The Siemens module you mentioned, 6ES7226-6BA32-0XB0, is part of the Siemens S7-1200 series programmable logic controllers (PLCs). It is specifically a relay output expansion module designed to work with the S7-1200 PLC system.

Here's some information about the module:

- Model number: 6ES7226-6BA32-0XB0

- Manufacturer: Siemens

- Series: S7-1200

- Function: Relay Output Expansion Module

Key Features:

- The module provides additional relay outputs to expand the output capacity of the S7-1200 PLC.

- It has 16 relay outputs with 2 amps per output.

- The relay outputs are capable of switching DC loads up to 30 volts and AC loads up to 250 volts.

- The module can be easily attached to the main unit of the S7-1200 PLC system.

- It supports hot swapping, which means you can add or remove the module while the system is powered on without affecting the operation of other modules.

This module is commonly used in industrial automation applications where there is a need for additional relay outputs to control various devices such as solenoid valves, motors, lights, etc.
