Field Bus Interface Description

Introduction

The TM5 field bus interface is the first element of the TM5 distributed I/O island.

The following figure shows the location of the TM5 field bus interface in a distributed I/O island:

Field Bus Interface Overview

The TM5 field 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:

Item	Description
1	Field bus interface bus base
2	Field bus interface module
3	Interface Power Distribution Module (IPDM)
4	Terminal block

Field Bus Interface Bus Base Description

The following figure shows the different parts of the field bus interface bus base:

1 Locking lever

2 DIN rail locking mechanism

3 DIN rail contact

4 Guides for assembly of the IPDM

5 Rotation axle for terminal block

6 TM5 bus power contacts

7 TM5 bus data contacts

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: othe expansion modules, othe sensors and actuators connected to the expansion modules, othe external devices connected to the Common Distribution Modules (CDM).
