EL3255 | EtherCAT Terminal, 5-channel analog input, potentiometer, 300 Ω…50 kΩ, 16 bit
Measurement technology easily configured: Analog EtherCAT input terminals.
Measurement technology simply integrated: With the analog EtherCAT Terminals.
The EL3255 EtherCAT Terminal enables potentiometers to be connected directly. A stabilized power supply in the terminal and the ratiometric measurement of the input voltage offer the preconditions for precise measurement. On account of its high sampling rate and together with potentiometer position encoders, the compact 5-channel EtherCAT terminal represents an economical position detector.
The HD EtherCAT Terminals (High Density) with increased packing density feature 16 connection points in the housing of a 12 mm terminal block.
