PRODUCT INFORMATION
Product Overview
Revision scope: These specifications describe 1747-L524/B (Series B). Check the corresponding technical data before specifying another hardware series.
The Allen-Bradley 1747-L524 is an SLC 5/02 Controller for the SLC 500 system. It installs directly into slot 0 of an SLC 500 chassis. The unit provides 4K battery-backed RAM holding up to 4,000 instructions. It addresses up to 4,096 discrete inputs and 4,096 discrete outputs across connected chassis.
This controller supports up to 480 local analog points across three chassis. It can control up to 30 total I/O module slots. Program scan execution requires 4.8 milliseconds per 1K instructions. Backplane current draw equals 350 mA at 5V DC and 105 mA at 24V DC. RSLogix 500 software handles ladder logic programming and configuration.
