Overview
SIRIUS 3RS14, 3RS15 temperature monitoring relay
The temperature monitoring relays for IO-Link are used to
measure temperatures in solid, liquid and gas media.
The temperature is calculated using a sensor in the medium,
evaluated by the device and monitored up to two limit values
for overshooting or undershooting a working range
(window function).
In addition to warnings and disconnection in case of tempera-
ture deviations, the devices can also be used as a temperature
controller (one-point, two-point or three-point control).
The devices differ from one another in terms of the type and
number of connectable temperature sensors.

3RS14: Connection for resistance sensor
•
3RS15: Connection for thermocouples

Notes:
Devices required for the communication via IO-Link:
•
Any controller that supports the IO-Link (e.g. ET 200SP
with CPU or S7-1200);
see Catalog ST 70 "Products for
Totally Integrated Automation"
.
•
IO-Link master (e.g. CM 4xIO-Link for SIMATIC ET 200SP
or SM 1278 for S7-1200);
see page 2/108 and page 2/109
.
Each monitoring relay requires an IO-Link channel.

Notes on safety
In order to protect plants, systems, machines and networks
against cyber threats, it is necessary to implement – and contin-
uously maintain – a holistic, state-of-the-art industrial security
concept. Siemens products and solutions represent only one
component of such a concept.
