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-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 thermoelements

Temperature monitoring relays for IO-Link
Notes:
Devices required for the communication via IO-Link:
- Any controller that supports the IO-Link (e. g. ET200S with CPU or S7-300 plus ET200S9 distributed peripherals)
- IO-Link master (IO-Link master 4SI IO-Link or 4SI SIRIUS interface module, which can connect all SIRIUS IO-Link devices to a controller)
Each monitoring relay requires an IO-Link channel.
