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 1 kbps per channel.

Measuring such a wide range of signals enables companies to use a single terminal instead 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 outputs in a compact 12-mm 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 under 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.
