Siemens 6ES7223-1BH32-0XB0 SIMATIC S7-1200 Digital I/O SM 1223
The Siemens 6ES7223-1BH32-0XB0 is a SIMATIC S7-1200 SM 1223 digital input/output module combining 8 digital inputs and 8 digital transistor outputs in a single compact module. Its inputs operate with 24 V DC signals and support sink/source wiring, while the transistor outputs can switch loads of up to 0.5 A per channel. This combination provides a practical solution for automation applications that require both field-signal monitoring and direct digital actuator control from one S7-1200 expansion module.

Description
The Siemens SIMATIC S7-1200 SM 1223, DI 8×24 V DC / DQ 8×24 V DC combines 8 digital inputs and 8 digital outputs for comprehensive discrete signal handling within one module. The digital inputs are designed for 24 V DC field signals and follow the IEC 61131 Type 1 input characteristic, with a signal “0” recognized at up to 5 V DC and a signal “1” beginning at 15 V DC. Typical input current at signal “1” is 4 mA per channel, and standard input delays can be parameterized from 0.2 ms to 12.8 ms. This allows the module to acquire signals from sensors, push buttons, switches, limit switches, and other digital field devices while accommodating different switching conditions.
The eight transistor outputs are rated at 24 V DC and 0.5 A per channel and are suitable for controlling valves, DC contactors, indicator lights, and other digital actuators. The outputs provide fast switching 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 internally limited to approximately L+ −48 V. The digital inputs are arranged in two groups of four, and the output section provides individual electrical separation from the backplane bus. Diagnostic alarms and LED status indication assist with monitoring both input and output operation. The module supports shielded cables up to 500 m and is designed for machine automation, production lines, conveyor systems, process equipment, and other S7-1200 applications requiring integrated digital input and output capability.
