1. Product Overview | What This Product Does
This is a compact industrial PLC (Programmable Logic Controller) belonging to Rockwell MicroLogix 1400 series, acting as the core control brain for small & medium automated production equipment.
It collects real-time signals from on-site sensors, switches and analog measuring instruments via built-in I/O ports, executes pre-edited ladder logic control programs, and outputs commands to drive actuators, conveyors, valves and other execution components.
Equipped with Ethernet & RS‑232 multi communication interfaces, it supports data interaction with upper computer, HMI touch screen and other automation devices, realizing equipment automatic operation, data recording, remote monitoring and fault alarming, widely applied to decentralized small automation control scenarios.
2. Core Product Advantages & Key Features
