        Overview Manuals Signal Chain HART Handling Safety Logic Ex Installation

        Features:

        • Four fail-safe current inputs accept HART two-wire transmitters in an ET 200iSP station.
        • PROFIsafe communication carries safety-related channel data to the control system.
        • Channel diagnostics report wire-break and short-circuit conditions to the configured project.
        Each field loop combines transmitter power and a measured current signal on the documented two-wire connection.

        The integrating conversion path and four smoothing stages let the project control how quickly stable values are presented.

        Intrinsic-safety limits, terminal assignment and enclosure conditions remain part of the station-level Ex design.

        The Siemens 6ES7138-7FA00-0AB0 ET 200iSP 4F-AI HART Ex I Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        From transmitter current to safe process value

        • Field loop: A HART two-wire transmitter uses the same loop for power and the 0/4 to 20 mA measurement signal.
        • Input conversion: The module applies integrating Sigma-Delta conversion and produces a signed 16-bit value.
        • Controller image: Twelve input bytes carry channel information while four output bytes support module communication.
        • Isolation boundary: The analog input path is separated from the backplane bus and the Powerbus load-voltage path.

        HART channel handling

        • Protocol level: The module supports HART protocol version 7.0 for connected two-wire transmitters.
        • Cable reach: Shielded signal cable may extend to 500 m under the documented wiring conditions.
        • Transmitter burden: The permitted burden for a two-wire transmitter is 750 ohm maximum.
        • Value smoothing: None, low, medium and high smoothing correspond to 1, 4, 16 and 64 cycle times.

        Safety and diagnostic behavior

        • Safety ceiling: The module is certified for SIL 3, Performance Level e and Category 4 operation.
        • Fault reporting: Diagnostic alarms can be parameterized for the safety project.
        • Loop faults: Wire-break and short-circuit states are available as diagnostic information.
        • Potential difference: Different circuit groups permit up to 60 V DC or 30 V AC potential difference.

        Hazardous-area installation checks

        • Ex role: The module is associated equipment for Ex ia and Ex ib circuits within the stated certification scope.
        • Gas area: The documentation covers ATEX gas Zone 1 use under the listed marking.
        • Dust area: Zone 21 dust use requires installation in the corresponding enclosure.
        • Termination: Use the specified screw or spring-type terminal system and preserve the approved shield arrangement.
        Description
        The Siemens 6ES7138-7FA00-0AB0 is a SIMATIC ET 200iSP 4F-AI HART Ex I fail-safe analog input module. It connects four intrinsically safe HART two-wire transmitters to the station and carries their measured current values into the PROFIsafe-controlled automation path.

        Across its four channels, 6ES7138-7FA00-0AB0 accepts either 0 to 20 mA or 4 to 20 mA signals and converts them with an integrating Sigma-Delta method at up to 16-bit resolution including sign. Parameterizable smoothing lets each measurement path trade response speed for additional stability without changing the transmitter wiring principle.

        The 6ES7138-7FA00-0AB0 supplies connected transmitters through a short-circuit-proof path and supports shielded cable runs up to 500 m. Diagnostic alarms, readable diagnostic information, wire-break detection and short-circuit detection give the controller a defined indication when the field loop or channel path is no longer valid.

        For safety and hazardous-area engineering, 6ES7138-7FA00-0AB0 is documented up to SIL 3, Performance Level e and Category 4. The analog channels are separated from the backplane bus and load-voltage path, while installation must follow the stated Ex marking, enclosure and terminal requirements for the target ET 200iSP station.

        Technical notes
        Siemens 6ES7138-7FA00-0AB0 accepts current signals from HART two-wire transmitters only. Its safety parameters and hazardous-area installation conditions must be assigned in the ET 200iSP project before commissioning.

        VIEW ALL FAQS
        Which transmitter wiring does 6ES7138-7FA00-0AB0 accept?
        The 6ES7138-7FA00-0AB0 is designed for HART two-wire current transmitters using 0 to 20 mA or 4 to 20 mA input ranges; it is not the voltage, thermocouple or RTD variant.
        Can 6ES7138-7FA00-0AB0 keep HART data while participating in a safety loop?
        Yes. 6ES7138-7FA00-0AB0 supports HART protocol version 7.0 for the field devices and PROFIsafe for the safety-related station communication.
        What should be checked when a long field cable is connected to 6ES7138-7FA00-0AB0?
        Confirm shield continuity, loop burden and the 500 m maximum shielded-cable limit; 6ES7138-7FA00-0AB0 allows a two-wire transmitter burden of up to 750 ohm.
        How does 6ES7138-7FA00-0AB0 expose a broken or shorted field loop?
        The configured diagnostic path of 6ES7138-7FA00-0AB0 can report wire-break and short-circuit conditions and issue a parameterizable diagnostic alarm.
        Why is the output area present on the input module 6ES7138-7FA00-0AB0?
        The 16-byte address allocation of 6ES7138-7FA00-0AB0 consists of 12 input bytes and 4 output bytes so the station can exchange both measured and module-related communication data.
        Before placing 6ES7138-7FA00-0AB0 in a hazardous area, what documentation must agree?
        The 6ES7138-7FA00-0AB0 Ex marking, terminal assignment, enclosure, associated-equipment limits and the ET 200iSP safety project must all match the intended zone and field circuit.
