TM2ARI8HT

Introduction

This expansion module is an 8-point input module, temperature, with a terminal block.

For further hardware information, refer to TM2ARI8HT.

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.

NTC Probe

The temperature (Tm) varies in relation to the resistance (r) following the equation below:

G-SE-0005294.3.gif-high.gif

 

 

Where:

oTm = temperature measured by the probe, in Kelvin

or = physical value of the resistance in Ohm

oR = reference resistance in Ohm at temperature T

oT = reference temperature in Kelvin

oB = sensitivity of the NTC probe in Kelvin

R,T, and B must be greater or equal to 1.

If the resistance is selected as unit, the displayed value is equal to the probe resistance.

NOTE: 25 °C = 77 °F = 298.15 K
