TSHART-1620m Safe Analog Input FTA with HART Interface (16 Channels)

The TSHART-1620m module acts as the interface between field components (sensors, etc.) and the safe high-density analog input module SAI-1620m in Safety Manager. Featuring a HART interface, it supports signals from Class I, Division 2 Hazardous Locations. With sixteen analog input channels, it is suitable for both safety-related and non-safety-related applications. These channels connect via a system interconnection cable (SICC-0001/Lx) to a redundant pair of SAI-1620m modules.

Main Functions:

• Signal Conversion: Linear direct conversion of 0(4)-20 mA DC field signals to the signal levels of the SAI-1620m module.
• HART Compatibility: Enables connection to HART multiplex units from MTL or Pepperl+Fuchs (P+F).
• Power Distribution: Provides power supply distribution to each transmitter with voltage-current limitation, compliant with Hazardous Area Class I Division 2.
• Monitoring: Enables monitoring of the external power connected to the FTA module.
