TM3TI4 / TM3TI4G

Introduction

The TM3TI4 (screw terminal block) / TM3TI4G (spring terminal block) expansion module feature 4 analog input channels with 16-bit resolution.

The channel input types are:

0...10 V
-10...+10 V
0...20 mA
4...20 mA
K thermocouple
J thermocouple
R thermocouple
S thermocouple
B thermocouple
E thermocouple
T thermocouple
N thermocouple
C thermocouple
PT100
PT1000
NI100
NI1000

For information on the diagnostic codes produced by each input type, refer to Analog I/0 Modules Diagnostics.

For further hardware information, refer to TM3TI4 / TM3TI4G.

NOTE:

If you have physically wired the analog channel for a voltage signal and you configure the channel for a current signal in EcoStruxure Machine Expert, you may damage the analog circuit.

NOTICE
	INOPERABLE EQUIPMENT Verify that the physical wiring of the analog circuit is compatible with the software configuration for the analog channel. Failure to follow these instructions can result in equipment damage.

Configuring the Module

For each input, you can define:

Parameter		Value	Default Value	Description
Type		Not used 0 - 10 V -10 - +10 V 0 - 20 mA 4 - 20 mA K Thermocouple J Thermocouple R Thermocouple S Thermocouple B Thermocouple E Thermocouple T Thermocouple N Thermocouple C Thermocouple PT100 PT1000 NI100 NI1000	Not used	Choose the mode of the channel.
Scope		Customized Celsius (0.1°C) Fahrenheit (0.1°F) Fahrenheit (0.2°F)*	Customized	The range of values for a channel. * Only for B and C thermocouples.
Min.	0 - 10 V	-32768...32767	0	Specifies the lower measurement limit.
	-10 - +10 V		-10000
	0 - 20 mA		0
	4 - 20 mA		4000
	Temperature	See the table below
Max.	0 - 10 V	-32768...32767	10000	Specifies the upper measurement limit.
	-10 - +10 V		10000
	0 - 20 mA		20000
	4 - 20 mA		20000
	Temperature	See the table below
Input Filter		0...1000	0	Specifies the first order filter time constant (0...10 s) in increments of 10 ms.
Sampling		10ms/Channel 100ms/Channel	100ms/Channel	Specifies the sampling period of the channel. If an input filter is active, sampling is set internally to 10 ms.
Status Enabled		Yes No	Yes	Enables the diagnostic byte of each channel. If the status is disabled (value = No), the status bytes `IBStatusIWx` do not contain relevant information.
