not for liquid-cooled S120 Motor Modules
Overview
The TM150 Terminal Module is an interface module for evaluating up to 12 temperature sensors. It is linked to the
CU320-2 Control Unit via DRIVE-CLiQ and can be used with firmware version 4.5 or higher. With this Terminal
Module installed, it is possible, for example, to supply motor winding temperature measurements to the thermal motor
model of the control system, or to transfer temperature measurements taken at the motor windings, motor bearings,
etc. to a higher-level control system via the PROFIBUS or PROFINET interface of the CU320-2 Control Unit. The
TM150 Terminal Module covers a temperature range of -99°C to +250°C and can evaluate the following temperature
sensors:
·
PT100
·
PT1000
·
KTY84-130
·
PTC
·
Bimetallic NC contact
A 2-wire, 3-wire or 4-wire temperature evaluation circuit can be implemented. The TM150 Terminal Module can
evaluate up to 12 temperature sensors with a 2-wire evaluation circuit, and up to 6 temperature sensors with a 3-wire
or 4-wire evaluation circuit.
The possible options for connecting PT100 / PT1000 temperature sensors using 2x2 wires, 3 wires or 4 wires to the
temperature sensor inputs of the TM150 Terminal Modules are illustrated below.
Connection of PT100 / PT1000 temperature sensors using 2x2 wires, 3 wires and 4 wires to the TM150
The connecting cables to the temperature sensors must always be shielded. The cable shield must be connected to
ground potential at both ends with full 360° termination. Temperature sensor cables which are routed in parallel with
the motor cable must be twisted in pairs and separately shielded. The maximum permissible cable length to the
temperature sensors is 300 m.
These options are available for the following cabinet units:
