Product Details

1769-L24ER-QBFC1BK Product Description

The Allen-Bradley 1769-L24ER-QBFC1BK is a CompactLogix 5370 L2 series programmable logic controller engineered for energy-aware industrial automation. Combining deterministic EtherNet/IP communication with a compact, DIN-rail-mountable form factor, this controller delivers precise execution of energy-control strategies across motor-driven production lines, packaging systems, conveyor networks, and process automation cells. With its integrated dual EtherNet/IP ports, embedded I/O, and support for CIP Motion and CIP Energy extensions, the 1769-L24ER-QBFC1BK is purpose-built to reduce idle-state power draw, eliminate unnecessary actuator cycling, and maintain stable production throughput — all within a unified Logix control architecture.

Effective energy management in a modern production facility depends on tight coordination between the controller layer and every downstream device it governs. The 1769-L24ER-QBFC1BK achieves this through its native EtherNet/IP backbone, which enables real-time data exchange with PowerFlex 525 and PowerFlex 755 variable-frequency drives — allowing the PLC to issue speed-reference commands that match actual load demand rather than running motors at fixed full speed. This alone can reduce motor energy consumption by 20–50% in variable-torque applications such as fans, pumps, and conveyors.

On the motion side, the controller integrates seamlessly with Kinetix 5500 servo drives via CIP Motion, enabling coordinated multi-axis positioning with regenerative braking energy recovery. When a servo axis decelerates, the Kinetix 5500 can feed recovered energy back into the DC bus shared with adjacent drives, reducing net energy draw from the supply rail. The 1769-L24ER-QBFC1BK orchestrates these energy-recovery windows through its motion task scheduler, ensuring deceleration events are timed to coincide with adjacent acceleration demands on the same bus segment.

Power quality and consumption visibility are provided by integrating the controller with a PowerMonitor 5000 power-measurement module via EtherNet/IP. The PowerMonitor 5000 streams real-time kW, kVAR, power factor, and harmonic distortion data directly into the Logix tag database, where the 1769-L24ER-QBFC1BK can execute load-shedding logic — automatically de-energising non-critical outputs when demand exceeds a configurable threshold. This closed-loop energy strategy is far more responsive than manual intervention and eliminates demand-charge spikes on utility billing.

The controller's embedded 16-point DC input bank connects directly to SICK or Balluff inductive proximity sensors and photoelectric sensors positioned at key conveyor transfer points. By monitoring part-presence signals, the PLC can suppress conveyor drive output during gap periods — a technique known as zone-based energy control — rather than running the belt continuously. Combined with 1769-IQ16 and 1769-OB16 expansion I/O modules for additional sensor and actuator channels, the system scales to cover multi-zone conveyor networks without adding a second controller.

For operator visibility and energy KPI display, the 1769-L24ER-QBFC1BK communicates with a PanelView Plus 7 HMI terminal over EtherNet/IP. The HMI presents real-time energy dashboards — current draw per zone, cumulative shift consumption, and drive efficiency ratings — giving line supervisors actionable data to adjust production scheduling and reduce off-peak idle time. At the SCADA level, FactoryTalk Energy Metrics aggregates controller-reported CIP Energy state data across multiple 1769-L24ER-QBFC1BK nodes on the plant network, enabling site-wide energy benchmarking and ISO 50001 compliance reporting.

The 1769-L24ER-QBFC1BK addresses the four primary sources of energy waste in discrete manufacturing: unnecessary motor runtime, uncontrolled inrush current, thermal overload from poor load matching, and idle-state actuator energisation. Its programmable task structure — with periodic, event-driven, and continuous task types — allows engineers to implement energy-state machines that transition equipment through defined power modes: Running, Standby, Ready, and Off. These states map directly to the PackML state model, ensuring compatibility with broader MES and ERP energy-reporting frameworks.

Drive speed optimisation is one of the highest-impact strategies enabled by this controller. By reading throughput data from upstream vision systems or barcode scanners via EtherNet/IP and adjusting PowerFlex drive speed references in real time, the 1769-L24ER-QBFC1BK ensures that conveyor and indexing systems run only as fast as downstream buffer capacity allows. This eliminates the energy waste of running at maximum speed into a blocked station — a common source of both excess consumption and mechanical wear.

Thermal load management is equally important in enclosed control panels and machine enclosures. The controller's deterministic scan cycle and low self-consumption (approximately 4.5 W) minimise heat generation at the controller level. When paired with 1769-ECR right-end caps and properly rated 1769-PA2 or 1769-PB2 power supplies, the CompactLogix system maintains stable thermal performance across the full 0–60 °C operating range without requiring supplemental cooling — reducing HVAC energy demand in the control cabinet itself.

Predictive maintenance integration further extends energy efficiency gains. By logging drive current signatures, motor run-hours, and fault histories into FactoryTalk Historian via the EtherNet/IP network, the 1769-L24ER-QBFC1BK enables condition-based maintenance scheduling. Replacing a degraded motor bearing before it causes increased friction — and therefore increased current draw — prevents the gradual energy creep that often goes unnoticed until a catastrophic failure occurs. This proactive approach reduces both unplanned downtime and the energy penalty of running degraded equipment.

All units supplied by NANKMOS are sourced from authorised distribution channels, subjected to functional power-on testing, communication verification, and I/O continuity checks prior to shipment. Stock is maintained for immediate dispatch, with lead times confirmed at order placement. Each 1769-L24ER-QBFC1BK is covered by a 12-Month Warranty against manufacturing defects and operational failure under normal industrial service conditions.

Q1: How much energy can the 1769-L24ER-QBFC1BK help save on a typical conveyor line?Energy savings depend on the application, but zone-based motor control strategies implemented through this PLC — combined with PowerFlex VFD speed optimisation — commonly achieve 15–40% reductions in conveyor drive energy consumption compared to fixed-speed, always-on configurations. Actual results depend on line layout, throughput variability, and the number of controlled zones.

Q2: Is the 1769-L24ER-QBFC1BK compatible with existing CompactLogix programs and expansion modules?Yes. The 1769-L24ER-QBFC1BK is fully compatible with the 1769 Compact I/O module family, including 1769-IQ16, 1769-OB16, 1769-IF4, and 1769-OF2 analogue modules. Existing Studio 5000 Logix Designer projects targeting CompactLogix 5370 L2 controllers can be imported with minimal revision. Firmware upgrades are managed through ControlFLASH or Studio 5000.

Q3: What is the recommended replacement or upgrade path from an older CompactLogix controller?For sites running 1769-L23E or 1769-L20 series controllers, the 1769-L24ER-QBFC1BK offers a direct form-factor upgrade with expanded memory, dual EtherNet/IP ports, and CIP Energy support not available on legacy L2 variants. Program migration is supported via Studio 5000 import tools, and the embedded I/O eliminates the need for a separate starter I/O module in many retrofit applications.

Q4: What does the 12-Month Warranty cover, and how is the pre-shipment test conducted?The 12-Month Warranty covers all manufacturing defects and functional failures under normal industrial operating conditions from the date of shipment. Pre-shipment testing includes power-on verification, EtherNet/IP port communication check, embedded I/O functional test, and firmware version confirmation. A test report is available upon request.
