        Overview Manuals Current Loops Channel Setup Field Wiring Platform Fit

        Features:

        • Connects four current-loop signals.
        • Supports individual bipolar or unipolar channel ranges.
        • Provides 12-bit measurement with selectable digital filtering.
        Designed around four current loops, Horner HE800ADC120 places multichannel measurement in one metal SmartStack module.

        Independent range and filter choices allow unlike field signals to share the module while remaining distinct in the controller input map.

        Review the per-channel loop polarity, the 24 VDC SmartStack power budget and cable shielding when the I/O plan is commissioned.

        The Horner HE800ADC120 Current Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
        Horner HE800ADC120 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.

        HE800ADC120 Current Loops

        • Loop count: Four analog current channels feed four input points in the controller.
        • Measurement modes: Each loop accepts either 0–20.47 mA or ±20.47 mA.
        • Signal conversion: A 12-bit successive-approximation stage converts the incoming current.
        • Electrical loading: The input is 100 Ω below 12 VDC and is clamped at 12 VDC.
        • Update timing: New channel values follow the PLC scan rate.

        HE800ADC120 Channel Setup

        • Software workspace: Cscape is used to view I/O status and open the module setup.
        • Range independence: Bipolar and unipolar choices can be assigned without forcing one setting across all four channels.
        • Noise response: Each input has a configurable digital filter constant from 0 to 7.
        • Register allocation: Input words are fixed by the model and its physical location in the SmartStack point map.
        • Engineering conversion: The specified factor for the supported current ranges is 0.000625.

        HE800ADC120 Field Wiring

        • Source options: Official wiring diagrams show both self-powered and non-self-powered 20 mA devices.
        • Four-channel layout: Every loop has a positive input, common and shield terminal assignment.
        • Termination: A removable spring-clamp connector is used for field conductors.
        • Interference control: Shielded twisted pairs help isolate low-level current signals from panel noise.
        • Channel limit: Input current must remain within the 35 mA continuous maximum.

        HE800ADC120 Platform Fit

        • Stack form: HE800ADC120 is supplied in the metal SmartStack configuration.
        • Companion code: HE-ADC120 identifies the plastic-case version listed in the same datasheet.
        • Numbering scope: Matching IC300-prefixed versions are also covered by the manufacturer document.
        • System procedure: The installed controller manual supplies the preliminary SmartStack configuration steps.
        • Power budget: The module uses 0.09 W from 24 VDC and does not call for a separate external input supply.
        Description
        Four field-current loops can be consolidated in one metal SmartStack position with Horner HE800ADC120. Every channel may be assigned either 0–20.47 mA or ±20.47 mA, which supports mixed signal behavior within the same module.

        Rather than applying one filter to all inputs, the HE800ADC120 stores a separate digital filter constant for each channel. Its 12-bit conversion and automatic Cscape I/O mapping make the measured loop values available to compatible controller logic.

        Installation planning should account for four loop circuits, removable spring-clamp terminals and the 35 mA continuous limit on each input. Shielded twisted-pair cable and correct polarity help the HE800ADC120 distinguish field conditions from wiring problems.

        Technical notes
        Four independently configured current loops feed compatible SmartStack systems through Horner HE800ADC120, with 12-bit conversion and selectable filtering.

        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 isolate one noisy loop on a Horner HE800ADC120?
        Horner HE800ADC120 lets each channel use its own digital filter constant. Compare wiring, shielding and grounding on the affected loop before increasing that channel’s filter setting.
        Can Horner HE800ADC120 mix unipolar and bipolar current inputs?
        Yes. Horner HE800ADC120 allows each of its four channels to select 0–20.47 mA or ±20.47 mA independently in Cscape.
        Why does one Horner HE800ADC120 input stay at zero while the others work?
        Check that Horner HE800ADC120 channel for loop continuity, transmitter power, polarity, terminal placement and the selected current range.
        How do I avoid overloading a Horner HE800ADC120 input?
        Keep every Horner HE800ADC120 channel below the specified 35 mA continuous maximum and verify the loop cannot drive an unintended excessive current.
        What must be checked when expanding a system with Horner HE800ADC120?
        Confirm SmartStack metal compatibility, input-register availability, 24 VDC power capacity and the four-channel wiring plan before installing Horner HE800ADC120.
        How should Horner HE800ADC120 measurements be converted for engineering units?
        Horner HE800ADC120 current values use a 0.000625 conversion factor. Apply it to the mapped count with the correct sign for the configured range.
