What is the architectural role of the 6ES7223-1PH22-0XA0 within a SIMATIC S7-200 automation system?
The 6ES7223-1PH22-0XA0 is a compact digital I/O expansion module (EM 223) engineered to augment the I/O capacity of SIMATIC S7-200 controllers — specifically compatible with S7-22X CPUs — enabling distributed control of field-level devices via standardized binary signals.
What are the precise digital input characteristics supported by the 6ES7223-1PH22-0XA0 module?
This module incorporates 8 digital inputs with a nominal input voltage of 24 V DC. The inputs are configurable as sink/source, facilitating flexible sourcing/sinking polarity for discrete field sensors. Input “0” state is recognized from 0 – 5 V, and a valid “1” logic level ranges between 15 V DC and 30 V DC.
What are the output specifications and load capabilities of the 6ES7223-1PH22-0XA0?
The 6ES7223-1PH22-0XA0 provides 8 relay-based digital outputs, each capable of switching up to 2 A per channel. Relay outputs allow AC and DC load control with galvanic isolation, enabling the direct switching of actuators, lamps, and solenoids within the permissible voltage ranges.
How does the input signal propagation delay affect system timing with the 6ES7223-1PH22-0XA0?
For the 6ES7223-1PH22-0XA0, the maximum propagation delay from a “0” to “1” input transition at rated input voltage is approximately 4.5 ms for standard inputs — a critical metric when evaluating deterministic response times in discrete control applications.
Can the 6ES7223-1PH22-0XA0 be used as a standalone controller?
No — the 6ES7223-1PH22-0XA0 functions strictly as an I/O expansion module and requires an S7-200 base CPU (specifically S7-22X series) to orchestrate logic execution. It lacks standalone processing or programming capability.
What is the product lifecycle status of the 6ES7223-1PH22-0XA0?
According to Siemens industry cataloging, the 6ES7223-1PH22-0XA0 is categorized as a PM410 product cancellation, meaning it has been officially discontinued. Support may be limited to spare parts and service provisions via Siemens or authorized partners.
