        Overview Manuals Input Signals Channel Wiring Backplane Data Timing & Status

        Features:

        • Eight Type 1 inputs acquire 24 V DC states from connected two-wire sensors.
        • The module maps all eight channel states into one input byte on the ET 200S backplane.
        • Green LEDs indicate channel state while galvanic separation isolates the input group from the backplane.
        Siemens 6ES7131-4BF00-0AA0 turns eight field voltage states into the digital byte read by the station interface.

        The input channels of 6ES7131-4BF00-0AA0 share their field-side potential but remain isolated as a group from the backplane bus.

        Isochronous operation aligns the acquisition timing of 6ES7131-4BF00-0AA0 with the configured automation cycle.

        The Siemens 6ES7131-4BF00-0AA0 ET 200S 8-Channel 24 V DC Digital Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.

        Eight 24 V DC Sensor Channels

        • Signal 0: Input voltages from -30 to +5 V are interpreted as the low state.
        • Signal 1: Input voltages from +15 to +30 V are interpreted as the high state.
        • Input current: A high-state channel draws approximately 5 mA.
        • Input delay: Both signal transitions use the documented 2 to 4.5 ms delay range.

        Field Potential and Cable Reach

        • Sensor type: Two-wire sensors can be connected within the stated quiescent-current limit.
        • Shared potential: The eight input channels are not galvanically separated from one another.
        • Shielded cable: A shielded input circuit may extend to 1,000 m.
        • Unshielded cable: An unshielded input circuit is limited to 600 m.

        Address and Isolation Path

        • Input image: All eight channel states occupy one byte in the controller input area.
        • Electronics supply: The module draws up to 10 mA from the 3.3 V DC backplane bus.
        • Group isolation: The complete input group is galvanically separated from the backplane.
        • Proof test: The isolation path is tested at 500 V DC.

        Synchronized Acquisition and Indication

        • Isochronous mode: The terminal-to-backplane acquisition path supports synchronized operation.
        • TWE value: The documented input time for isochronous operation is 3,000 µs.
        • Channel LEDs: One green LED reports the signal state of each digital input.
        • Diagnostic limit: The module does not send diagnostic messages for channel faults.
        Description
        Siemens 6ES7131-4BF00-0AA0 is an eight-channel digital input electronic module for the SIMATIC ET 200S distributed I/O system. It reads 24 V DC signals from two-wire sensors and places the eight channel states into one input byte for transfer through the station backplane.

        Each input of 6ES7131-4BF00-0AA0 recognizes the documented voltage ranges for signal 0 and signal 1. The channels share the field-side potential rather than being isolated from one another, while galvanic separation keeps the complete input group apart from the backplane bus.

        Power for the electronics of 6ES7131-4BF00-0AA0 comes from the 3.3 V DC backplane connection. The module does not provide a sensor-supply output, so sensor power and the 24 V input reference must be arranged through the ET 200S terminal and power-module structure.

        Green channel LEDs on 6ES7131-4BF00-0AA0 show the state of the individual inputs, but the module does not generate diagnostic messages. Isochronous operation can synchronize the acquisition path to the automation cycle, with the documented terminal-to-backplane timing applied to the eight channels.

        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
        Why can a sensor remain ON after the circuit opens on 6ES7131-4BF00-0AA0?
        Check whether the two-wire sensor leakage stays below the 1.5 mA limit of 6ES7131-4BF00-0AA0 and verify the field reference wiring.
        How is 6ES7131-4BF00-0AA0 represented in the controller input image?
        All eight channels of 6ES7131-4BF00-0AA0 occupy one input byte, so the configured start address determines the corresponding input bits.
        Why can the LEDs on 6ES7131-4BF00-0AA0 show states without a diagnostic alarm?
        The 6ES7131-4BF00-0AA0 provides green channel-status LEDs but does not implement diagnostic messages, so controller diagnostics remain empty for channel faults.
        What should be checked when long sensor cables feed 6ES7131-4BF00-0AA0?
        Keep 6ES7131-4BF00-0AA0 sensor wiring within 1,000 m when shielded or 600 m when unshielded, and verify the signal voltage at the input.
        Are the eight channels of 6ES7131-4BF00-0AA0 individually isolated?
        No. The 6ES7131-4BF00-0AA0 channels share field-side potential, while the complete group is isolated from the ET 200S backplane.
        What determines synchronized input timing for 6ES7131-4BF00-0AA0?
        The ET 200S station configuration must enable isochronous operation, after which 6ES7131-4BF00-0AA0 uses the documented 3,000 µs input time.
