The EL4374 EtherCAT Terminal is a multipurpose analog I/O module for -10/0 to +10V or -20/0/+4 to +20mA signals that can be used for standard automation tasks at a rate of 1 ksps per channel. The terminal combines two analog inputs and two analog 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 in accordance with NAMUR NE43. The terminal’s high output power allows a load of up to 750Ω at 20mA.
