Product Description

Description

The 6ES5900-0AA12 is a SIMATIC S5 900-series CPU module with an integrated power supply. This unit is engineered to provide a 24V DC to 5V DC power conversion, specifically designed to support the operational requirements of the S5 PLC architecture. The 6ES5900-0AA12 features a built-in slot for an EPROM memory submodule, accommodating up to 8K bytes of memory to store control programs. Additionally, the module is equipped with an integrated operator and display panel, facilitating local diagnostics and status monitoring during system operation.

Features

  • Integrated CPU functionality for SIMATIC S5 systems
  • Built-in 24V DC to 5V DC power supply
  • Memory submodule slot for EPROM (up to 8K bytes)
  • Integrated operator and display panel
  • Compact design for modular control cabinet integration

Applications

  • Legacy SIMATIC S5 automation systems
  • Industrial process control and sequencing
  • Machine automation requiring dedicated EPROM memory
  • Remote monitoring of PLC status via integrated display

Installation Guidelines

  • Mounting: Install the 6ES5900-0AA12 module on a standard SIMATIC S5 rack. Ensure the backplane connectors are fully seated to maintain reliable communication and power distribution.
  • Powering: Verify that the primary power source is a stable 24V DC supply. Incorrect voltage levels may result in improper CPU operation or damage to the memory submodule.
  • Memory Submodule: When inserting or removing the EPROM submodule, ensure the power is switched off to prevent data corruption or electrical arcing at the contacts.
  • Environment: Keep the module away from high-vibration sources and ensure it operates within specified temperature limits for SIMATIC S5 components to prolong the life of the display and internal electronics.
