        More Information

        Overview Manuals PA Spur Layout DIQ Assignment Supply Continuity Enclosure Entry

        Features:

        • The enclosure bundle combines eight PROFIBUS PA spurs with eight configurable DIQ channels.
        • A two-port PROFINET BusAdapter path supports both MRP media redundancy and S2 system redundancy.
        • The IP66 aluminum housing arrives with cable glands, shield busbar, and shield terminals installed.
        The field unit concentrates PA instruments and conventional digital signals at one distributed process-I/O node.

        Separate spur supervision reports PA line state while input, output, and supply LEDs identify the condition of the digital side.

        Redundant 24 V DC feeds preserve the field-device and communication path across the documented five-millisecond voltage interruption.

        The Siemens 6ES7655-5PX11-1AX0 SIMATIC CFU PA Bundle may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Fieldbus branch organization

        • Eight branches: Each spur provides one PA field-device connection rather than sharing a digital channel terminal.
        • Power and data: The spur pair carries the 31.25 kbit/s PA signal together with the limited field-device supply.
        • Fault containment: A short-circuit-proof spur restricts a branch fault from consuming the entire field-device output.
        • Status feedback: Dedicated spur indicators distinguish line condition from the CFU's PROFINET status.

        Digital channel roles

        • Selectable direction: Each of the eight DIQ points is parameterized as an input or a current-sourcing output.
        • Input sensing: Input mode evaluates 24 V field signals with IEC 61131 Type 1 or Type 3 characteristics.
        • Output switching: Output mode drives a DC load while electronic short-circuit monitoring supervises the channel.
        • Counter option: One selected input can count rising events at up to 1 kHz using a 32-bit upward counter.

        Power distribution and buffering

        • Dual feeds: Two 24 V DC connections allow redundant supply wiring to the enclosed assembly.
        • Protected input: Reverse-polarity and short-circuit protection guard the electronics supply path.
        • Brief interruption: Stored energy maintains field devices and communication for the specified five milliseconds.
        • Thermal derating: The permitted aggregate output current decreases as the horizontal ambient approaches 60 °C.

        Cable and shield arrangement

        • Preassembled body: The CFU is mounted inside the aluminum enclosure before delivery.
        • Cable glands: Field and network cables enter through the fitted gland positions rather than an open terminal frame.
        • Shield path: The busbar and shield terminals provide a defined landing point for cable screens.
        • Mounting choice: Horizontal and vertical positions are supported, with separate temperature limits for each orientation.
        Description
        Siemens 6ES7655-5PX11-1AX0 is a SIMATIC CFU PA field-unit bundle supplied preassembled in an aluminum enclosure with cable glands, a shield busbar, and shield terminals. Within the SIMATIC process I/O architecture, it brings field connections into a PROFINET-connected distributed station.

        Eight spur connections on 6ES7655-5PX11-1AX0 carry PROFIBUS PA communication and power to as many as eight field devices. Each Type A spur can extend to 120 m, while the field-device outputs share a 320 mA total limit with 40 mA current limitation per device.

        The other eight channels of 6ES7655-5PX11-1AX0 are configurable as digital inputs or transistor outputs. Input mode accepts IEC 61131 Type 1 or Type 3 characteristics, and one channel can be parameterized as a 1 kHz, 32-bit up counter; output mode supplies current-sourcing 24 V DC switching at 0.5 A per channel.

        At the controller side, 6ES7655-5PX11-1AX0 operates as a PROFINET IO device through a two-port BusAdapter interface. MRP media redundancy, S2 system redundancy, LLDP, extended fieldbus diagnostics, and channel-status LEDs separate network supervision from the attached PA and DIQ field circuits.

        Two 24 V DC feeds can provide redundant power to 6ES7655-5PX11-1AX0, with reverse-polarity and short-circuit protection included. The IP66 enclosure supports horizontal or vertical mounting; horizontal operation extends from -40 to 60 °C subject to the documented output-current derating.
