Multifunctional EtherCAT terminal boosts analog I/O flexibility
EL4374 EtherCAT terminal serves as a multipurpose, combined input/output for -10/0 to 10 V or -20/0/4-20 mA signals that can be used for standard automation tasks at a rate of 1 kbps per channel. This ability to measure a wide range of signals lets users deploy one terminal instead of multiple specialized terminals, reducing cost and space requirements in I/O systems.
EL4374 combines two analog inputs and two analog outputs in a compact 12-mm housing. Users can individually parameterize these channels for current or voltage mode using TwinCAT 3 automation software. The analog inputs and outputs are digitized with a resolution of 16 bits, and are transmitted to higher-level automation devices under galvanic isolation.
With a signal measuring range of 107% of the nominal range, EL4374 also supports commissioning with sensor values in the limit range and evaluation in accordance with NAMUR NE43. Its high output power allows loads up to 750 Ω at 20 mA.
