Siemens 6ES7223-1BL32-0XB0 SIMATIC S7-1200 Digital I/O SM 1223
The Siemens 6ES7223-1BL32-0XB0 is a SIMATIC S7-1200 SM 1223 digital input/output module with 16 digital inputs and 16 digital transistor outputs, providing 32 digital channels in one expansion module. The inputs operate with 24 V DC signals and support sink/source wiring, while the transistor outputs provide up to 0.5 A per channel for controlling digital actuators. Its high channel density makes it suitable for larger machines, production systems, and automation installations where a substantial number of digital signals must be monitored and controlled from a single PLC module.

Description
The Siemens SIMATIC S7-1200 SM 1223, DI 16×24 V DC / DQ 16×24 V DC combines 16 digital inputs and 16 digital outputs in one module, providing a total of 32 discrete channels for industrial automation systems. The digital inputs are rated for 24 V DC operation and use the IEC 61131 Type 1 input characteristic. A signal “0” is recognized at up to 5 V DC, while a signal “1” is recognized from 15 V DC at the specified input current. The inputs typically consume 4 mA per channel at signal “1”, and their standard input delay can be parameterized from 0.2 ms through 12.8 ms, providing flexibility for different sensor and switching requirements.
The 16 digital transistor outputs provide 24 V DC switching at up to 0.5 A per channel, making them suitable for valves, contactors, indicator lamps, and other low-voltage DC actuators. The outputs support fast response, with a maximum delay of 50 µs from 0 to 1 and 200 µs from 1 to 0 for resistive loads, while inductive shutdown voltage is limited to approximately L+ −48 V. The module supports shielded field cables up to 500 m and unshielded cables up to 300 m, while diagnostic alarms and LED indicators provide convenient monitoring of input and output status. Its 70 mm wide housing provides the additional terminal capacity required for 32 digital channels, making the module suitable for large machine-control systems, production lines, conveyor equipment, packaging machinery, process equipment, and high-density S7-1200 digital I/O applications.
