ABB 07AI91 GJR5251600R4202 Analog Input Unit

Overview: 07AI91 GJR5251600R4202 is a controller designed specifically for industrial applications launched by ABB, belonging to the AC 31 series. It features high reliability and performance, equipped with advanced control algorithms and flexible configuration options. Adopting a robust structure suitable for industrial environments, it can meet various industrial automation needs such as manufacturing, process control, and automation systems, enabling users to efficiently monitor and manage various processes.

Working Principle: This controller is based on the principle of Programmable Logic Controller (PLC). Users store the control program that expresses the requirements of the production process in the user program memory of the controller in advance. During operation, the Central Processing Unit (CPU) executes program instructions sequentially from the starting step according to the address indicated by the program counter, completing operations such as logical operations, sequence control, timing, counting, and arithmetic operations. It controls various machinery or production processes through digital input and output operations, and cyclically scans and executes the program to realize the control of industrial processes.
