产品介绍
The Allen-Bradley 1747-L20C I/O Processor 单位 is a fixed hardware style controller within the SLC 500 family, designed for small to medium-scale industrial automation tasks that require reliable control, integrated I/O, and straightforward communication capabilities. This controller combines processing, memory, power supply, and I/O functions into a single compact 件, reducing system complexity and panel space requirements.
Equipped with 1K words / user memory, the 1747-L20C is well suited for discrete control, sequencing, and basic data handling applications. It supports DH-485 communication, enabling peer-to-peer data exchange, programming access, and networked control within SLC 500 systems. The built-in 24V DC digital inputs allow direct connection / field devices without the need for additional I/O modules.
Designed for continuous industrial operation, the 1747-L20C /fers stable performance, predictable execution, and compatibility with legacy SLC 500 programming environments, making it an ideal choice for system upgrades, replacements, or dedicated control stations.
