        Features:

        • All-DC platform: 24 V DC controller supply and sinking or sourcing inputs
        • Mixed output bank: two relay contacts plus four FET outputs
        • Lifecycle boundary: officially discontinued with no planned Rockwell Automation replacement
        1763-L16BBB fits MicroLogix 1100 systems that need DC power, mixed solid-state and contact outputs, and small analog monitoring capability.

        Its terminal map matters more than a simple output total because relay and FET points have different electrical behavior and application limits.

        A sustainable record ties the exact BBB suffix to the project, hardware and firmware, output assignments, network settings, analog references, expansion bank, and validated machine behavior.
        Apter Power can coordinate official-document checks, quotation, and sourcing support for 1763-L16BBB.

        • Relay points: use contact outputs where the approved load and isolation design require relay behavior.
        • FET points: verify DC polarity, leakage, return path, and switching duty for each solid-state load.
        • Acceptance: prove commanded, off-state, and fault-state behavior separately for both output technologies.
        • Source quality: provide a qualified 24 V DC Class 2 SELV source with sufficient startup and load-transient performance.
        • Return voltage: measure controller and field returns during simultaneous switching so cable drop is not mistaken for logic failure.
        • Power separation: document which circuits supply logic, analog devices, relays, and FET loads before commissioning.
        • Ethernet record: retain IP settings, peer message definitions, routing, and timeout behavior.
        • Serial record: preserve the isolated channel protocol, cabling, node settings, and recovery mode.
        • Expansion record: capture Bulletin 1762 module catalogs, order, and current loading with the tested project archive.
        • DC machine control: supervise sinking or sourcing sensors and switch qualified FET or relay loads.
        • Compact analog monitoring: acquire two voltage signals alongside discrete machine logic.
        • Installed-system sustainment: maintain documented MicroLogix 1100 equipment where no planned OEM replacement is published.
        Description
        1763-L16BBB is the 24 V DC powered MicroLogix 1100 configuration. It combines ten sinking or sourcing DC inputs, two voltage inputs, two relay outputs, and four FET outputs with isolated Ethernet, isolated serial communication, an LCD, and local Bulletin 1762 expansion.

        The mixed output architecture of 1763-L16BBB separates contact isolation from solid-state switching behavior, while its analog channels use non-isolated ten-bit data. Power-return design, output assignment, analog reference, shielding, load suppression, and expansion current must therefore be verified as distinct engineering tasks.

        Rockwell Automation marks 1763-L16BBB discontinued with no planned Rockwell Automation replacement. A maintenance strategy should preserve the project, hardware series, firmware, terminal map, network configuration, output technology assignments, expansion inventory, and acceptance-test record before any cross-platform redesign.

        Technical notes
        Because 1763-L16BBB combines two relay outputs with four FET outputs, a relay-only terminal schedule can create polarity, leakage, suppression, and switching errors. Reconcile every programmed point with the official layout, mark output technology on the drawing, and suspend energization whenever the field wiring conflicts with that map.

        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 DC load remain faintly energized when commanded off by 1763-L16BBB?
        Identify whether the point is FET or relay, measure off-state leakage and return voltage under the real load, and use a qualified interface if the load cannot tolerate solid-state leakage.
        How should 1763-L16BBB power stability be checked when outputs switch simultaneously?
        Trend 24 V at the controller terminals, inspect source inrush capacity and return drop, separate field-load transients, and correlate voltage with fault and status indications.
        What is the safest way to move a relay load to a FET point on 1763-L16BBB?
        First confirm load voltage, polarity, steady and inrush current, leakage tolerance, suppression, and switching duty; then update the terminal schedule and prove off, on, and fault states.
        Why can an analog input on 1763-L16BBB disagree with a handheld meter?
        Compare the measurement reference with IA COM, inject a known voltage, inspect shield grounding and field supply, and review raw ten-bit counts before modifying scale or calibration.
        How should a plant plan beyond discontinued 1763-L16BBB when Rockwell Automation lists no planned replacement?
        Preserve a tested project and spare strategy, document every I/O and protocol dependency, then perform a requirements-led migration study rather than assigning an unofficial drop-in substitute.
        How can a buyer confirm that 1763-L16BBB has the required FET output hardware before dispatch?
        Request clear catalog, series, power, and output-terminal photographs; reconcile the four FET and two relay positions with the project schedule, then record condition, quantity, and destination only after the terminal map agrees.
