Installation Guide

First, verify that all system power sources are completely disconnected. Then, mount the Beckhoff EL1862 onto a 35 mm DIN rail. Push the terminal down until the lock engages audibly. After that, connect the flat-ribbon cable to the 20-pin contact strip. Use AWG 28 flat-ribbon cable with 1.27 mm spacing. Press the cable into the insulation displacement contacts firmly. No stripping of wires is required. Then, connect the 24 V DC power supply to the power contacts. The power contacts pass through to adjacent terminals. After that, connect your 16 input field devices to the ribbon cable. Ensure the "1" signal voltage is between 11-30 V DC. The input filter provides 3 ms debouncing for mechanical switches. Then, connect the E-bus from the previous EtherCAT terminal. Apply power to the system. Finally, verify the 16 input LEDs indicate correct signal states. As a result, the Beckhoff EL1862 will provide reliable digital input acquisition.
