Product Description:
The EL3114 is an analog input terminal manufactured by Beckhoff as part of the EL EtherCAT Terminals series. It converts process-level voltages into digital data that an EtherCAT controller can use for closed-loop regulation, logging, or alarm functions on automated machinery. By occupying only 12 mm of rail width and sharing the internal E-bus, the unit allows several channels of precise analog information to be collected directly beside drives, valves, or sensors on the machine frame. Its compact format also reduces the amount of control cabinet space required for multichannel signal acquisition.
The terminal provides 4 differential analog inputs, allowing each signal pair to be measured against its own reference while reducing the effects of ground shifts between the field and control cabinet. Conversion is performed with a 16-bit resolution, providing 65,536 discrete codes across the programmable measurement range. An analog front-end filter limits the incoming bandwidth to 5 kHz, helping prevent aliasing in environments with high-frequency electrical noise. The instrumentation amplifier tolerates up to 10 V of common-mode voltage without clipping. During operation, the terminal draws only 40 mA of contact current from the E-bus supply. All channels are sampled simultaneously, and the Distributed Clocks function aligns the timestamp of each reading with network-wide synchronization. Signals are referenced to a differential ground plane for consistent measurement behavior across the input channels.
The housing snaps onto a 35 mm DIN rail, and its polyamide enclosure has an IP20 protection class suitable for sheltered control cabinets. The internal electronics expose a process image consisting of 4 × 16 bits + 4 × 8 bits to the master, combining raw values with status and error bytes in a consistent cyclic frame. The converter uses simultaneous sampling, preserving phase relationships among the four channels for vibration analysis or power-quality diagnostics. The terminal supports a variable installation position, allowing it to be mounted according to the available cabinet layout. Its electronics supply continues through the E-bus connectors, so adjacent terminals receive power and clock signals without additional field wiring.
