  • Page 6: Safety Function

    5 Safety function The TTH300-*H, and TTF300-*H transmitter are configurable single or dual sensor channel (RTD 2/3/4 wire, TC) digital devices generating a temperature related analog 4 to 20 mA output signal. The safety function refers strictly to the analog output signal.

  • Page 7: Useful Lifetime

    TTH300, TTF300 TEMPERATURE TRANSMITTER | SM/TTX300/SIL-EN REV. E Useful Lifetime According IEC 61508-2, a useful lifetime, based on experience, should be assumed. The useful lifetime is highly dependent on the component itself and its operating conditions – temperature in particular.

  • Page 8: Constraints

    The DCS power supply for the transmitter must be capable to provide the required voltage level even when the current output is active with the configured high alarm. The head mounted electronics TTH300 with IP00 rating according IEC 60529 for the measurement loop must be protected against environmental influences by an suitable installation housing.
