The EL2602-0010 output terminal has two relays each of which has a single contact. The relay terminal switches at the zero voltage crossing to protect the contacts and is particularly suitable for capacitive loads such as LED lamps. A practical test was able to show that an EL2622-0010 remained fully functional at a capacitive continuous current load of 4 A after 200,000 switching cycles (for details see documentation). The signal state of the EtherCAT Terminal is indicated by light emitting diodes.

Special features:

• Relay output
• 2 x make contact
• Suitable for ohmic, inductive and capacitive loads
• contact-protecting switching of LED lamps
