Product Details

1336S-EN4 42336-224-51 Product Description

The Allen-Bradley 1336S-EN4 42336-224-51 is a high-performance AC variable frequency drive from the 1336 PLUS Series, engineered for seamless integration into industrial data networks and smart factory automation architectures. Designed to bridge field-level motor control with upper-level supervisory systems, this drive supports DH+ (Data Highway Plus) and RS-232 communication protocols, enabling real-time data exchange across PLC controllers, SCADA platforms, HMI terminals, and distributed control systems. Whether deployed in discrete manufacturing, process automation, or energy management applications, the 1336S-EN4 42336-224-51 delivers reliable motor speed regulation while maintaining full network visibility across the automation hierarchy.

In a modern smart factory, the Allen-Bradley 1336S-EN4 42336-224-51 functions as a critical node in the industrial data chain, connecting motor-driven field equipment to the plant-wide control and monitoring infrastructure. The data flow begins at the sensor and actuator level, where process variables such as motor speed, current draw, output frequency, and fault status are continuously captured by the drive's internal diagnostics engine. These parameters are transmitted in real time over the DH+ network to upstream Allen-Bradley PLC-5 or SLC 500 controllers, which process the data and issue closed-loop control commands back to the drive.

Within a ControlLogix-based architecture, the 1336S-EN4 42336-224-51 integrates alongside Allen-Bradley 1756-DHRIO communication bridge modules, which translate DH+ signals into ControlNet or EtherNet/IP frames for transmission to higher-level systems. This enables the drive's operational data to reach Rockwell Automation FactoryTalk View SCADA platforms and PanelView HMI terminals without protocol conversion gaps. Operators can monitor drive status, adjust speed references, and acknowledge fault conditions directly from the HMI screen, eliminating the need for manual intervention at the drive panel.

For remote I/O expansion, the 1336S-EN4 42336-224-51 works in conjunction with Allen-Bradley 1771 Remote I/O adapter modules, extending the control network to distributed field devices across large production floors. In energy-intensive applications, the drive's network-linked speed control pairs effectively with Allen-Bradley PowerFlex 700 drives deployed on parallel motor circuits, allowing coordinated multi-drive management from a single SCADA node. Process sensors connected via Allen-Bradley 1734 POINT I/O modules feed real-time analog signals into the control loop, enabling the drive to respond dynamically to changing process conditions.

At the edge layer, Allen-Bradley 1783 Stratix industrial Ethernet switches provide the backbone switching infrastructure that connects DH+ gateway nodes to the plant Ethernet segment, ensuring low-latency data delivery to MES and ERP systems. For facilities integrating legacy DH+ equipment with modern EtherNet/IP networks, the Allen-Bradley 1761-NET-AIC Advanced Interface Converter serves as the protocol bridge, maintaining backward compatibility while enabling forward connectivity. Data visualization dashboards built on FactoryTalk Historian aggregate drive performance trends, energy consumption metrics, and fault event logs, supporting predictive maintenance workflows and production KPI reporting.

Many industrial facilities operating mixed-generation automation equipment face persistent challenges: protocol fragmentation between legacy DH+ devices and modern EtherNet/IP systems, data silos that prevent unified production visibility, and limited remote diagnostic capability for distributed drive assets. The Allen-Bradley 1336S-EN4 42336-224-51 directly addresses these pain points through its native DH+ communication interface, which integrates without additional protocol converters into existing Allen-Bradley PLC-5 and SLC 500 control networks.

For sites struggling with alarm traceability, the drive's network-accessible fault register allows SCADA systems to log timestamped fault events — overcurrent trips, undervoltage conditions, communication timeouts — and route alarm notifications to operator workstations in real time. This eliminates the manual fault-log review process and accelerates mean time to repair (MTTR). Remote diagnostic access via the DH+ network allows maintenance engineers to read drive parameters, reset faults, and adjust acceleration/deceleration ramps from the control room, reducing unplanned downtime without requiring physical access to the drive enclosure.

Production line transparency is further enhanced by integrating the 1336S-EN4 42336-224-51 into FactoryTalk View SE SCADA environments, where motor speed trends, energy consumption data, and drive health indicators are displayed on unified operator dashboards. As production demands scale, the DH+ network architecture supports the addition of further 1336 PLUS drives and remote I/O nodes without requiring infrastructure redesign, providing a cost-effective path for system expansion. All units are pre-tested prior to shipment and covered by a 12-Month Warranty, ensuring operational confidence from day one of deployment.

Q1: What communication protocols does the Allen-Bradley 1336S-EN4 42336-224-51 support, and which PLC platforms are compatible? The 1336S-EN4 42336-224-51 supports DH+ (Data Highway Plus) and RS-232 protocols via its EN4 communication adapter. It is natively compatible with Allen-Bradley PLC-5, SLC 500, and ControlLogix platforms equipped with 1756-DHRIO or equivalent DH+ interface modules. This enables direct parameter exchange, speed reference commands, and fault status reporting without additional protocol gateways.

Q2: How does this drive perform in terms of network latency and communication stability in SCADA-connected environments? The DH+ network used by the 1336S-EN4 42336-224-51 operates at up to 57.6 Kbps with deterministic token-passing communication, providing consistent, low-jitter data delivery suitable for real-time SCADA monitoring and closed-loop control. Network stability is maintained through the DH+ token-ring architecture, which prevents data collisions and ensures reliable message delivery even in electrically noisy industrial environments.

Q3: Can the 1336S-EN4 42336-224-51 be integrated into a modern EtherNet/IP or ControlNet architecture alongside newer Allen-Bradley drives? Yes. By deploying an Allen-Bradley 1756-DHRIO bridge module within a ControlLogix chassis, the 1336S-EN4 42336-224-51 can be integrated into EtherNet/IP or ControlNet-based control architectures. This allows the drive to coexist with newer Allen-Bradley PowerFlex 525 or PowerFlex 755 drives on a unified network, enabling coordinated multi-drive management from a single FactoryTalk SCADA or Studio 5000 Logix Designer environment.

Q4: What warranty and pre-shipment testing does the 1336S-EN4 42336-224-51 carry? Every Allen-Bradley 1336S-EN4 42336-224-51 unit supplied by NANKMOS undergoes functional testing prior to shipment, verifying communication interface integrity, power stage operation, and parameter configuration. The unit is covered by a 12-Month Warranty from the date of delivery, covering manufacturing defects and component failures under normal operating conditions. In-stock units are available for immediate dispatch with full documentation support.
