Siemens 6ES7223-1BH32-0BX0

Siemens 6ES7223-1BL32-0XB0 Digital I/O Module

The Siemens 6ES7223-1BL32-0XB0 is a high-performance digital input/output module designed for the SIMATIC S7-1200 automation system. This SM 1223 module includes 16 digital outputs, supporting 24 V DC sink/source inputs and transistor-based outputs rated at 0.5 A. It enables seamless control and monitoring of digital signals in industrial automation systems, offering efficient integration with PLC operations. Backed by Siemens' engineering excellence and available with a 2-year warranty and free shipping from MRO Electric and Supply, this module is dependable for industrial control applications requiring durability and flexibility.

Electrical Performance and Input Capabilities

This module operates within a rated supply voltage of 24 V DC, with a permissible range from 20.4 V to 28.8 V, ensuring stable operation even with minor voltage fluctuations. Each of the 16 digital inputs adheres to IEC 61131 type 1 standards, making it suitable for precise and reliable signal detection. The inputs are divided into groups of two and can handle signal "0" at 5 V DC (1 mA) and signal "1" at 15 V DC (2.5 mA), with a typical current draw of 4 mA. The module supports configurable input delays ranging from 0.2 ms to 12.8 ms, allowing tuning based on specific timing needs. Inputs can also function effectively across extended cable lengths—up to 500 meters shielded or 300 meters unshielded.

Output Performance and Control Flexibility

The 16 transistor-based digital outputs deliver fast switching performance and are divided into groups, each supporting a current load of up to 0.5 A. With a rated output voltage of 24 V DC, they maintain low residual voltage in the "0" state (0.1 V max) and a strong high signal in the "1" state (20 V DC minimum). Designed without internal short-circuit protection, users must implement external protection to maintain output integrity. This module also supports inductive shutdown with a voltage limit of L+ (-48 V), helping to safeguard connected components. The fast switching times—maximum 50 µs for ON and 200 µs for OFF—make it ideal for applications requiring quick response rates.

Diagnostics, Indicators, and Environmental Durability

Siemens has built comprehensive diagnostics into the 6ES7223-1BL32-0XB0. The module offers LED indicators for the status of both inputs and outputs, as well as maintenance and diagnostic alerts to ensure operators can monitor system health in real time. It features group-based potential separation for inputs and outputs and can withstand operation in a wide temperature range from -20 °C to +60 °C. The IP20 protection rating makes it ideal for control cabinet installations, and with approvals from CE, CSA, UL, cULus, and more, it is globally accepted for industrial use. Its sturdy plastic enclosure and compact form factor (70 mm wide, 100 mm high, 75 mm deep) support easy integration into existing control systems.
