The Siemens 6ES7 235-0KD22-0XA0 Analog I/O Module is a specialized analog I/O expansion module designed for the SIMATIC S7-200 PLC platform. It operates exclusively with the S7-22X series of CPUs, providing an integrated solution for applications requiring both signal acquisition and control output. This dedicated compatibility ensures reliable performance and straightforward integration within its intended system architecture.

A core functional feature of the Analog I/O Module Siemens 6ES7235-0KD22-0XA0 is its combination of four analog inputs and one analog output. The inputs are configured to handle DC voltage signals in the range of +/-10V, while the single output channel provides the same +/-10V DC capability. The module utilizes a 12-bit converter for both input and output operations, offering a balanced level of precision for basic to intermediate control tasks.

The design of the 6ES7235-0KD22-0XA0 Siemens EM 235 Analog I/O Module emphasizes compact integration, allowing users to add analog functionality without consuming excessive panel space. It is important to note that this product has reached its end of production life and is designated as a non-returnable spare part. This status indicates that the ANALOG I/O EM 235 Siemens 6ES7235-0KD22-0XA0 is intended for maintaining existing installations rather than new system designs.

With its specific voltage range and integrated I/O structure, the SIMATIC S7-200 Siemens 6ES7 235-0KD22-0XA0 was well-suited for applications such as driving servo controllers or interfacing with process variables where bipolar voltage signals are standard. Its compact physical dimensions and light weight facilitated flexible installation in control cabinets, supporting the lifecycle needs of legacy S7-200 automation systems.
