It operates with a high resolution of 16 bits, enabling precise signal conversion and detailed diagnostic feedback for industrial automation processes. Featuring differential inputs, this terminal minimizes common-mode noise and ensures signal integrity in electrically active environments.\u003c\/p\u003e\n\u003cp\u003eAs part of the EtherCAT Terminal system, the \u003cstrong\u003eBECKHOFF EL3112\u003c\/strong\u003e connects directly to the E-bus for power and high-speed data transmission. The hardware design incorporates Distributed Clocks (DC) technology, allowing the analog inputs to be sampled with sub-microsecond precision, synchronized across the entire EtherCAT network. This makes the terminal suitable for fast, dynamic control loops and synchronized measurement tasks.\u003c\/p\u003e\n\u003cp\u003eIn addition to precise conversion, the terminal supports software-configurable options including activatable digital filters (FIR\/IIR) and limit value monitoring. The compact, DIN-rail-mountable housing includes status LEDs for active diagnostic signaling, ensuring clear local monitoring of terminal operation and network communication.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2 differential analog input channels for 0 to 20 mA current loops.\u003c\/li\u003e\n  \u003cli\u003eHigh-resolution 16-bit analog-to-digital conversion for precise process control.\u003c\/li\u003e\n  \u003cli\u003eDistributed Clocks (DC) support, enabling highly accurate network synchronization.\u003c\/li\u003e\n  \u003cli\u003eConfigurable internal digital filters (FIR and IIR) to reject unwanted signal noise.\u003c\/li\u003e\n  \u003cli\u003eComplete electrical isolation of 500 V between the E-bus and the analog signal circuitry.\u003c\/li\u003e\n  \u003cli\u003eCompact 12 mm housing width maximizing panel space efficiency.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-accuracy monitoring of standard 0 to 20 mA current transmitters.\u003c\/li\u003e\n  \u003cli\u003eDynamic closed-loop feedback systems in assembly and processing machinery.\u003c\/li\u003e\n  \u003cli\u003eMulti-axis machine synchronization requiring synchronized analog measurement.\u003c\/li\u003e\n  \u003cli\u003eIndustrial process control and distributed data acquisition networks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ch4\u003eGeneral\u003c\/h4\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eParameter\u003c\/td\u003e\n      \u003ctd\u003eSpecification\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eManufacturer\u003c\/td\u003e\n      \u003ctd\u003eBECKHOFF\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eModel\u003c\/td\u003e\n      \u003ctd\u003eEL3112\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Type\u003c\/td\u003e\n      \u003ctd\u003eEtherCAT Terminal\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eNumber of Inputs\u003c\/td\u003e\n      \u003ctd\u003e2 (differential)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eHousing Type\u003c\/td\u003e\n      \u003ctd\u003eCompact 12 mm terminal housing with diagnostic LEDs\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch4\u003eElectrical\u003c\/h4\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eParameter\u003c\/td\u003e\n      \u003ctd\u003eSpecification\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSignal Current Range\u003c\/td\u003e\n      \u003ctd\u003e0 to 20 mA\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eResolution\u003c\/td\u003e\n      \u003ctd\u003e16 bit (including sign)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInternal Resistance\u003c\/td\u003e\n      \u003ctd\u003etyp. 85 ohms + diode voltage\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMeasuring Error\u003c\/td\u003e\n      \u003ctd\u003e\u0026lt;
