PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1756-L62 LOGIX5562 is a ControlLogix Logix5562 Processor - 4 MB Memory unit. This controller delivers 4 MB of user data and logic memory. It includes 478 KB of dedicated I/O memory. The module executes user logic with a program scan time of 0.08 milliseconds. Backplane current draw equals 1.2 A at 5 V DC and 14 mA at 24 V DC. It supports up to 128,000 digital I/O points and 4,000 analog I/O points across the system.
The processor mounts directly into any slot of a 1756 ControlLogix chassis. It provides an integrated RS-232 serial communication port for DF1, DH-485, and ASCII protocols. Multiple Logix5562 controllers can reside within a single chassis for distributed execution. The unit supports nonvolatile memory expansion using a 1784-CF128 CompactFlash card. Battery backup options include the 1756-BA1, 1756-BATM, or 1756-BA2 to preserve volatile RAM data. It is capable of Removal and Insertion Under Power within active 1756 ControlLogix chassis.
