Siemens 6ES5310-3AB11 IM 310 Interface Module

Product Overview

The Siemens 6ES5310-3AB11 is an IM 310 interface module for the expansion-unit side of a SIMATIC S5 control system. It provides the connection between an expansion unit and the central controller in a distributed configuration, working with an IM 301 module on the controller side. This arrangement allows S5 I/O equipment to be located away from the central controller while remaining part of the same control system. Siemens documents an IM 301/IM 310 connection length of 1 to 200 m using the 6ES5 721 cable family. The 6ES5310-3AB11 serves this defined interface role; it is not an I/O channel module. 

Technical Specifications

Key Features & Model Benefits

- Distributed S5 connection: Links an expansion unit to the central controller through an IM 301/IM 310 interface pair.
- Up to 200 m link length: Supports the distance specified by Siemens for this interface arrangement.
- Defined expansion-unit role: Identified in Siemens documentation as the IM 310 module on the expansion-unit side.
- S5 I/O integration: The documented interface pair carries supported digital and analog I/O modules in the expansion unit. 

Frequently Asked Questions

Q: What does 6ES5310-3AB11 do in a SIMATIC S5 system?
A: It is the IM 310 interface module on the expansion-unit side of a distributed controller-to-expansion connection.
Q: What connection distance is specified for 6ES5310-3AB11?
A: Siemens specifies 1 to 200 m for the documented IM 301/IM 310 arrangement using the 6ES5 721 cable family.
Q: Which central-controller interface pairs with 6ES5310-3AB11?
A: The Siemens system manual lists IM 301-3 and IM 301-5, depending on the expansion-unit configuration.
Q: Is 6ES5310-3AB11 a digital or analog I/O module?
A: No. It is an interface module that connects the expansion unit to the central-controller side of the S5 system.
