SIEMENS 6ES7216-2AD23-0XB0 Used Working PLC CPU

Product Overview

The Siemens 6ES7216-2AD23-0XB0 (CPU 226) is the most powerful Central Processing Unit in the SIMATIC S7-200 micro-PLC range. Designed for complex automation tasks that require higher I/O counts and expanded memory, this controller is a staple in high-speed industrial machinery and process control. As a Used Working unit, it provides a reliable, cost-effective solution for maintaining legacy systems where high-density integrated I/O and dual communication ports are required.

Key Features

• High-Density Integrated I/O: Features 24 Digital Inputs (24V DC) and 16 Digital Outputs (24V DC Transistor), allowing for extensive control without additional expansion modules.
• Dual RS-485 Ports: Equipped with two independent PPI/Freeport communication ports, enabling simultaneous connection to an HMI, a programming PC, or other field devices.
• Expanded Memory: Offers 8 KB of user program memory and 5 KB of data memory, suitable for sophisticated logic and data logging.
• High-Speed Counters: Includes 6 integrated high-speed counters (up to 30 kHz), ideal for positioning and frequency measurement tasks.
• Pulse Outputs: Features 2 high-speed pulse outputs (up to 20 kHz) for controlling stepper motors or servo drives via Pulse Width Modulation (PWM) or Pulse Train Output (PTO).
• Modular Expandability: While powerful on its own, it supports the addition of up to 7 expansion modules for further I/O or specialized functions.
• Real-Time Clock: Built-in hardware clock for time-stamped events and scheduled automation cycles.

Item Condition (Used Working)

• Functional Status: Used Working. This CPU has been professionally bench-tested. Both communication ports (Port 0 and Port 1) have been verified for stable data transfer. All 24 inputs and 16 outputs have been functionally checked.
• Physical State: Clean industrial condition. The terminal covers are present, and the DIN rail mounting clips are secure. The plastic housing shows no signs of significant wear or heat stress.
• Technical Integrity: The internal EEPROM has been cleared of previous user programs. The unit passes all internal "System Block" diagnostics upon power-up. Handled in a strict ESD-safe environment.
• Note: Professional installation is recommended. This model uses Transistor outputs (DC); ensure your load requirements match the DC switching specifications.
