        Siemens 6ES7144-1JB31-0XB0 is the Pt100 RTD version of the EM 144 analog expansion family. Confirm the 2-, 3- or 4-wire sensor circuit and channel limits before reproducing the stored ET 200X parameters.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        How do I avoid ordering the wrong EM 144 variant instead of 6ES7144-1JB31-0XB0?
        Confirm that the application uses two Pt100 RTD inputs; 6ES7144-1JB31-0XB0 is the RTD version, not the EM 144 voltage or current-input version.
        Which lead arrangement should be reproduced when replacing 6ES7144-1JB31-0XB0?
        Photograph and match the existing two-, three- or four-wire Pt100 circuit before moving it to 6ES7144-1JB31-0XB0 because each arrangement uses a different measurement-lead relationship.
        What setting on 6ES7144-1JB31-0XB0 helps suppress mains-frequency interference?
        Choose the 16.7 or 20 ms integration setting on 6ES7144-1JB31-0XB0 to align conversion with 60 or 50 Hz interference suppression.
        Why can 6ES7144-1JB31-0XB0 show a limit alarm even when the module remains connected?
        Upper and lower limit alarms on 6ES7144-1JB31-0XB0 are channel value events; they are separate from wire-break, overflow and underflow diagnostic messages.
        What must remain sealed after exchanging 6ES7144-1JB31-0XB0 in the field?
        The housing interfaces and 4/5-pin M12 connector seals of 6ES7144-1JB31-0XB0 must be restored correctly to retain the documented IP66/IP67 protection.
        How far can a shielded Pt100 cable run from 6ES7144-1JB31-0XB0?
        The Siemens data sheet limits the shielded sensor cable connected to 6ES7144-1JB31-0XB0 to 30 m, so longer routes require a different approved measurement architecture.
