Allen-Bradley 1747-L532 SLC 5/03 Processor, 16K Memory, DH-485 + RS-232
Allen-Bradley 1747-L532 is an SLC 500 slc 5/03 occupying a single slot of a 1746 I/O chassis, with 16K words of user memory and dh-485 + rs-232.
Overview
The processor mounts in a single slot of a 1746 I/O chassis and is powered from the chassis power supply (1746-P1 to 1746-P7). It addresses up to 4096 discrete inputs and 4096 discrete outputs across up to three local chassis (30 slots). User memory is 16K words with battery-backed RAM and a user-replaceable 1747-BA battery. Communication is DH-485 + RS-232 (DF1); scan times are 1 ms/K per Kword for programs and 0.225 ms for I/O, with backplane current draw of 500 mA at 5V DC / 175 mA at 24V DC. A 1747-M13 Flash EPROM module provides non-volatile program backup, and the processor draws 2.9 W total.
