PRODUCT INFORMATION
Product Overview
Revision scope: These specifications describe 1747-L532/A (Series A). Check the corresponding technical data before specifying another hardware series.
The Allen-Bradley 1747-L532 is an SLC 500 processor module. It provides 16K words of user memory for program and data storage. This memory configuration includes 12K words for data or program and 4K words for data only. The module uses battery-backed RAM with optional Flash EPROM backup support. It supports up to 8,192 discrete I/O points across three local chassis.
The processor provides two onboard communication channels. Channel 0 supports RS-232 communication with DF1, ASCII, and DH-485 protocols. Channel 1 provides a DH-485 network communication interface. Typical bit execution speed is 0.44 microseconds per instruction. Program scan time averages 1 millisecond per K word of logic.
