Allen Bradley 1756-L62 ControlLogix5562 Logix5000 Processor Module

Product Overview

The Allen Bradley 1756-L62 functions as a core processing engine for the ControlLogix5562 system. This high-performance CPU manages complex control disciplines, including discrete, motion, process, and safety applications. It delivers rapid instruction execution and robust communication handling across the 1756 backplane. We supply this module as 100% Brand New, providing a factory-fresh solution for system expansions or critical hardware refreshes in existing ControlLogix architectures.

Technical Specifications

Engineering Advantages

• High-Speed Execution: The 1756-L62 boasts a program scan time of just 0.08 milliseconds. This ultra-low latency allows the controller to handle high-speed bottling, packaging, and synchronized motion tasks without compromising logic integrity.

• Massive I/O Scalability: This processor controls up to 128,000 total I/O points and 4,000 analog I/O points. This capacity enables engineers to manage entire plant-wide sub-systems from a single localized chassis, reducing hardware overhead.

• Flexible Serial Connectivity: The onboard RS-232 port supports multiple protocols including DF1, ASCII, and DH-485. This versatility simplifies integration with legacy serial devices, barcode scanners, and radio modems without requiring additional communication cards.

• Reliable Data Retention: The module utilizes a Compact Flash socket (1784-CF128) for nonvolatile storage. This ensures the controller retains the user program and tag data during long-term power outages, even if the primary battery fails.

FAQs

• Is the 1756-L62 currently in production or surplus?

  While the manufacturer has transitioned newer systems to the L7 and L8 series, we offer this 1756-L62 as 100% Brand New original stock. This allows you to maintain your current L6x architecture without the need for expensive firmware migrations or program rewrites.

• Does this processor require a battery for operation?

  The 1756-L62 requires a battery (such as the 1756-BA1) to maintain the user program in volatile RAM during power-down cycles. We recommend installing a fresh battery during the initial commissioning of the new module.

• Which software version do I need to program the 1756-L62?

  This module requires RSLogix 5000 or Studio 5000 Logix Designer. The specific version depends on the firmware revision loaded onto the processor. Always match your software version to the firmware revision for seamless online editing.

• Can I use the 1756-L62 in a redundant chassis configuration?

  Yes, the L62 supports redundancy. You must pair it with a 1756-RM redundancy module and ensure the firmware supports redundancy features to achieve high-availability synchronized control.
