EL307x, EL4x7x: The new generation of multi-functional analog terminals

A new generation of Beckhoff analog I/Os

A new generation of Beckhoff analog I/Os

The EL4374 analog input terminal combines two analog inputs and two analog outputs that can be individually parameterized by the controller/TwinCAT via CoE for current or voltage operation. Depending on the setting, the channels process signals with 2 ksps in the range of -10/0 to +10 V or -20/0/+4 to +20 mA.

 

The inputs are digitized with a 16-bit resolution and electrically isolated before being transmitted to the higher-level automation device. As for the 16-bit-resolution outputs, these operate in the same way. With a technical measuring range of ±107% of the nominal range, the terminal also supports commissioning with sensor values in the limit range and the evaluation according to NAMUR NE43. The outputs are also capable of delivering up to 107% of their capacity.

 

Special features:

  • combined input/output terminal: 10 V/20 mA
  • 107% measurement/output range
  • high output power at 20 mA: load up to 750 Ohm
  • 2 ksps conversion rate per channel for standard automation tasks

Product status:

regular delivery
