This compact EtherCAT terminal integrates high-density electrical isolation and comprehensive diagnostic features, allowing process automation plants to transmit field signals to the control level without additional external barriers. By combining intrinsically safe inputs and EtherCAT communication in a single 12 mm housing, it minimizes DIN rail space requirements and simplifies Ex-protection loop design.\n\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul style=\"list-style-type: square;

Thermal buildup can occur when placing multiple high-density Ex i modules side-by-side. Maintain standard 50 mm clearance above and below the terminal block to allow convection cooling. Failure to supply 24 V DC through the ELX9560 power contacts will cause diagnostic faults on the TwinCAT system, reporting standard E-bus power failure or field-side undervoltage.\n\u003c\/p\u003e\n\n\u003ch4\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003e\n  For wiring connection, use the spring-clamp terminals with standard 2-wire shielded twisted-pair cables. Strip insulation exactly 8 to 9 mm. Ensure that you do not mix the positive and negative terminals of the NAMUR loops, as this can trigger false cable break alarms (current below 200 uA). In TwinCAT 3, use the standard process data objects (PDOs) to monitor status bits for cable break and short circuit diagnostic errors per channel to enable rapid remote troubleshooting.\n\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cdiv style=\"background-color: #fff5f5; border-left: 4px solid #c53030; padding: 1rem; margin-bottom: 1.5rem; color: #9b2c2c;\"\u003e\n  \u003cstrong\u003eCRITICAL WARNING:\u003c\/strong\u003e High-voltage danger. Always de-energize the entire control cabinet before inserting, removing, or wiring any ELX-series terminals. Verify complete isolation and measure residual voltages before touching terminal contacts. Failure to strictly follow local Ex-safety regulations and Beckhoff installation codes may cause electrical sparks, risking terminal destruction, explosion in hazardous environments, or severe personal injury.\n\u003c\/div\u003e\n\n\u003cdiv style=\"display: flex; flex-direction: column; gap: 1rem; color: #2d3748;\"\u003e\n  \u003cdiv style=\"display: flex; align-items: flex-start; gap: 0.75rem;\"\u003e\n    \u003cdiv style=\"display: flex; align-items: center; justify-content: center; min-width: 24px; height: 24px; border-radius: 50%; background-color: #2b6cb0; color: #ffffff; font-weight: bold;\"\u003e1\u003c\/div\u003e\n    \u003cp style=\"margin: 0;\"\u003eMount the ELX9560 Ex-power supply terminal onto the 35 mm DIN rail to establish safe power contacts.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv style=\"display: flex; align-items: flex-start; gap: 0.75rem;\"\u003e\n    \u003cdiv style=\"display: flex; align-items: center; justify-content: center; min-width: 24px; height: 24px; border-radius: 50%; background-color: #2b6cb0; color: #ffffff; font-weight: bold;\"\u003e2\u003c\/div\u003e\n    \u003cp style=\"margin: 0;\"\u003eSlide the ELX1054 terminal into position along the rail guide, engaging the side-by-side double slot and key connection securely.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv style=\"display: flex; align-items: flex-start; gap: 0.75rem;\"\u003e\n    \u003cdiv style=\"display: flex; align-items: center; justify-content: center; min-width: 24px; height: 24px; border-radius: 50%; background-color: #2b6cb0; color: #ffffff; font-weight: bold;\"\u003e3\u003c\/div\u003e\n    \u003cp style=\"margin: 0;\"\u003eUsing a standard flat-head screwdriver, depress the spring-actuation mechanism, insert the stripped NAMUR sensor wires, and release to lock.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv style=\"display: flex; align-items: flex-start; gap: 0.75rem;\"\u003e\n    \u003cdiv style=\"display: flex; align-items: center; justify-content: center; min-width: 24px; height: 24px; border-radius: 50%; background-color: #2b6cb0; color: #ffffff; font-weight: bold;\"\u003e4\u003c\/div\u003e\n    \u003cp style=\"margin: 0;\"\u003eEstablish the correct separation distances between the Ex i intrinsic safety wiring and standard non-intrinsically safe cabling inside the cabinet trunking.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/div\u003e","brand":"BECKHOFF","offers":[{"title":"Default Title","offer_id":53106515902827,"sku":"ELX1054","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/3227\/0443\/files\/elx1054-fijgfkghuaq.png?v=1776244612","url":"https:\/\/www.plcprotech.com\/fa\/products\/beckhoff-elx1054-ethercat-terminal-4-channel-intrinsically-safe-digital-input-module","provider":"PLC ProTech Ltd.","version":"1.0","type":"link"}
