The Siemens 6ES5314-3UA11 connects remote I/O racks to SIMATIC S5 central controllers. This module belongs to the IM314 interface family. You will find this board in distributed automation systems across factories. It links main racks with expansion units up to 100 meters away.

Manufacturer: Siemens
Series: SIMATIC S5
Category: Interface Module (IM314 Remote I/O)

Physical Dimensions and Weight

The Siemens 6ES5314-3UA11 measures 12.0 inches in length. Its width reaches 1.6 inches for single-slot occupancy. The board thickness sits at 5.5 inches including components. This standard form factor fits into any S5 series rack. The total weight comes to approximately 0.4 kilograms.

Technical Specifications and Communication Capabilities

This interface module uses a dedicated 20mA current loop for data transfer. It supports baud rates up to 1.5 Mbits per second. The module connects up to four remote racks to one central unit. It handles up to 256 digital I/O points per remote rack. Furthermore, the transmission distance reaches 100 meters maximum.

Data Buffering and Energy Storage

The Siemens 6ES5314-3UA11 includes a 2KB FIFO buffer for data queuing. This buffer prevents data loss during peak communication periods. The module uses capacitor arrays for transient protection on the line. Four capacitors store 100 microfarads each for energy buffering. Therefore, electrical noise does not corrupt your I/O data.

Interface and Connectivity

This interface module provides two 15-pin D-sub connectors for cabling. One connector handles transmit and receive signals. The second connector provides loop power for remote racks. Five LED indicators show power, data activity, and error status. A 4-position DIP switch sets the station address and baud rate.

Component Layout and Processing Architecture

The Siemens 6ES5314-3UA11 contains 110 discrete components on a four-layer PCB. Key parts include a communication controller chip and eight optocouplers. The architecture provides galvanic isolation between central and remote racks. This isolation withstands 1,500V AC for safety. Consequently, ground loops do not affect your control system.

Integration and Compatibility

Use the Siemens 6ES5314-3UA11 with any S5 central CPU module. It works alongside 6ES5314-3UA21 or 6ES5314-3UA31 interface modules. This interface supports all standard S5 remote rack configurations.
