Designed for intrinsically safe signal acquisition in hazardous environments, the Beckhoff ELX1054 enables direct connection of up to four NAMUR field sensors located in Zone 0 or Zone 20. 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.

| Terminal Connection | Signal Assignment |
|---|---|
| Input 1 (Ex i) | Terminal 1 (+), Terminal 5 (-) |
| Input 2 (Ex i) | Terminal 2 (+), Terminal 6 (-) |
| Input 3 (Ex i) | Terminal 3 (+), Terminal 7 (-) |
| Input 4 (Ex i) | Terminal 4 (+), Terminal 8 (-) |
The ELX1054 is exclusively intended for applications requiring intrinsically safe (Ex i) signal processing. For standard (non-hazardous) applications, the Beckhoff EL1054 or EL1004/EL1008 can be used instead. Note that the ELX series must be fed using the specialized ELX9560 power supply terminal to ensure compliance with the required safety barriers and intrinsic safety standards. Mixing Ex i and non-Ex i modules on the same segment without the appropriate separation barriers (such as the ELX9012 distance terminal) is strictly forbidden.
When designing your loop, always ensure that the maximum inductance (Lo) and capacitance (Co) calculations match the Ex-certified values of your NAMUR sensors. 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.
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.
Mount the ELX9560 Ex-power supply terminal onto the 35 mm DIN rail to establish safe power contacts.
Slide the ELX1054 terminal into position along the rail guide, engaging the side-by-side double slot and key connection securely.
Using a standard flat-head screwdriver, depress the spring-actuation mechanism, insert the stripped NAMUR sensor wires, and release to lock.
Establish the correct separation distances between the Ex i intrinsic safety wiring and standard non-intrinsically safe cabling inside the cabinet trunking.
