Siemens 6ES5752-0AA22 Interface Module

This interface module connects SIMATIC S5 controllers to peripheral communication networks. It handles data exchange between the CPU and remote field stations. Therefore, this component enables distributed automation architectures for large facilities.

Physical Dimensions and Weight Specifications

The Siemens 6ES5752-0AA22 occupies one standard slot in the S5 rack. Its housing measures 233 mm in depth for backplane connectivity. The module weighs approximately 0.44 kg for straightforward handling. Consequently, technicians can install this unit without additional rack reinforcement.

Interface Types and Connection Layout

The Siemens 6ES5752-0AA22 provides one RS-485 port for fieldbus communication. A second 20-pin backplane connector links directly to the CPU bus. The front panel carries three LED indicators for network status monitoring. Hence, operators can diagnose communication errors at a quick glance.

Component Count and Communication Protocol

This interface module contains one main board with a dedicated protocol processor. The board holds 32 KB of buffer memory for message queuing. You will also find galvanic isolation circuits for the RS-485 port. An onboard oscillator generates the 18.432 MHz communication clock.

Energy Storage and Power Consumption

The Siemens 6ES5752-0AA22 draws 130 mA from the 5V backplane supply. A small electrolytic capacitor maintains buffer memory for 5 milliseconds. This short storage protects message data during brief power dips. The module does not require a backup battery for normal operation.

Network Performance and Message Handling

The module processes up to 200 messages per second at 187.5 kbps. It supports up to 32 stations on a single network segment. Users can configure this unit as either a master or a slave station. This flexibility suits both centralized and distributed control topologies.
