Product Description

The 6ES5243-1BA11 module is a legacy SIMATIC S5 243 I/O expansion unit for SIEMENS PLC systems, featuring 8 digital inputs and 8 relay outputs. Designed for direct local expansion, it supports up to 4 additional modules via a backplane bus. Operating at 24V DC (±10%) within 0–60°C, it integrates an RS-485 serial interface for basic communication. Widely used in industrial automation, manufacturing, and machinery control, this module offers high reliability and backward compatibility with S5 systems. However, it lacks support for modern protocols like PROFINET or Ethernet/IP. The module does not include an internal battery, display, or sensor interfaces, making screen size and detection distance specifications irrelevant. Its compact design suits space-constrained installations but requires legacy programming tools for configuration.
