All Field Analog temperature transducers are 2-wire transmitters. You do not need a separate power supply, as the products are supplied with power directly via the 4 mA ... 20 mA measuring line. This reduces wiring effort.
Output loop-powered temperature transducer for transmitting up to 2 sensor signals from RTD and TC sensors, as well as from resistance and voltage sensors via 4 mA ... 20 mA. HART, Signal conditioners with SIL functional safety, Standard configuration, Safety Integrity Level (SIL, IEC 61508): 2, Systematic Capability: 3, Screw connection
