Fieldbus Process Interface – Temperature Multi-Input

Product description:

The TM-I connects up to 8 analog inputs for thermos couples, RTD with 2-, 3-, 4-wire, voltage and resistance signals and provides many remarkable functions that enable easy installation:

• sensor connections with intrinsic safety (Ex ia) for analog signals in Zone 0/Div. 1
• removable terminals
• DIP switch for configuration
• connection to fieldbus according to FISCO or Entity

The TM-I is certified intrinsically safe and as associated apparatus even when the fieldbus connection is not. The fieldbus powers the sensors and TM-I itself. Additional power and wiring is not required. Data, configuration, and alarms are communicated via one fieldbus address to the DCS. Inputs can be configured all at once or individually. This ensures high availability of the fieldbus segment and thus the process automation system.

• Cold junction compensation
• Detects and reports lead breakage and short circuit conditions
• For T/C, RTD 2-, 3-, 4-wire, voltage and resistance
• LEDS for power, communication, and error
• DCS integration via GSD and FDT/DTM

TM-I junction boxes are configurable with many options selectable:

• enclosure types: glass fiber reinforced polyester, stainless steel, aluminum
• cable glands
• grounding bar
