Description

The EL6851 EtherCAT Terminal is a DMX master terminal and enables connection of up to 32 devices without repeater. The DMX master terminal can send up to 512 bytes of data (this can be set via the terminal). At 250 kbit/s a maximum data rate of 44 kHz is therefore possible. The RS485 interface in the EL6851 is electrically isolated and guarantees high interference immunity.
