Allen Bradley 1785-LT3 PLC-5/12 Processor

Product Introduction

The Allen Bradley 1785-LT3 PLC-5/12 Processor is an entry- to mid-level programmable logic controller designed for small-scale industrial automation applications. Part of the PLC-5 family, this processor offers reliable control for simple to moderately complex systems, with support for both digital and analog I/O via integrated network channels.

The PLC-5/12 features 6 K words of SRAM memory, sufficient for compact control programs and small data tables. It includes one Data Highway Plus (DH+) channel and one Remote I/O (RIO) channel, allowing communication with remote racks, I/O modules, and other PLC-5 devices for distributed control applications.

With a compact form factor designed for PLC-5 racks, the processor draws 2.5 A at 5 VDC from the backplane, ensuring stable and energy-efficient operation. It is widely used in small manufacturing lines, machine control, and process automation tasks where reliable entry-level PLC-5 control is needed.
