        More Information

        Overview Manuals Echo Processing Output Logic Communication Wall Wiring

        Features:

        • Two ultrasonic channels provide continuous non-contact level measurement through compatible Siemens transducers.
        • The selected wall-mount version includes four M20 cable glands, 100 to 230 V AC input, and three relay outputs.
        • Built-in RS 485 Modbus communication operates independently of the echo-measurement wiring.
        Each measuring point on Siemens 7ML5033-1BA10-1A sends an excitation pulse to its transducer and receives the echo required to calculate level.

        Temperature correction and false-echo processing in 7ML5033-1BA10-1A stabilize the value before the controller updates its display, current output, and assigned relays.

        Programming access for 7ML5033-1BA10-1A can use the handheld interface, SIMATIC PDM, or Dolphin Plus without converting the two-point hardware into a different order-code variant.

        The Siemens 7ML5033-1BA10-1A MultiRanger 100 Dual-Point Ultrasonic Level Controller may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
        Siemens 7ML5033-1BA10-1A MultiRanger 100 Dual-Point Ultrasonic Level Controller Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

        From Transducer Pulse to Level Value

        • Excitation path: The controller drives compatible 44 kHz ultrasonic transducers from the dedicated terminals.
        • Return path: Received echoes are evaluated to determine the distance between the transducer face and the material surface.
        • False echoes: Auto False-Echo Suppression separates fixed obstructions from the intended material echo.
        • Compensation: Integral, external TS-3, or fixed-temperature compensation corrects the acoustic calculation.

        Measured Value and Switching Paths

        • Current signal: The isolated output converts the calculated level to a configured 0-20 mA or 4-20 mA signal.
        • Relay group: Two Form A contacts and one Form C contact execute assigned alarm or pump-control functions.
        • Discrete override: The DC discrete input can receive a separate switching state for configured control logic.
        • Load boundary: The analog output is specified for a maximum isolated load of 750 ohms.

        Programming and Data Interfaces

        • RS 485: Terminal-strip communication carries Modbus RTU or Modbus ASCII traffic.
        • RS 232: The RJ11 service connection provides the second documented serial communication path.
        • PDM access: SIMATIC PDM can parameterize the controller through the supported communication route.
        • Local access: The handheld programmer changes parameters through the front programming interface.

        Enclosure, Cable Entries and Shields

        • Enclosure choice: This order suffix selects wall mounting with four supplied M20 cable glands.
        • Transducer cable: Use shielded twisted two-core copper cable for the ultrasonic signal path.
        • Shield termination: Cable shields terminate at the controller shield points and remain isolated from additional earth connections.
        • Separation: Transducer and signal wiring should be routed separately from power conductors to limit noise pickup.
        Description
        Siemens 7ML5033-1BA10-1A is a MultiRanger 100 dual-point ultrasonic level controller for continuous, non-contact measurement. It excites compatible EchoMax or ST-H transducers, evaluates their return echoes, and converts the two measuring paths into level values, alarm states, and basic pump-control decisions.

        The order-code structure of 7ML5033-1BA10-1A selects a wall-mount enclosure with four M20 cable entries, a 100 to 230 V AC supply, dual-point operation, and no installed SmartLinx option. Three output relays provide two Form A contacts and one Form C contact for configured switching functions.

        Signal wiring on 7ML5033-1BA10-1A keeps transducer, discrete-input, analog-output, relay, and RS 485 circuits on separate terminal groups. Shielded two-core transducer cable can extend the measurement path to 365 m, while the built-in Modbus interface carries configuration or process data independently of the echo channel.

        During measurement, 7ML5033-1BA10-1A applies temperature compensation and false-echo suppression before generating its 0/4 to 20 mA output. The display and handheld, SIMATIC PDM, or Dolphin Plus programming paths expose measured values and parameter settings without changing the physical transducer connection.

        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 can a buyer distinguish the dual-point 7ML5033-1BA10-1A from adjacent MultiRanger 100 variants?
        The full suffix of Siemens 7ML5033-1BA10-1A identifies dual-point measurement, four M20 entries, AC supply, and no SmartLinx module; verify the complete nameplate before replacement.
        Why must the relay contact types be checked before wiring 7ML5033-1BA10-1A into an alarm or pump circuit?
        Siemens 7ML5033-1BA10-1A provides two Form A relays and one Form C relay, so the selected terminals and normal contact state must match the control circuit.
        What should be inspected when the echo value on 7ML5033-1BA10-1A becomes unstable after field wiring?
        Check that 7ML5033-1BA10-1A uses shielded twisted two-core transducer cable, controller-side shield termination, separation from power wiring, and no more than 365 m of cable.
        Can a technician assume that a SmartLinx card is installed when configuring 7ML5033-1BA10-1A?
        No. The order code of 7ML5033-1BA10-1A specifies operation without an installed SmartLinx module, so communication must use the documented built-in interfaces.
        Why can the analog receiver connected to 7ML5033-1BA10-1A read low or saturate?
        Verify the 0/4-20 mA scaling, polarity, and total loop load for 7ML5033-1BA10-1A; the isolated output supports no more than 750 ohms.
        What should be verified if 7ML5033-1BA10-1A does not power up after installation?
        Confirm that 7ML5033-1BA10-1A receives 100-230 V AC at 50/60 Hz on its AC input terminals; the 12-30 V DC supply belongs to a different variant.
