Sercos III Bus Interface Description

Introduction

The TM5 Sercos III Bus Interface is the first element of the TM5 distributed I/O island.

The following figure shows the location of the TM5 Sercos III Bus Interface in a distributed I/O island:

Sercos III Bus Interface Overview

The TM5 Sercos III Bus Interface with built-in power distribution is composed of four different parts that can either be ordered together as a kit, or can be ordered separately as shown below:

Interface Power Distribution Module (IPDM)

The following table gives the available reference:

Reference	IPDM Description	Color
TM5SPS3	Bus interface 24 Vdc power supply	Gray

The distribution of the power by the IPDM consists of two dedicated electrical circuits:

Designation:	Description:
24 Vdc Main power	24 Vdc power that serves the electronics of the bus Interface Module and generates independent power for the TM5 power bus that serves the expansion modules.
24 Vdc I/O power segment	The 24 Vdc power that serves: the expansion modules, the sensors and actuators connected to the expansion modules, the external devices connected to the Common Distribution Modules (CDM).

Designation:

Description:

24 Vdc Main power

24 Vdc power that serves the electronics of the bus Interface Module and generates independent power for the TM5 power bus that serves the expansion modules.

24 Vdc I/O power segment
