EL3751-0024 | EtherCAT Terminal, 1-channel analog input, temperature, RTD (Pt100), 24 bit, 10 ksps, factory calibrated
EL3751-0024 | EtherCAT Terminal, 1-channel analog input, temperature, RTD (Pt100), 24 bit, 10 ksps, factory calibrated
Measurement technology easily configured: Analog EtherCAT input terminals.
Measurement technology simply integrated: With the analog EtherCAT Terminals.
The EL3751-0024 analog input terminal is a variant of the EL3751-0000 multi-functional terminal that has been reduced to resistance or temperature measurement (RTD). It 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 EL3751-0024 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. The signal state of the EtherCAT Terminal is indicated by LEDs. Each terminal has a unique ID number.
The individual Beckhoff factory calibration certificate can be downloaded here for each device. Recalibration (ZS9001) is possible via Beckhoff Service.
