Allen-Bradley 1747-L30D SLC 500 Processor Module

The Allen-Bradley 1747-L30D SLC 500 Processor Module is a 16 KB user memory, 30-point SLC 500 CPU (SLC 5/03) designed to execute control logic and manage I/O in PLC systems. It provides 18 digital inputs and 12 DC outputs at 24 VDC, features a DH-485 network port for serial communication, and is RSLogix 500 compatible for programming. Panel-mount with battery-backed RAM memory retention, it supports SLC 500 Expansion Chassis and operates from 0°C to 60°C in industrial environments. Common replacements include 1747-L30E, 1747-L40D, and 1747-L511, and it is used by system integrators for replacements and retrofit projects in packaging, conveyors, and assembly equipment across manufacturing lines where PLC-based control and real-time monitoring are required.
