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 temperature deviations, the devices can also be used as a temperature controller (one-step, two-step or three-step 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 thermoelements

Temperature monitoring relays for IO-Link

Notes:

Devices required for the communication via IO-Link:

• Any controller that supports IO-Link (e.g. ET 200SP with CPU or S7-1200)
• IO-Link master (e.g. CM 4xIO-Link for SIMATIC ET 200SP or SM 1278 for S7-1200)

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 continuously maintain – a holistic, state-of-the-art industrial security concept. Siemens products and solutions only represent one component of such a concept.
