Allen Bradley 1785-LT PLC-5/15 Processor

Product Introduction

The Allen Bradley 1785-LT PLC-5/15 Processor is an entry-level programmable logic controller designed for small to medium industrial automation applications. Part of the PLC-5 family, the 1785-LT offers reliable processing performance for managing modest I/O configurations and simple control logic in manufacturing and process systems.

The processor provides 6 K words of SRAM memory, allowing storage of control programs and data for small-scale automation tasks. It supports Data Highway (DH) and Remote I/O (RIO) communication channels, enabling connection with other PLC-5 modules and remote I/O racks for distributed control.

With a compact rack-mounted design, the 1785-LT is suitable for installation in standard PLC-5 racks and integrates seamlessly with Allen Bradley digital and analog I/O modules. Its design ensures stable operation under typical industrial conditions and supports small-scale automation systems where reliable and cost-effective control is required.

The processor draws 2.5 A at 5 VDC from the backplane, making it energy-efficient while providing sufficient power for processing and communication tasks.
