EL3104
The EL3104 from Beckhoff offers four differential inputs and a signal voltage range of -10 to +10 V. Part of the EL EtherCAT Terminals series, this terminal delivers measurement error below ~0.3% of full-scale value, features a 16-bit resolution including sign, and provides an input filter limit frequency of 5 kHz.
With a conversion time of ~100 us and an internal resistance exceeding 200 kΩ, it ensures precise real-time signal processing and low input current draw. It supports distributed clock precision of under 1 us.
