The EL2732 output terminal uses a power switch to control mains voltage from 12 V to 230 V AC. The switching element is a triac. As a semiconductor switch, it is not subject to wear. The steady load capacity of a digital output is 1 A. The EtherCAT Terminal has two mutually locked outputs, whose signal state is indicated by LEDs.

Special features:

• Triac output
• 2 x make contacts with mutual interlocking
• Connection of ohmic and inductive loads from 12 to 230 V AC
• Suitable for conventional blind motors
• no power contacts
