The EL4374 EtherCAT Terminal offers a powerful and parameterizable combined input/output for 10 V/20 mA signals
​​With the EL4374 EtherCAT Terminal, Beckhoff introduces a powerful analog I/O module to increase system flexibility and simplify parts management. The EL4374 is a multipurpose, combined input/output for -10/0 to +10 V or -20/0/+4 to +20 mA signals that can be used for standard automation tasks at a rate of 1 ksps per channel.
The ability to measure such a wide range of signals enables companies to use a single terminal in place of multiple specialized terminals, reducing cost and space requirements in I/O systems. As a result, engineers can easily adapt to evolving application requirements and stock fewer part numbers while improving readiness for unforeseen challenges and future application changes.​
The EL4374 terminal combines two analog inputs and two analog outputs in a compact 12-millimeter housing. Engineers can individually parameterize these channels for current or voltage mode using Beckhoff’s TwinCAT 3 automation software. The analog inputs and outputs are digitized with a resolution of 16 bits and transmitted to the higher-level automation device under galvanic isolation.
With a signal measuring range of +107% of the nominal range, the EL4374 terminal also supports commissioning with sensor values in the limit range and evaluation in accordance with NAMUR NE43. The outputs can provide up to 107% of the nominal value. In addition, the high output power allows a load of up to 750 Ω at 20 mA.
