SIEMENS 6ES7223-1BH30-0XB0 Used Working SIMATIC S7-1200 Digital I/O

Product Overview

The Siemens 6ES7223-1BH30-0XB0 (SM 1223) is a high-density digital expansion module designed for the SIMATIC S7-1200 PLC series. This versatile "Combo" module provides both inputs and outputs in a single compact housing, featuring 8 Digital Inputs (24V DC) and 8 Digital Outputs (24V DC Transistor). It is an ideal solution for expanding the I/O capacity of a CPU 1211C, 1212C, or 1214C when a balanced number of additional sensors and actuators are required. This Used Working unit provides Siemens' signature industrial reliability for machine control, interlocking, and signaling applications at a significant cost saving.

Key Features

• Integrated I/O Mix: Features 8 inputs and 8 outputs on one module, optimizing cabinet space and reducing the number of expansion cards needed.
• Transistor Outputs (Source): The 8 digital outputs are high-speed transistor types (Sourcing), suitable for high-frequency switching and interfacing with solenoids, relays, or PLC inputs.
• Standard 24V DC Operation: Both inputs and outputs operate on standard industrial 24V DC logic, ensuring compatibility with a wide range of industrial sensors and devices.
• Galvanic Isolation: Features electrical isolation between the internal bus and the load circuits to protect the CPU from field-side electrical noise or surges.
• Seamless TIA Portal Integration: Fully supported in all versions of Siemens TIA Portal for easy hardware configuration and diagnostics.
• Status Monitoring: Equipped with dedicated LED indicators for each input and output point, plus a module-level diagnostic LED for instant status verification.

Item Condition (Used - Working)

• Functional Status: Used - Working. This module has been professionally removed from a decommissioned control system. It has been bench-tested for communication and I/O point integrity.
• Physical State: Shows minor cosmetic marks and typical shelf wear consistent with industrial use. The plastic casing and DIN rail mounting clips are fully intact.
• Electrical Integrity: The backplane bus connector is in excellent condition with no bent pins. Terminal screw heads are clean and not stripped.
• Visual Reference: Please refer to the high-resolution images to verify the hardware (HW) version and firmware state; the unit pictured is the exact module you will receive.
