Safety characteristics
The safety characteristics necessary for using the system are listed in the "SIL declaration of
conformity". These values apply under the following conditions:
● The SITRANS TR200 / TH300 temperature transmitters are only used in applications with
a low demand rate for the safety function (low demand mode).
● The communication is used for the following purposes only:
– Device configuration
– Reading diagnostic values
● The devices are operated differently:
– SITRANS TR200: Operation via SIPROM T
– SITRANS TR300: Operation via SIMATIC PDM or handheld communicator
● The safety function test has been concluded successfully.
● The transmitter is blocked against unwanted and unauthorized changes/operation.
● The following condition applies to the transmitter:
– The current signal is evaluated by a safe system.
● The specified error rates apply to the typical demand of an industrial environment as in
IEC 60654-1 class C. IEC 60654-1 class C means a protected place of application, with
an average temperature of max. 40 °C for an extended period of time.
● The calculation of error rates is based on a MTTR of 72 hours.
The maximum application time of the SITRANS TR200 or TR300 in a safety application is
20 years. Replace the device after this time.
