SIEMENS 6ES7223-1BL32-0XB0 Used Working Digital I/O

Product Overview

The Siemens 6ES7223-1BL32-0XB0 (SM 1223) is a high-density Digital Input/Output Expansion Module for the SIMATIC S7-1200 PLC series. This module is designed to significantly increase the I/O capacity of a standard S7-1200 CPU, providing a balanced mix of 16 digital inputs and 16 digital outputs in a single compact housing. As a Used Working unit, it is an essential component for expanding machine automation capabilities, allowing for the integration of additional sensors, actuators, and solenoids while maintaining the high-speed performance and reliability of the Siemens TIA Portal ecosystem.

Key Features

• High-Density I/O Mix: Equipped with 16 Digital Inputs (24V DC) and 16 Digital Outputs (Transistor, 24V DC), offering 32 total points of control.
• Fast Response Time: Features a configurable input filter time (typically 0.2 to 12.8 ms), ensuring rapid detection of high-speed industrial signals.
• Transistor Outputs: Utilizes 24V DC sourcing transistor outputs, ideal for high-frequency switching and driving DC loads like solenoids and relays without mechanical wear.
• Seamless Integration: Connects directly to the right side of any S7-1200 CPU via the integrated slide-out bus connector.
• Advanced Diagnostics: Provides comprehensive status LEDs for each individual I/O point, as well as a "DIAG" LED for overall module health and communication status.
• Removable Terminal Blocks: Features front-facing, removable connectors that simplify wiring and allow for quick module replacement without disconnecting field cables.
• Galvanic Isolation: The internal logic is electrically isolated from the field power, protecting the central CPU from potential electrical noise or faults.

Item Condition (Used Working)

• Functional Status: Used Working. This expansion module has been professionally bench-tested with an S7-1214C CPU. All 16 inputs and 16 outputs have been verified for stable operation and signal accuracy.
• Physical State: Clean industrial condition. The front-panel status LEDs are bright and functional. The DIN rail mounting latch and bus connector are in excellent condition.
• Technical Integrity: No "I/O Fault" or "Hardware Error" flags were triggered during communication tests. The unit has been handled in a strict ESD-safe environment and cleared of dust.
• Note: Professional installation is recommended. Ensure the S7-1200 CPU's power budget (5V DC backplane current) is sufficient to support this additional module.
