Function: RD0-TI-Ex8.PA.*

The Temperature Multi-Input (TM-I) for DIN rail installation connects up to 8 analog inputs to the DCS via fieldbus. It is installed in a typically pre-wired field enclosure close to the sensors in the hazardous area. The TM-I is certified intrinsically safe and as associated apparatus: inputs are intrinsically safe even when the fieldbus connection is not. Analog inputs can be resistance temperature sensors with 2, 3, and 4 wires, measuring sensors, thermocouples, or millivolt signals.

The TM-I communicates all data, configuration, and alarms via one fieldbus address to the DCS. DCS integration utilizes GSD and FDT/DTM technology. Inputs can be configured all at once or individually. Fieldbus powers the sensors and the temperature interface itself. Additional power or wiring is not required.

Cold junction compensation for thermocouples is integrated. The TM-I detects and reports lead breakage and short circuit conditions.
