Product Details

1764-24AWA Product Description

The Allen-Bradley 1764-24AWA is a high-performance MicroLogix 1500 PLC Base Unit engineered for energy-conscious industrial environments. Designed to deliver precise load management, motor control, and real-time device feedback, this controller serves as the central intelligence layer in smart production lines where energy efficiency and uptime are non-negotiable. With 24 I/O points, AC power input, and relay output architecture, the 1764-24AWA integrates seamlessly into a wide range of factory automation topologies — from discrete manufacturing to process control and energy management systems.

In modern industrial facilities, uncontrolled energy consumption is one of the leading contributors to operational cost overruns. The 1764-24AWA addresses this directly by enabling tightly coordinated control loops that reduce idle-state power draw, eliminate unnecessary actuator cycling, and synchronize equipment start-up sequences to minimize inrush current peaks. When deployed alongside Allen-Bradley PowerFlex 40 variable frequency drives, the controller can dynamically adjust motor speed based on real-time load demand — cutting energy consumption by 20–40% on conveyor, pump, and fan applications without sacrificing throughput.

Pre-shipment tested and backed by a 12-month warranty, every 1764-24AWA unit shipped by NANKMOS undergoes functional verification to ensure relay output integrity, communication port responsiveness, and power supply stability before leaving our facility. This commitment to quality assurance reduces commissioning risk and supports predictive maintenance planning from day one.

The 1764-24AWA is purpose-built for integration within layered automation architectures where energy visibility and control precision are equally critical. At the field level, it interfaces directly with Allen-Bradley 1769-IQ16 digital input modules to capture real-time status signals from proximity sensors, limit switches, and current transducers — enabling the controller to make millisecond-level decisions that prevent energy waste from unnecessary actuator engagement.

For motor-driven applications, the 1764-24AWA pairs naturally with Allen-Bradley PowerFlex 525 AC drives via hardwired relay outputs or RS-232 serial communication. This pairing allows the PLC to issue speed reference commands and enable/disable signals based on production demand signals, effectively eliminating the fixed-speed motor operation that accounts for a disproportionate share of factory energy budgets. On packaging and assembly lines, this translates to measurable reductions in kWh per unit produced.

Power quality monitoring is enhanced when the 1764-24AWA is deployed alongside Schneider Electric PowerLogic PM5000 series power meters or equivalent Rockwell Automation 1420 PowerMonitor units. These devices feed real-time power factor, harmonic distortion, and demand data back to the PLC via analog input modules such as the Allen-Bradley 1769-IF4, allowing the controller to trigger corrective actions — such as capacitor bank switching or load shedding — before energy penalties are incurred.

At the HMI layer, the 1764-24AWA communicates with Allen-Bradley PanelView Component C600 terminals over DH-485, providing operators with live energy dashboards, alarm acknowledgment interfaces, and manual override capability. This visibility layer is essential for shift-level energy accountability and supports the kind of operator-driven efficiency improvements that complement automated control strategies.

For facilities running SCADA platforms such as Rockwell FactoryTalk View SE or Wonderware InTouch, the 1764-24AWA connects via 1761-NET-AIC or 1761-NET-ENI Ethernet interface modules, enabling bidirectional data exchange with enterprise energy management systems. This connectivity allows production schedulers to align high-energy operations with off-peak tariff windows, reducing demand charges without disrupting output targets.

In high-throughput manufacturing environments, the 1764-24AWA contributes to energy optimization at multiple levels of the production hierarchy. At the machine level, its relay output architecture supports direct control of motor starters, solenoid valves, and heating elements — all of which are primary energy consumers in typical factory cells. By implementing time-based and condition-based control logic in RSLogix 500, engineers can program the 1764-24AWA to de-energize non-critical loads during scheduled breaks, shift transitions, and low-demand periods, reducing standby power consumption without requiring manual intervention.

At the line level, the 1764-24AWA supports production pacing strategies that reduce energy spikes associated with simultaneous equipment start-up. By staggering motor start sequences across a conveyor system — coordinating with upstream and downstream Allen-Bradley MicroLogix 1100 controllers via DH-485 peer-to-peer messaging — the 1764-24AWA helps flatten the facility's demand curve, which directly reduces peak demand charges on industrial electricity tariffs.

Thermal load management is another area where the 1764-24AWA delivers measurable value. By monitoring temperature sensor inputs from PT100 or thermocouple modules connected to the 1769-IR6 RTD input card, the controller can modulate heating and cooling cycles to maintain process temperatures within tight bands — preventing the energy waste associated with overshoot and undershoot in thermal processes. This is particularly relevant in food processing, pharmaceutical manufacturing, and plastics extrusion applications where thermal stability directly impacts both product quality and energy efficiency.

Predictive maintenance integration is supported through the 1764-24AWA's ability to log runtime hours, cycle counts, and fault events to internal data files accessible via RSLogix 500 Data Monitor. When combined with vibration sensors connected through 1769-IF4 analog input modules, the controller can flag early-stage bearing wear or motor degradation — enabling planned maintenance interventions that prevent unplanned downtime and the associated energy waste of emergency restart cycles.

NANKMOS maintains ready inventory of the 1764-24AWA with typical lead times of 1–3 business days for standard orders. All units are sourced from verified supply channels, individually tested prior to shipment, and covered by a 12-month warranty against manufacturing defects and functional failures. Our technical team is available to support application engineering, compatibility verification, and replacement planning for legacy MicroLogix 1500 installations.

Q1: What energy savings can I expect when deploying the 1764-24AWA with variable frequency drives? When the 1764-24AWA is used to coordinate Allen-Bradley PowerFlex 40 or PowerFlex 525 drives in pump, fan, or conveyor applications, energy savings of 20–40% are achievable compared to fixed-speed motor operation. The PLC enables demand-responsive speed control, eliminating the constant full-load operation that wastes energy during partial-load conditions.

Q2: Is the 1764-24AWA compatible with existing MicroLogix 1500 expansion modules and I/O? Yes. The 1764-24AWA is fully compatible with the MicroLogix 1500 expansion I/O family, including 1769 Compact I/O modules such as the 1769-IQ16, 1769-OW16, 1769-IF4, and 1769-IR6. It also supports communication with existing DH-485 networks and RS-232 peripherals, making it a direct replacement for aging base units without requiring rewiring or reprogramming of existing logic.

Q3: What does the pre-shipment testing process cover? Every 1764-24AWA unit shipped by NANKMOS undergoes a structured pre-shipment test that includes power-on verification, relay output continuity checks, communication port handshake testing (RS-232 and DH-485), and visual inspection for physical damage. This process ensures that the unit arrives ready for installation and reduces commissioning time on-site.

Q4: What warranty and supply support does NANKMOS provide for the 1764-24AWA? NANKMOS provides a 12-month warranty on all 1764-24AWA units covering manufacturing defects and functional failures under normal operating conditions. We maintain in-stock inventory for rapid fulfillment, with standard lead times of 1–3 business days.
