Important note

Product information
The ACT20M-RTI-AO-S configurable temperature transducer isolates and converts analogue signals. An analogue RTD input signal (Type Pt100) is linearly converted into an analogue output signal and galvanically isolated. The power supply is galvanically isolated from the input and output (3-way isolation) and this is done with direct wiring or over the Weidmüller rail bus.
The ACT20M-RTI-AO-E-S configurable temperature transducer offers the same functionality but does not provide galvanic isolation.
