        Overview Manuals 16-Bit I/O Noise Filter Input Safety Diff Wiring

        Features:

        • Provides four differential current inputs.
        • Supports ±20 mA, 0–20 mA and 4–20 mA ranges.
        • Delivers 16-bit conversion with selectable 50/60 Hz rejection.
        Horner HE800ADC140 is the metal-case four-channel 16-bit SmartStack current input ordering configuration.

        The module accepts common industrial current signals for higher-resolution monitoring in compatible controller applications.

        Range selection, conversion timing, common-mode voltage and differential field wiring must be checked during system integration.

        The Horner HE800ADC140 Current Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
        Horner HE800ADC140 Current Input Module Manuals, Datasheets, Links 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.

        HE800ADC140 16-Bit I/O

        • Input structure: Four differential current channels are provided in one SmartStack module.
        • Range choices: Supported selections are ±20 mA, 0–20 mA and 4–20 mA.
        • Resolution: Current data is represented with 16-bit conversion.
        • Conversion cycle: All four channels complete conversion in 313 ms.
        • Input resistance: The published impedance is 5 Ω.

        HE800ADC140 Noise Filter

        • Cscape monitoring: The software provides access to module status during setup.
        • Independent selection: Any supported current range can be chosen separately for each channel.
        • Digital filter: The Filter Constant changes the response applied to the measured signal.
        • Mains rejection: A 50 Hz or 60 Hz setting is available for line-frequency noise rejection.
        • I/O placement: Register assignments follow the model number and SmartStack location rather than manual editing.

        HE800ADC140 Input Safety

        • Common-mode boundary: Differential inputs must remain within the specified ±12 VDC range.
        • Out-of-range effect: Exceeding that boundary produces incorrect readings on the affected channel.
        • Reference connection: Leaving one side of a differential input unconnected results in an effective zero reading.
        • Reversed pair: Swapping differential polarity reverses the sign of the PLC data.
        • Current ceiling: The maximum overcurrent rating is 100 mA.

        HE800ADC140 Diff Wiring

        • Channel conductors: Each loop uses positive, negative and shield terminals.
        • Common reference: One side of every input may be tied to the OCS supply common to hold the required common-mode range.
        • Cable pairing: Twisted pairs are required, with shielding preferred for analog signal quality.
        • Connector hardware: The field block is removable and uses spring-clamp terminals.
        • Module supply: Steady-state consumption is 0.62 W at 24 VDC, with no external input supply required.
        Description
        Horner HE800ADC140 is the four-channel, 16-bit metal-case SmartStack current input configuration. Its selectable ±20 mA, 0–20 mA and 4–20 mA ranges support common industrial current-signal formats on one module.

        The HE800ADC140 converts all four channels in 313 ms and transfers values to the controller during the PLC scan. Channel-specific filtering and selectable 50 or 60 Hz rejection help commissioning teams adapt measurement behavior to the electrical environment.

        The HE800ADC140 uses differential inputs with a specified ±12 VDC common-mode limit. Correct polarity, shared common-mode conditions, shielded wiring and the SmartStack power budget must be verified before connecting field loops.

        Technical notes
        Horner HE800ADC140 provides four differential 16-bit SmartStack current inputs for ±20 mA, 0–20 mA and 4–20 mA signals. It supports per-channel filtering and 50/60 Hz rejection.

        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 I reduce mains-frequency noise on Horner HE800ADC140 readings?
        Horner HE800ADC140 provides selectable 50 Hz or 60 Hz rejection and per-channel digital filtering. Match rejection to the local supply frequency and verify shield routing.
        Why does a 4–20 mA transmitter read incorrectly on Horner HE800ADC140?
        Confirm that the Horner HE800ADC140 channel is configured for 4–20 mA, check loop polarity and verify that the differential input remains within the ±12 VDC common-mode limit.
        Can Horner HE800ADC140 channels use different current ranges?
        Yes. Horner HE800ADC140 allows ±20 mA, 0–20 mA or 4–20 mA to be selected independently for each channel.
        Why does Horner HE800ADC140 data update more slowly than the PLC scan?
        Horner HE800ADC140 requires 313 ms to convert all four channels. The controller scan transfers the latest available values but does not shorten the conversion interval.
        What wiring issue can affect several Horner HE800ADC140 inputs at once?
        Horner HE800ADC140 uses differential inputs, so an incorrect common reference or common-mode voltage outside ±12 VDC can disturb multiple connected loops.
        What should I verify before replacing another current module with Horner HE800ADC140?
        Compare channel count, 16-bit scaling, range selection, 313 ms conversion time, terminal wiring and SmartStack compatibility before using Horner HE800ADC140.
