SIRIUS 3RS14, 3RS15 temperature monitoring relays for IO-Link
Relays, digitally adjustable for up to 3 sensors

■
Overview
SIRIUS 3RS1441 digital temperature monitoring relay for up to 3 sensors
The 3RS14 temperature monitoring relays can be used to
measure temperatures in solid, liquid and gas media. The tem-
perature is calculated using a sensor in the medium, evaluated
by the device and monitored for overshooting or undershooting
a working range (window function). The devices can be param-
eterized to indicate the measured temperature in °C or °F.
The 3RS1441 evaluation unit can evaluate up to 3 resistance
sensors at the same time.

Benefits
•
Very simple operation without complicated menu selections
•
Space-saving with 45 mm width
•
Two- or three-point control can be parameterized quickly
•
All versions with removable terminals
•
All versions with screw or spring-type terminals
■
Application
The 3RS1441 temperature monitoring relays can be used almost
anywhere where several temperatures must be monitored at one
time for overshooting, undershooting or staying within a certain
range.
Monitoring of set temperature limits and output of alarm mes-
sages for:
•
Plant and environment protection
•
Temperature limits for process variables e.g. in the packaging
industry or electroplating
•
Controlling equipment and machines such as heating, climate
and ventilation systems, solar collectors, heat pumps or warm
water supplies
•
Motor, bearing and gear oil monitoring
•
Monitoring of coolants
■
