Siemens 6ES7223-1PH32-0XB0 SIMATIC S7-1200 Digital I/O SM 1223
The Siemens 6ES7223-1PH32-0XB0 is a SIMATIC S7-1200 SM 1223 digital input/output module combining 8 digital inputs and 8 relay outputs in one compact module. The inputs are designed for 24 V DC signals and support sink/source wiring, while the relay outputs can switch both DC loads from 5 to 30 V and AC loads from 5 to 250 V, with a maximum switching current of 2 A. This combination provides flexible digital signal acquisition and load switching for machine automation, process equipment, control panels, and other S7-1200 applications.

Description
The Siemens SIMATIC S7-1200 SM 1223, DI 8×24 V DC, DQ 8x relay provides 8 digital inputs and 8 digital relay outputs for integrated monitoring and control of field devices. The digital inputs operate at a rated 24 V DC and support both sink and source connections, with a signal “0” recognized at up to 5 V DC and a signal “1” from 15 V DC. Standard input delays can be parameterized to 0.2, 0.4, 0.8, 1.6, 3.2, 6.4, or 12.8 ms, allowing the module to accommodate different switching and response requirements. The inputs are arranged in groups of two and support interrupt functionality, making the module suitable for sensors, switches, push buttons, limit switches, and other digital field devices.
The eight relay outputs provide flexible switching of AC and DC loads, with a rated switching current of 2 A and output voltage ranges of 5–30 V DC and 5–250 V AC. The outputs are relay-isolated and support resistive and inductive loads, with a maximum lamp load of 30 W for DC and 200 W for AC. Siemens specifies up to 10 million mechanical operating cycles and up to 100,000 operating cycles at rated load voltage, while diagnostic alarms and LED status indication provide convenient monitoring of input and output operation. The module also provides 1,500 V AC isolation from the backplane bus and is designed for reliable installation in SIMATIC S7-1200 control systems.
