Channels
Temperature
Temperature input channels monitor RTD or thermocouple temperature sensors inputs for the most
common ranges. You can also configure severity alarms that can send an email, a syslog message,
and/or an SNMP trap when an alarm is triggered or cleared; See
Alarm Settings on page 271 for
more information about the alarms.
RTD ranges are:
z Pt100 a=385 -50 to 150C z Pt100 a=392 -50 to 150C z Pt1000 a=385 -40 to 160C
z Pt100 a=385 0 to 100C z Pt100 a=392 0 to 100C z NiFe604 a=518 -80 to 100C
z Pt100 a=385 0 to 200C z Pt100 a=392 0 to 200C z NiFe604 a=518 0 to 100C
z Pt100 a=385 0 to 400C z Pt100 a=392 0 to 400C
z Pt100 a=385 -200 to 200C z Pt100 a=392 -200 to 200C
Note:
IEC RTD 100 ohms.=0.00385
JIS RTD 100 ohms.=0.00392
Thermocouple ranges are:
z B 500 to 1800C z K 0 to 1370C z T -100 to 400C
z E 0 to 1000C z R 500 to 1750C
z J 0 to 760C z S 500 to 1750C
In the following example, a Temperature I/O IOLAN is used to monitor industrial freezer temperature
sensors, with an alarm set to send a syslog message if the temperature rises above 31

C.
