Product Details

1764-24BWA Product Description

The Allen-Bradley 1764-24BWA is a high-performance MicroLogix 1500 series programmable logic controller engineered for energy-conscious industrial environments. Featuring 24 relay output points and a robust embedded processor, this unit delivers precise load management, real-time device status feedback, and deterministic scan-cycle control — making it a cornerstone component for factories committed to reducing energy waste and maximizing production line throughput. Every unit in our inventory has been pre-shipment tested and verified for operational integrity before dispatch, backed by a 12-Month Warranty.

In modern smart production environments, energy efficiency is not a feature — it is a system-level discipline. The 1764-24BWA MicroLogix 1500 is designed to operate as the central decision node in a power-aware automation architecture. Its relay outputs interface directly with motor starters, contactors, and solenoid valves, enabling the controller to sequence loads with millisecond precision and eliminate the unnecessary energization of downstream devices during idle production windows.

When paired with a PowerFlex 525 or PowerFlex 40 variable frequency drive, the 1764-24BWA enables closed-loop motor speed regulation based on real-time demand signals. Rather than running motors at full speed continuously, the PLC issues speed-reference commands to the drive, reducing motor energy consumption by 20–50% during partial-load conditions — a critical gain in facilities running multi-shift operations. The 1764-LSP base unit, which serves as the processor module for the MicroLogix 1500 platform, works in tandem with the 1764-24BWA I/O chassis to execute ladder logic programs that govern these energy-saving sequences.

For power monitoring and load analytics, the 1764-24BWA integrates seamlessly with PowerMonitor 500 or PowerMonitor 1000 units via DH-485 or Ethernet/IP communication. These power measurement modules feed real-time kW, kVAR, and power factor data back to the PLC, allowing the control program to trigger load-shedding routines when facility demand approaches peak thresholds. This closed-loop energy feedback loop is essential for facilities operating under demand-charge tariff structures.

On the I/O expansion side, the 1769-IQ16 CompactLogix digital input module and 1769-OW16 relay output module can be used alongside the MicroLogix 1500 platform to extend field device connectivity without increasing the controller's base power draw. For analog signal acquisition — such as temperature, pressure, or current loop feedback from field sensors — the 1762-IF4 analog input module provides four-channel 4–20 mA or 0–10 V input capability, enabling the PLC to monitor motor thermal conditions and adjust duty cycles accordingly to reduce heat-related energy losses.

HMI integration is handled through PanelView Component or PanelView Plus terminals connected via DH-485 or Ethernet/IP, giving operators real-time visibility into energy consumption trends, alarm states, and production throughput metrics. When operators can see energy data at the machine level, they are empowered to make informed decisions about shift scheduling, equipment staging, and preventive maintenance — all of which contribute to measurable reductions in per-unit energy cost.

For facilities using SCADA platforms such as FactoryTalk View SE or Ignition, the 1764-24BWA communicates upstream via a 1761-NET-ENI Ethernet interface module or a 1747-SDN DeviceNet scanner, enabling plant-wide energy dashboards that aggregate consumption data across multiple MicroLogix and ControlLogix nodes. This multi-node visibility is the foundation of any credible energy management system (EnMS) aligned with ISO 50001 principles.

Production line energy optimization begins with control-layer precision, and the 1764-24BWA delivers exactly that. By executing tightly sequenced relay output commands, this PLC eliminates the overlap periods where multiple high-draw devices — motors, heaters, pneumatic actuators — are simultaneously energized during transitions between production states. This sequencing discipline alone can reduce peak demand spikes by 10–30% in discrete manufacturing cells.

Thermal load management is another critical dimension. Industrial facilities lose significant energy through heat generated by continuously running motors and drives operating at partial load. The 1764-24BWA, when programmed with demand-based start/stop logic, ensures that motors are only energized when production demand justifies it. Combined with thermal overload relay feedback wired into the PLC's digital inputs, the system can detect early-stage motor heating and reduce duty cycles before thermal runaway occurs — preventing both energy waste and unplanned downtime.

Production line takt time stability is directly linked to controller scan-cycle consistency. The MicroLogix 1500 platform's deterministic execution model ensures that output commands are delivered within predictable time windows, preventing the micro-stoppages and re-start surges that inflate energy consumption in high-cycle-rate assembly lines. Facilities that have migrated from older relay-based control panels to MicroLogix 1500 platforms consistently report improvements in OEE (Overall Equipment Effectiveness) alongside reductions in energy cost per unit produced.

Predictive maintenance integration further extends the energy optimization value of the 1764-24BWA. By logging runtime hours, output cycle counts, and fault event histories through the PLC's data file system, maintenance teams can schedule interventions before equipment degradation leads to efficiency losses. A motor running with worn bearings draws 5–15% more current than a well-maintained unit — catching this early through PLC-logged runtime data translates directly into energy savings and extended asset life.

All units are dispatched from verified inventory, pre-shipment tested under load conditions, and covered by a 12-Month Warranty. Our stock is maintained to support rapid deployment for both planned capital projects and emergency replacement scenarios, minimizing production downtime and ensuring your energy optimization initiatives stay on schedule.

Q1: How does the 1764-24BWA contribute to measurable energy savings on a production line? The 1764-24BWA enables demand-based load sequencing through its 24 relay outputs, ensuring motors, actuators, and heating elements are only energized when production logic requires it. When integrated with variable frequency drives such as the PowerFlex 525 and power monitoring modules such as the PowerMonitor 500, the system creates a closed-loop energy management architecture capable of reducing idle-state energy consumption by 20–40% in typical discrete manufacturing applications.

Q2: Is the 1764-24BWA compatible with existing MicroLogix 1500 base units and expansion I/O? Yes. The 1764-24BWA is a standard MicroLogix 1500 I/O chassis fully compatible with the 1764-LSP and 1764-LRP processor modules, as well as MicroLogix 1500 expansion I/O modules including analog input modules such as the 1762-IF4 and digital I/O modules such as the 1769-IQ16. It also supports communication via DH-485 and Ethernet/IP using interface adapters, enabling integration into existing RSLogix 500 programs without reprogramming the base control logic.

Q3: What is the pre-shipment testing process and what does the 12-Month Warranty cover? Every 1764-24BWA unit undergoes functional verification under simulated load conditions prior to dispatch. Testing confirms relay output switching integrity, processor communication, and power supply stability. The 12-Month Warranty covers manufacturing defects and operational failures under normal industrial use conditions. Replacement or repair is coordinated directly through our support team, with priority handling for production-critical applications.

Q4: Can this unit replace a failed 1764-24BWA in an existing installation without reconfiguration? In most cases, yes. The 1764-24BWA is a direct form-fit-function replacement for existing MicroLogix 1500 installations using the same chassis and I/O configuration. The existing RSLogix 500 program can be downloaded to the replacement unit via the serial programming port or Ethernet/IP interface without modification, provided the firmware version is compatible. Our technical team can advise on firmware alignment and any configuration considerations specific to your installation prior to shipment.
