Allen-Bradley 1785-L80B | PLC5 Programmable Logic Controller

Product Overview

The 1785-L80B is an advanced PLC5 Programmable Logic Controller from Allen-Bradley, designed for industrial automation and process control. It integrates local, extended, and remote I/O modules, enabling seamless data exchange across diverse industrial systems.

This PLC5 processor supports up to 3072 input/output points, accommodating any combination of digital and analog signals. Its robust communication architecture features four configurable DH+/Remote I/O ports, one serial port compatible with RS-232, RS-422A, and RS-423, along with two dedicated programming terminals.

Equipped with battery-backed static RAM and optional EEPROM memory expansion, the 1785-L80B ensures program protection during power interruptions. With a maximum user memory of 100 Kilowords, this controller supports complex logic and large-scale industrial applications.

The front panel features multiple LED indicators for quick status checks. The BATT LED monitors battery health, PROC shows operational mode, FORCE signals I/O force status, and COMM indicates channel 0 communication. All four communication channels have dedicated status LEDs for streamlined diagnostics.
