The EL3751-0004 analog input terminal is a variant of the EL3751 multi-functional terminal that has been reduced to resistance or temperature measurement (RTD). The EL3751-0004 measures to 5 kΩ full scale value in 2-/3-/4-wire connection. RTD temperature sensors (Pt100/1000, NI, KTY etc.) can also be connected.
The EL3751-0004 is particularly suitable for fast and highly accurate temperature measurements with a 10 ksps sampling rate. Even demanding temperature measurements are possible with the two freely adjustable numerical filters up to max. 39th order FIR/6th order IIR and the freely adjustable scaler with support point table.
