The STT700 is an exciting new addition to the SmartLine Temperature portfolio and upgrades the widely-used STT250 temperature transmitter. The STT250 has been Honeywell’s main temperature transmitter with many decades of in-field use. The STT700 is a direct replacement for the STT250 and thus is suitable for the majority of process applications including those for control and safety while delivering excellent performance at a low installed cost.Features:SmartLine platform features including SmartLine Connection Advantage when used with ExperionSingle input supporting up to 4-wire RTD sensor connectionDual input option supporting up to two (2) 3-wire RTD sensor connectionsDigital accuracy up to 0.15°C for RTDCallendar-Van Dusen sensor constants inputHART7 communicationsDE communicationsField housing, head mount, panel mount and DIN rail mounting optionsTransmitter and sensor diagnosticsFM / CSA / ATEX / IEC Ex approvalsFull compliance with SIL 2 / 3 requirement Ordering Information Model STT700 Smart Temperature Transmitter No. Inputs 3 Dual TC or RTD sensor inputs (5 terminations) Output / Protocol H Analog Output: 4-20mA DCDigital Protocol: HART Protocol Approvals 00 No Approvals Required Safety E SIL 2/3 certified Housing 0 None End Cap 0 None Paint Option - Housing 0 Housing - standard offering Paint Option - Cap 0 End cap - no change Interface Selections 0 Integral Display: NoneButtons: NoneLanguages: None Lightning Protection P Lightning protection Mounting Arrangement 0 Bracket Type: NoneMaterial: None Customer Tag 0 No customer tag Unassembled Conduit Plugs & Adapters A0 No Conduit Plugs or Adapters Required Application Support 1 Standard Diagnostics Output Limit, Failsafe & Write Protect Settings 1 Write Protect: DisabledFail Mode: High> 21.0mA dcHigh & Low Output Limits(1): Honeywell Std (3.8 - 20.8 mA dc) General Configuration C Custom Configuration Accuracy and Calibration C Accuracy: StandardCalibrated Range: Custom (Unit data required)Calibration Qty: Single Calibration Certifications and Warranty FE SIL 2/3 Certificate Factory 00000 Factory Identification NAMUR Output Limits 3.8 - 20.5mAdc can be configured by the customer or select custom configuration Table Vc
