ALSTOM+AL132 AL132A STO0982E01 seems to be a combination of modules that might be used in an ALSTOM industrial automation or control system.

Product Name:

Individual modules :ALSTOM AL132, AL132A and STO0982E01.

Product Description:

Industrial control systems with scalable capabilities: The AL132 module may be the core of the control system, handling the control logic and interfaces with other devices. The AL132A module can be used as an expansion board, providing additional features such as:

Increase input/output (I/O) capacity to connect more sensors and actuators
An additional communication port for connecting to other systems on the network
Dedicated processing capabilities for specific control tasks
Redundant control systems: In safety-critical applications, it is possible that the AL132 and AL132A modules are identical and act as redundant control systems. This means they run in parallel, performing the same control tasks, and if one module fails, the other can take over to ensure uninterrupted operation.

Parameters and Specifications:
Redundant control system:

Each module (AL132 and AL132A) has the same processing power, memory capacity, and I/O capacity.
The redundancy management function automatically switches to the backup module when the primary module fails.
