Installation Guide

First, verify that the EtherCAT network power is completely disconnected. Then, mount the EL4114 on a standard DIN rail (35 mm). The terminal uses IP20 protection, so install it inside a control cabinet. After that, connect the 24 V DC power supply to the power contacts. The power contacts will provide daisy-chained power to adjacent terminals. Next, wire your field devices to the 4 output channels using 2-wire single-ended connections. Each channel outputs 0 to 20 mA. Ensure load resistance does not exceed 350 Ω. The output stages are short-circuit proof for added protection. Then, connect the EtherCAT bus coupler to the E-bus interface. The EL4114 communicates via the EtherCAT network. Then, apply power to the system. Configure the terminal using your EtherCAT master software. Set the watchdog parameters as needed for your application. For synchronized applications, activate the distributed clocks feature. Finally, download your configuration and test each output channel. As a result, the EtherCAT EL4114 will provide precise analog output control.
