Product Details

Omron Programmable Logic Controller

The Omron CJ2M is a programmable logic controller(PLC) with pulse output and Ethernet networking computer interface device. It has 20K steps program capacity and 2,560 built-in I/O points. This PLC is for use with CJ2M Series. It has various attributes like faster function block calls and execution, faster interrupt handling and less overhead time that significantly improves its execution time. This module provides high-speed counters, interrupt inputs and pulse train/PWM outputs. It has added execution memory for function blocks that allow structured, object-oriented programming. It has a provision for adding a serial option module to RS-232C or RS-422A/485 communications ports. It supports different coding methods like instruction list, ladder logic, structured text and SFC.
