Siemens6ES5300-5CA11SIMATIC S5 IM 300 Interface Module, Centralised Expansion Unit to Central Controller, Without Power Supply

Product Description

What this part is

The Siemens 6ES5300-5CA11 is the SIMATIC S5 IM 300 interface module, used in centralised configurations to connect an expansion unit (EU) to a central controller (CC), or to an expansion unit in compact version. It is the EU-side interface without its own power supply, so the expansion rack draws from the configuration rather than a local supply. It is documented for the S5-135U and S5-155U subsystems. German-manufactured new old stock.

Published specifications

Series: SIMATIC S5 IM 300 interface modules. Base Number: 6ES5300. Board Size: approximately 200 x 250 x 30 mm (8 x 10 x 1 in). Weight: approximately 0.361 kg (0.80 lb). Power Supply: none on board.

What these specs mean in practice

This is the module that lets an S5 rack grow beyond the slots available in the central controller while keeping the I/O local and centrally configured, as opposed to a distributed setup running over a serial link. IM 300 senders and receivers pair as a matched set within the IM300 family.

Quantity and configuration

Unit Quantity: 1 Pc. One interface module.

Interchange guidance

SIMATIC S5 is long discontinued, so new old stock and tested-exchange boards are the normal route for keeping S5 plant running. The 6ES5300-3AB11 is a separate IM300 variant.
