Application and selection

Requires a compatible EtherCAT controller/coupler and a correctly designed measurement circuit. The EL3443 is the 1 A input version. Higher-voltage turbine circuits require an appropriate voltage measurement interface within the terminal ratings. Specify other input variants separately.

Information for your quotation

Provide the controller/coupler, system voltage, CT ratio and secondary rating, required measured values, quantity and delivery postcode. Confirm wiring accessories, software configuration and commissioning scope.

Manufacturer image shows the EL3443 terminal and its connection diagram. Controllers, couplers and current transformers are separate unless included in the quotation.

Supply availability, included items, price, freight, lead time and warranty terms are confirmed in the written project quotation.
