Allen Bradley 1785-LT2 PLC-5/25 Processor

Product Introduction

The Allen Bradley 1785-LT2 PLC-5/25 Processor is a mid-range programmable logic controller designed for small to medium industrial automation systems. As part of the PLC-5 family, it offers enhanced processing capability compared to entry-level models, supporting larger I/O counts, analog I/O, and advanced communication options for distributed control systems.

Equipped with 13 K words of SRAM memory, the 1785-LT2 provides sufficient program and data storage for moderately complex automation tasks. The processor can manage up to 1024 total I/O points, including 1024 analog I/O, making it suitable for applications that require both digital and analog control. Its DH+ (Data Highway Plus) channel and Remote I/O channel enable integration with remote racks, operator interfaces, and networked PLC-5 devices.

Designed for installation in standard PLC-5 racks, the processor draws 2.5 A at 5 VDC from the backplane, ensuring energy-efficient operation. The 1785-LT2 is widely used in industrial plants, manufacturing lines, and process control systems where reliable, distributed control is necessary.
