TTH200, TTR200, TTF200 TEMPERATURE TRANSMITTER | SM/TTX200/SIL-EN REV. E 3
1 Application area
The TTH200, TTR200, TTF200 *H Series temperature transmitter are 2-wire 4 to 20 mA devices for the temperature monitoring of
solids, fluids and gases of all types in containers and piping.
Combined with a temperature sensor, the temperature transmitter become a temperature sensor assembly.
The temperature sensors that can be connected to the temperature transmitters TT*200-*H for safety applications are:
• 2-, 3- and 4-wire RTD
• Thermocoup
le
The order variant ‘SIL2 - Declaration of Conformity’ meets the special SIL safety engineering requirements for the integration in
Safety Instrumented Systems in compliance to IEC 61508 Edition 2 part 1 to part 7.
The area of safety application is limited to:
• Up to SIL 2 as single transmitter installation
• Up to SIL 3 as redundant transmitter installation
• Mode of safety operation: Low Demand Mode
• Hardware Fault Tolerance: HFT 0 (as single transmitter installation 1oo1)
• Architectural Constraints: SIL 2 (based on Type B, HFT 0 and SFF â 90%)
• Systematic Capability: SC 3 according IEC 61508
The safety data, constraints, assumptions, installation / maintenance instructions and operating limits defined in the related
documents needs to be considered.
